Isla 101 - The Essentials

What You Need To Know Before You Go

Updated August, 2025

This little slice of paradise sits just across the bay from Cancún in the Mexican Caribbean. Isla Mujeres is small, a tad over 7 km from tip to tip and barely 800 meters wide at its chubbiest point, but it’s packed with charm, warm welcomes, and a laid-back vibe that’s hard to shake.

Picture colorful streets, soft white sand, clear turquoise waters, friendly locals, fresh seafood, and gorgeous tropical sunrises and sunsets. That’s Isla Mujeres.

This page isn’t a deep dive – it’s your first look, the minimum of what you need to know before you go, with links to all the details when you’re ready to explore more.

When is the Best Time To Go?

To get the specifics check Seasons of Isla – The Best Time to Go. But since you’re here…

It really all depends on your budget, heat and humidity tolerance and of course which activities you have your heart set on.

January to April: Gorgeous weather, loads of visitors, and high prices. The island is busy with events, festivals, live music, fundraisers and the 5 day Isla Mujeres Carnival.

May to August: It’s hot, humid, and a bit rainy but on the brighter side, fewer crowds and better prices. This is the only time for swimming with the Whale Sharks, particularly in July and August.

September to October: It’s still hot and humid. The lowest prices and the smallest crowds. But it’s also the height of hurricane season, so travel insurance is a must. You’ll catch Mexico’s Independence Day and plenty of local-centric celebrations.

End of October to November: The heat begins to fade, but the events calendar fires up. Kicking off with the Festival de Luz y Vida (Festival of Light and Life), a multi-day mashup of Day of the Dead traditions, Mayan lore with a sprinkle of Halloween.

December: The prices start rising, and the occasional Nortes (North winds) cool things down. A month of Christmas festivals, events, performances and parades celebrate the holiday season in Isla style

The grand finale? New Year’s Eve the island way, with fireworks, live music and dancing til dawn in the town square. And for those still awake or just woke up, our traditional sunrise gathering at Punta Sur to welcome the new year.

Weather note: Isla has its own micro climate, often far different than what you’ll see on weather sites. Get the weather details here

How To Get to Isla Mujeres

Here’s the bare minimum. We’ve got all the details on our How to Get to Isla Mujeres guide

Getting Here Is Easy (ish) 

Step 1: Fly to Cancun Airport.
Step 2: Get to the Puerto Juarez Ultramar Ferry.
Step 3: Hop the ferry to Isla Mujeres and there you are
Step 4: Have an AMAZING time!

Here’s the breakdown:  

Private transfer: Pre-booked, comfy, and quickest. Some even offer ferry tickets.

ADO Bus: Budget-friendly and slow. It goes to downtown Cancun, from there you’ll need a taxi, bus or rideshare to the ferry terminal.

Taxi/Van at airport: If you didn’t pre-book, you’ll pay more and might take a scenic tour of Cancun Hotel Zone drop-offs.

No Ubers on Airport grounds (that changes, then changes back again) There can be issues so pick another way.

Ferry tickets? Grab them online (Ultramar’s site, Puerto Juarez to Isla route), or check if your transfer service offers them.

Cancun Airport: Want to know what to expect? Fly over here

Are you coming from Cancun’s Hotel Zone, Playa de Carmen, Tulum or anywhere else along the coast? Go here.

Packing & The Practical

Get all the prepping and packing tips, tricks and helpful advice on Isla Mujeres Travel Tips.

What to Pack – The Basics:  
The obvious island gear: flip-flops, tropical threads, bathing suits, sunnies, lite sweater or jacket (winter months) and a hat. Leave room for Isla purchases. Stick to carry-ons and avoid checked bags if you can, you’ll save loads of time at the airport.

But let’s level up:

  • Ziplock bags (for that eternally soggy swimsuit)
  • Waterproof pouches (keep your phone sand-free and selfie-ready)
  • Motion-sickness bracelets (for boat days… trust us)
  • Two pairs of sunglasses (because the first pair will disappear into the Caribbean)

Leave the valuables at home. If it would break your heart to lose it… don’t bring it.

Electricity

Electricity: Same voltage and plugs as the U.S. and Canada (110 volts, Type A and B). You’re good to go unless your gadgets are from across the pond.

But Beware: Power outages happen, especially when every A/C on the island is working overtime. Bring a backup battery (just in case) and unplug before sleeping and during blackouts, the surges on return can fry your phone faster than you can say “Ay caramba.”

Stay Connected

Wi-Fi is most everywhere and sometimes even fast… for Isla!
Mobile networks work fine but the best you’ll get is 4G (if you’re lucky).

Avoid surprise charges:

  • Turn off roaming
  • Grab your carrier’s international plan
  • Or get a Mexico eSIM (cheaper and more reliable)

WhatsApp is the way to communicate on Isla. Locals, tour guides, food delivery – everyone uses it.

And don’t forget to download MapChick’s Isla Mujeres App – its your digital treasure map while on Isla.

Making Calls in Mexico:   
To call a number in Isla Mujeres from anywhere, just dial: +52 998 XXX XXXX.

To make an international calls when you are on Isla, start with the + sign (replaces the exit code), then the country code (1 for Canada and the U.S.), the area code and number. So, to call San Francisco while on Isla dial: +1 415 XXX XXXX

Phone Tip: Remember to TURN OFF ROAMING and lean on Wi-Fi for your calls, emails, and scrolling. 

Language

Spanish is the official language, with a sprinkle of Mayan words to spice things up.

That said, most tourism industry folks speak English and the rest are fluent in a combo of smiles, Spanglish, and hospitality.

It’s always good to know your ‘por favors’ and ‘gracias’, so check out our Basic Traveler Spanish.  

Money and Currency

The Mexican Peso (MXN) reigns here, though US dollars are welcomed with open arms. Word of warning if you use USD: Exchange rates at shops and restaurants are often… painful.

Your Best bet? Use the money exchange at the ferry terminal or withdraw pesos from bank ATMs in Centro.

Cards are not accepted everywhere, especially in small shops, taxis, and taco joints. Digital wallets like Apple Pay or Google Pay? Still a no-go on most of Isla.

Make sure you always have pesos in your pocket, a mix of bills in small denominations is best.

Credit card tip: Always double check the receipt before you leave. Is the charge in pesos or dollars? Any extra fees?

Health, Safety & The Water

Safety First (and Always): 
Isla Mujeres is one of the safest places in Mexico… warm, welcoming, and relaxed. But even paradise needs common sense. So, play it smart.

  • Keep your valuables safe, especially in crowded spots.
  • Don’t flash cash or wear flashy jewelry.
  • Don’t leave your stuff unattended — not on a table, a golf cart, or the beach.
  • Skip ATMs late at night.
  • Stay with your crew if you’ve had a few too many.
  • Don’t accept drinks from strangers.
  • Don’t buy drugs or hang out with people who offer them.


For those renting a Golf Cart or moped

  • Do NOT drink and drive.
  • Do NOT drive recklessly.
  • Do NOT let minors drive. Not a golf cart. Not a moped. Not “just a few blocks.”

Police are strict. Fines are expensive. Accidents happen everyday. And yes, tourists land in the hospital all the time.

Drive as if there’s a cop right behind you – because there probably is.

If You Need Medical Help

Isla Mujeres has wonderful English speaking doctors, dentists, and a hospital equipped to stabilize emergencies before a transfer to Cancun, if needed.

We recommend Farmacia YZA (three island locations; the one downtown is 24/7). Stocked, professional, and always helpful.

Bookmark our Helpful Contacts page – it includes emergency numbers, consulates and even laundry services.

The Water Situation

Let’s talk about tap water:  Totally fine for brushing your teeth. Not okay for drinking.

It’s not unsafe, but the high mineral content might send your stomach into vacation sabotage mode.

Stick with purified water, most hotels and rentals provide it, and bottled water is available everywhere. But do the island (and the planet) por favor…

Bring a reusable tumbler or pick one up here and fill it up at your hotel or rental. You’ll stay hydrated without creating a trail of plastic behind you.

Hydration Tips:
After a long beach day or a long night of tequila, down a bottle of Electrolit before bed. Believe me – it helps.

Starting to feel a little bit off? Drink more Electrolit or in a pinch – mineral water with lime and salt, the classic Isla cure.

If you really feeling off, seek Medical help. 

Isla Neighborhoods & How to Get Around

There’s a handy Neighborhood Cheat Sheet on the Accommodations pages for a quick guide plus a colorful map to help you picture the island layout at a glance.

The North End – Playa Norte & Centro:
This is Isla’s tourist playground. Picture beach clubs by day, street tacos by night, and margaritas at literally any hour. Hotels, rentals, shops, and restaurants are packed into a walkable 4 by 6 block grid that ends at Playa Norte, one of the best beaches in the world.

Airport Road:
Just south of Centro, this narrow stretch with an airstrip running down the middle leads toward the Colonias. No worries, there won’t be private planes flying 10 feet over your rental – it’s only occasionally used by military or government helicopters.

On the west side, you’ll find small marinas, cozy hotels, and sunset view restaurants. The east side is mostly waterfront rental homes with gorgeous sunrise Caribbean views, it’s not a swimmable beach – it is great for shell hunting.

The Colonias:
This is Isla’s soul, where locals live, kids play, and you’ll find some of the best food on the island. The vibe is colorful, authentic, and just a bit chaotic in the best way. Perfect for longer stays and curious wanderers who want to explore beyond the beach.

Sac Bajo:
A sliver of land that curves along the bay, Sac Bajo is home to luxury rentals, beachfront resorts, and a few beach clubs that define “tropical chill.” Fewer crowds, gentle waters, and amazing sunsets.

The South End:
The highest point on Isla Mujeres and the first place in Mexico to greet the sunrise. Punta Sur is where rugged cliffs meet ancient ruins, and luxury rentals have 360° rooftop views.

The west side, with spectacular sunsets and the twinkling lights of Cancun across the bay, is home to luxury resorts, boutique hotels, beachside restaurants, water parks, and vacation rentals tucked here and there. Busy with tour boats during the day, peaceful at night.

The east side is mostly upscale vacation rentals, jaw-dropping sunrises and endless Caribbean views. This is where you’ll find the iconic Shell House (yes, it’s real, and yes, it’s shaped exactly like what you think).

Getting Around: Transportation Tips

Your own two feet: Centro is made for walking. Ave. Hidalgo is pedestrian only (except the cross streets so watch out!).

Taxis: Easy to find and affordable. Cash only, no meters, so confirm the fare before you hop in.

Golf Carts: Fun, iconic, and handy to have if you’re staying in Sac Bajo or the South End. Otherwise, rent for a day (or two) to explore the island. Please drive safely and respectfully. Please Read This.

The Isleño Bus: Budget-friendly and fun, $20 pesos per ride or snag a hop-on-hop-off day pass for under $200 pesos. Prices subject to change.

Mopeds & Bikes: Good if you’ve got experience. If not… just don’t. The street are busy and taxis tend to drive fast. Helmets are a must.

Must-See Sights & Highlights

From cliffside sunrises to underwater art museums, Isla may be small, but she packs a punch. This isn’t the full list, it’s just the tempting treat before you dive into our deeper guides.

Playa Norte (North Beach): Soft white sand, palm trees swaying, and waist-deep turquoise water that goes on forever. Beach clubs and restaurants, each with a different vibe, line the shore. Spectacular sunsets every-single-day!

Punta Sur (South Point): The highest point on the island and the first place in Mexico to see the sunrise. Walk the paths winding their way around the Cliff of Dawn, check out the Mayan ruin dedicated to the goddess Ixchel, the statues of Mayan deities and ancient Isla life and snap your most liked photo ever.

Centro (Downtown): Colorful, walkable, and full of life! Explore markets, shops, street food and fusion restaurants, and murals everywhere. The Zócalo (town square), is especially lively during festivals and local events.

Explore the Island: Snap a picture with the giant whale shark statue, stroll the Caribbean-side malecón with sea life sculptures, climb the rainbow stairs, and hunt down murals, unique homes and local restaurants. Isla is full of photo-worthy moments. Check out Sights to See 

Get Wet: From shallow reef snorkeling to drift and wreck dives, Isla is a playground for ocean lovers. Don’t miss MUSA the Underwater Museum and if you’re here May–September, go swimming with whale sharks (yes, it’s safe. And yes, it’s life-changing). Explore Fun in the Water.

Pamper Yourself: Isla Mujeres isn’t just beach clubs, water sports, and zippy golf carts (though we do excel in those departments). It’s also a haven for rejuvenating your mind, body, and spirit, with a healthy dose of spa day pampering, because honestly, you deserve it. More info on Spa and Wellness.

Hook It & Cook It: Isla is known for both casual off-shore and world-class deep sea sport fishing. Most boats will clean your catch and point you to a local restaurant that will prepare it for you. Wahoo anyone?

Eat Tacos: Seriously. You’re on an island in Mexico. This is your taco era. Read Eat Like a Local and browse the Restaurant Directory

Want more? Our Isla Mujeres Things to Do section has all the details, whether you’re here to relax, renew, chase adventures or learn something new.

Sargazo - Sargassum: The seaweed situation.

If you’ve heard seaweed horror stories from other parts of the Mexican Caribbean, don’t panic — Isla Mujeres usually escapes the worst of it.

Thanks to the island’s location and current patterns, the west and north-facing beaches (like Playa Norte) are typically seaweed-free, even during sargazo season (roughly May through September). After storms, a bit might drift around the east side or the far edge of Playa Norte, but it’s rarely anything dramatic.

And if it does roll in?

Isla’s beach brigade is out early clearing it up before most travelers have finished their coffee. In over a decade, the island has only had a couple truly heavy seaweed events, and it was pretty much cleared by lunchtime.

For the latest on the seaweed situation, zip over to the Sargazo Updates Page on Facebook is a great resource.

Go see Playa Norte for yourself, live and unfiltered on the Hotel Ixchel rooftop cam or the YouTube stream.

Know Before You Go FAQs

The more time you have, the better. 3 to 5 day days on Isla allows you to hit the highlights, eat your way around the island and get plenty of beach time.

If you’ve got a couple of weeks in Mexico and you’ve never been to the Yucatan, explore! Start off with the Mayan Ruins, visit other gems like Valladolid and Mérida, and then come to Isla. Why? Because once you’re here, you’ll never want to leave.

It depends on your budget, heat and humidity tolerance and which Isla activities are on your bucket list.

Get the specifics on our Seasons of Isla – The Best Time to Go.

Yes. Isla is one of the safest destinations in Mexico, especially for families and solo travelers.

That said, use common sense: don’t flash cash, don’t leave drinks unattended, don’t wander alone late at night, stay away from drugs, and definitely don’t drive a golf cart under the influence.

No you shouldn’t. Use bottled water for drinking. Hotels and rentals provide purified water. Bring a reusable tumbler to refill and stay hydrated. Brushing your teeth with tap water? Totally okay.
Yes! Ice is made from purified water and delivered to restaurants in sealed bags. Restaurants and bars don’t make it themselves, so your frozen margarita is good to go.

Nope, but it helps. Most locals in tourism speak enough English to get by. A smile and a friendly “hola” or “gracias” goes a long way. Try a few basics with our Basic Traveler Spanish guide.

Pesos are your best bet. While most places accept USD, the exchange rate is rarely in your favor. Use ATMs located inside banks for better rates and safety.

Yes. Use the ones inside banks for safety and reliability or the ATMs inside Chedraui Super. Avoid freestanding machines, especially at night.

Sometimes. Many small restaurants and shops, as well as taxis, are cash only.

If you do use a card, double-check for extra fees and confirm if the charge is in MXN or USD.

Don’t let your card out of your sight.

If you’re coming from the U.S. or Canada, you’re all set. Isla uses 110 volts and standard A/B plugs. Otherwise bring one with you, they are difficult to find on Isla.

Downtown is walkable. For exploring beyond, taxis, golf carts, and buses are easy to use. Mopeds and bikes are available too, just wear a helmet and skip the moped unless you’ve got experience.

Golf carts are fun but not essential. If you’re staying downtown or Playa Norte, you won’t need one for your entire stay unless you plan to explore the island every single day (plus it will be parking nightmare). Rent a cart for just a day or two for exploring.

If you’re staying towards the south-end or Sac Bajo, it can be worth it.

Downtown is walkable, lively, close to the beach and restaurants. Great if you want to be in the middle of it all. The south end and Sac Bajo are quieter, scenic, and private. Read Isla Neighborhoods above or check out our Neighborhood Cheat Sheet on the Accommodation pages.

There are excellent English-speaking doctors, dentists, and pharmacies on Isla. The island hospital can stabilize emergencies before transferring to Cancun if needed.

Save our Helpful Contacts page just in case.

Honestly? Rarely. Most places ask you to toss it in the bin, the plumbing is delicate here. When in doubt, look for a sign or just ask. It’s not weird. It’s just Isla life.

Purchasing a roundtrip airport transfer is your best option. They will advise you what time you should catch the ferry to get to the airport in plenty of time.

If you prefer to play it by ear, taxis are readily available at the Ultramar terminal in Cancun.

Calling an Uber: You can try, but most will not pick up at the ferry terminal, it’s a Taxi stand. If they will, you’ll likely have to walk at least several blocks away from the ferry terminal to avoid potential issues with the taxi union. Don’t risk it.

Be safe – do not walk a block down the street and flag down a random taxi driving by.
