There are plenty of cenotes near Tulum, but one that we've heard a lot about is Grand Cenote. I believe the pricing is $150 pesos or $10USD to get in, plus the cost of snorkel equipment. Grand Cenote is also a 17 minute cab ride from Cabanas La Luna.
For $65 pesos ($3.50USD) you can gain entrance to the Ruins of Tulum. Take a 17 minute cab ride from Cabanas La Luna.
Tulum is known for its amazing yoga scene. We recommend the below hotels that have yoga classes daily.
Yoga Shala- They offer multiple classes daily in a fresh, spacious and beautiful Palapa surrounded by lush nature. You can find their weekly schedule on their website.

Ahau Tulum- Ahau offers daily yoga classes and sunrise meditation in their beautiful oceanfront yoga studio. They also offer Mexican Caribbean Kitesurfing & Paddlesurfing. See their website below!
Tulum has some AMAZING restaurants. Below are a few of our favorite spots!
Taqueria La Eufemia- One of our favorite spots that we found on our last trip. Cheap tacos & margs right on the beach. You can literally get up, leave your taco chillin, go swim in the crystal clear ocean, and come back to your tacos and margs without your toes ever leaving the sand. Great music, chill vibe, and gets packed late afternoon so try to get there a little early (1pm-ish?). If you come to Tulum a few days earlier you'll probably find us here tbh..
Casa Banana- The food at Casa Banana is SO GOOD! It's on the jungle side, so you're surrounded by lush nature and candle light. They serve the best of what Tulum has to offer with an authentic Argentine perspective: fresh ingredients. Try the beets if they have them!
Posada Margherita- Fresh homemade pasta in Mexico? Yes! Come here for a beachfront dinner, delicious pasta, and great cocktails. The decor of the restaurant is an added bonus. Your instagram account will thank you.
La Zebra- Great place to come hang for a bit during the day for lunch and drinks. Come on here Sunday afternoon and stay for the free Salsa lesson at 6pm!
La Nave Pizzeria- If you find yourself in the town of Tulum, stop by La Nave for brick oven pizza.
Papaya Playa Project- We've heard a lot about their Full Moon parties they have every weekend and they're supposed to be insane. Check out their website closer to March for the schedule. http://www.papayaplayaproject.com/events/
