We spent one night in Akumal in the lovely Hotel Que Onda, built several years ago as an artists retreat by Maribel Bianchi, a funny Italian-Swiss woman. The rooms and bungalows are very pretty and spread around a nice garden and swimming pool, and their little restaurant is also very good. The hotel is located few steps away from the beautiful rocky Half Moon Bay, where also the popular cenote and water park Yal-cu is, and where we had a wonderful first snorkeling dive of the trip. The next day we enjoyed the wonderful and very tourist-friendly Akumal beach, famous for turtles (that we didn't see!) and ate fantastic tacos at the cute Loncheria Akumalito.
Tulúm was supposed to be the highlight of our beach vacation and it completely enchanted us with its gorgeous beach, layback atmosphere and radical-chic décor of the places! We had booked the very pretty Posada Lamar, one of the many little eco-resorts -which the area is famous for- and that was perfect for us, with a nice two-story bungalow literally 50 meters from the white beach and a cool, shaded communal area with wood tables (where we had breakfast), chaise-longs and hammocks to relax.
All the boutique/hippie/boho posadas and resorts along the 2 km stretch of the FANTASTIC Tulúm beach are very similar: some bigger, some smaller, but all offering pretty much the same type of cozy, stylish and low-key experience. Most of them have also a little restaurant, among which the Italian Posada Margherita brags to be the coolest ;-)
The little road that connects all these places is very pleasant to walk on, especially for some cute little artisanal or artsy stores, while on the beach you can rent kitesurfs (like this one) and surfs, and do may other activities like yoga, spa treatments... that most of the wonderful eco-resorts proposes.
The main village of Tulúm pueblo is 10 minutes by car away from the coast and it has the very different and more down-to-earth atmosphere of a busy hub for the many locals working in the area's touristy places. Nevertheless it's worthy a stop, if only because it is filled with restaurants, shops and little travel agencies. We enjoyed eating there a couple of nights (our favorite dinner was at an Argentinian place), as the choice is a little more varied and less pretentious than the beach restaurants. There is also a big, modern supermarket at the beginning of the road heading to the costal area, where we bought fruits, bread and prosciutto for our lunches on la playa.
You can't go to Tulúm and not visit the amazing archeological ruins, the only Mayan city (and the latest to be built, before the Spanish colonization) by the Caribbean sea. We went there early when it opened, because we were told that it's better to visit it before the hordes of tourists buses arrive from the Riviera Maya resorts - and I am glad we did it because we got to enjoy an hour of almost solitude around the incredibly beautiful park and even swam on the beach down from El Castillo, the biggest pyramid by the cliff.
While in Tulúm we also snorkeled in one of the many cenotes of the area, Casa Cenote, which is quite big and connected to the sea bu a serious of underground tunnels - which are apparently very popular for scuba divers. Other cenotes that were highly recommended to us were also Dos ojos, Gran Cenote and Sac Actun.
Unfortunately we didn't have the time to explore the close-by Sian Ka'an Biosphere Reserve, which is a Unesco World Heritage site and it is supposed to be wonderful! By the way, I saw a very nice movie/documentary on Amazon that was shot right there: Alamar.
