The most common (and fun) way for tourists to get around the island is by golf cart. Rentals for the day are around 500 pesos (US$38). There are some attractions on the island, such as a turtle farm, paid view point on a cliff, and dolphin discovery, but we just enjoyed exploring the local town, eating the most delicious seafood lunch, and relaxing at Playa Norte, the beach at the north part of the island. There are tons of restaurants, cafes, and even eateries out of people's homes. It definitely feels a lot more "local" than Cancun.
La Casa Del Tikinxik, where we had amazing grilled fish. The seafood is grilled here, then brought over to the beachfront restaurant.
Out-of-this-world grilled/charred fish with rice, lettuce, and tons of lime, US$20
The best meal on our trip.
Soft, powder-like sand.
Beach chairs with umbrellas are available for rent by the day for around US$15. Make sure to bargain! Also note that the bathroom situation is less than ideal. Bring toilet paper/tissue and anti-bacterial with you.
