We spent the day at Playa Tortugas. The beach at our hotel was way too rough to enjoy. The water at Playa Tortuga is so calm and relaxing. We took our rafts and just floated in the water for hours. There is no entrance fee and there are shops/restuarnts all around if you get hungry, You can take the public bus there and it drops you right in front of the entrance. I definetly recommend it if you want a break from all the other tourits traps.
