This can be hard to find but worth an afternoon visit. There are a couple of entrances. The first one led us to an RV park which wanted a 200 peso entry fee. Don't enter here - go north several hundred yards to the entrance marked with the billboard. You are still required to pay a 200 peso entrance fee but if you spend 120 peso per person at the bar/restaurant you can get that refunded when you leave. Beautiful beach for swimming, snorkeling, walking and relaxing!!!
