NOTE: All recent reports I have seen indicate the Hole-In-The-Fence to Chac-Chi has been mended...
UPDATE: There seems to be a new hole (imagine that) in a different location. if you can't find it, I would ask at the Comisariato. They would know the location.
There are a number of buildings, palapas, "cabins", a restaurant/bar, a beach, and some not too shabby snorkeling.
Today's menu. I didn't get the price for anything except bottled water which was a buck and chilled.
