We have stayed at the Conch Shell for the paast 11 years. It is a clean, safe, budget hotel with a great porch, right on the beach a few doors north of Town Park. The Gonzalez family runs the hotel and they are great people. We get an upstairs room with a fridge to save money on our beverages & snacks.
Amigos del Mar Dive Shop is 10 steps away. This is where we rent our fins and snorkel around the dock. We also did an incredible night snorkel at Hol Chan with them.
A huge place was built next door, they may still be doing construction.
