We had a Great time at Stone Island. This port didn't have much so our goal was to venture to Stone Island on our own. 4 of us got a taxi from the port to where you can get a water taxi to the island, cost was 10.00 total. The water taxi for 4 people was 7.00 total. Then we walked from there to the beach, took about 15 minutes. A nice walk watching all the locals go about their day. Ask the locals for directions, there isn't much for signs. Once we got to the beach we spent the day at Letys. For the first hour we were the only ones on the beach. Hardly anyone at the beach, there were more locals than turists. The ocean was great, very warm and you could walk out 100 feet before you couldn't touch bottom. The sand was silky grey black. Letys took care of us all day as we enjoyed the ambiance. Our total bill was only 42.00 total for 14 beers, 8 margaritas, 2 breakfasts and 3 lunches. They do take American money or pesos, but if you want to use a CC it depends on the signal. So take cash with you. Highly recommend a day trip to Stone Island.
