We spent most of the day at this port-of-call on our veranda, reading. However, we did get off the ship and took a short walk. The area surrounding the cruise port is touristy, and slightly further away, quite depressed.
When we visited this port in the past, we taxi'd to the beach and enjoyed the day there.
We rented a jeep and drove around the island, stopping at a particularly charming bar along the beach. We enjoyed a beer and margarita, walked the beach, and did some exploring. Nothing particularly exciting, but it was exactly what we wanted. This vacation was more about relaxation than exploration, since we had been to both ports-of-call in the past.
