We are staying in Rio Mar for 5 days mid-march. Am wondering if a day trip to Culebra is feasible? Will be with 4 teenagers. How reliable is the ferry. I don't want to get stuck overnight in Culebra as the next day we fly back home out of San Juan. We are thinking of going on Tuesday, 3/21/2017. Any tips would be much appreciated.
You can take the ferry over in the morning and return later in the afternoon. Get your round trip tix at Fajardo. When you get to culebra you can take a bus to Flamenco beach for the day. the ferry is pretty reliable.
