It's a quick drive to the main town of Isabel II and to the ferry terminal. Located in the safe, pretty and peaceful neighborhood of Bravos de Boston, sought out for its prime beachfront location and friendly neighbors. (No noisy roosters waking you up here!)
Aside from sustenance, there is no reason to leave! Renting a Jeep to get to grocery stores, restaurants, other beaches, etc. is strongly advised, though.
