There are three beachfront areas in San Juan: Condado Beach at the western side near the bridge that connects this part of the city with Old San Juan; Ocean Park, further to the east; and Isla Verde, which is closest to the Muñoz Marín International Airport and has hotels of every shape and size. The Isla Verde beach, while not the absolute best the island has to offer, is advantageous because it is convenient to the airport and many shops and restaurants.
