The glittering azure waters are an obvious draw for outdoor fun in San Juan. Beaches that open to the Atlantic are great for kitesurfing and surfing, while the reefs draw snorkelers and divers. The city's glassy lagoons and waterways are perfect for kayaking and paddleboarding. On land you can get out and about in the nearby green hills and mangrove forests.
Stick to the shore and cycling in San Juan can actually be good fun. In fact, it's perfectly feasible to work your way safely along the coastline from Old San Juan out as far as Carolina and the bike paths of Piñones.
Diving & Snorkeling
While Puerto Rico is well known for its first-class diving, San Juan is not always the best place for it, with strong winds often churning up the water. On calm days, though, Escambrón Marine Park offers good snorkeling from the shore and near Condado there's an easy dive that takes you through a pass between the inner and outer reefs into coral caverns, overhangs, grottoes and tunnels.
San Juan is an excellent base for serious deep-sea fishing for prized fish that include dolphin fish, tuna, wahoo, and white and blue marlin.
Most of the major resorts have in-house spas, which are also open to nonguests. Many are affiliated with international spa chains.
San Juan doesn't match Rincón in the surfing stakes, but no matter. You’ll find the best waves and biggest surfero scene east of Isla Verde out toward Piñones and beyond, when the morning and evening breezes glass off a 4ft swell. Popular breaks include Pine Grove and Los Aviónes along Hwy 187.
At most of the city's beaches, you'll find vendors that will rent you pretty much anything that floats, or simply take you for a ride: banana boats, wave runners, paddleboards, kayaks and small catamarans. Or get airborne with some parasailing or kitesurfing.
