Isla Verde
Isla Verde is a beach resort area in San Juan that includes some of Puerto Rico's top high-end hotels (it's only a short cab trip from here to Old San Juan). The lengthy stretch of sun-kissed sand beach features calm blue water, making it ideal for swimming. There are lifeguards on duty, as well as restroom and shower facilities, and a variety of seaside restaurants to choose from.
The golden sands of Isla Verde are bordered by tall palm trees, hotels, restaurants, and stores, making it one of the best beaches in the metropolitan region. You may rent beach chairs on the sand if you aren't staying at one of the resorts. There are also a variety of water activities available, including jet skiing and parasailing. The beach also has some excellent surfing, and if you don't know what you're doing, a local surf school can teach you how to do it.
