Dique de Ullum
Dique Quebrada de Ullum
A large mountain reservoir about 18 km west of the city, with brilliant blue water, where you can windsurf, kitesurf, and kayak, and climb Cerro Tres Marías for a panoramic view of the lake.
The reservoir was formed by a dam on the San Juan River and is surrounded by the arid Precordillera mountains. It is the favorite weekend destination of San Juan residents. Along the lakeside road on the east shore, there are several beaches, clubs, and restaurants where you can rent kayaks, stand-up paddleboards, and sailboats. Steady afternoon winds have made it one of Argentina's best-known spots for windsurfing and kitesurfing. Near the dam, you can hike up to the Cerro Tres Marías lookout, where the view is at its most beautiful at sunset. Entry is free. City buses run there, and driving takes about 25 minutes. Summer sun is intense, so use sunscreen and drink plenty of water.
