My tip“This is the official swimming area (check the water level in summer). The car park fills early, and then you walk from distant lots. The only chiringuito is crowded and expensive, so bring your food. Take your waste back with you.”
Madrid’s inland “beach” on the San Juan reservoir between pine hills, the only river beach in the Madrid region authorized for swimming. Sand, clean water, and boating and kayak activities.
Moderate effort, needs a car
About an hour by car via the M-501, or bus 551 from Príncipe Pío. Walk down from the car park to the water (uphill on the way back); little shade on the beach.
Barbecue
Not allowed: the Madrid region bans barbecues and lighting fires in forest areas all year round, including recreation areas; bring ready-made food.
