My tip“Rent for 2 hours in the morning before the heat; the centre also offers archery.”
Kayaking or stand-up paddleboarding (SUP) on the San Juan reservoir and the Alberche river, among pine-covered hills an hour from Madrid — Madrid’s inland “beach”.
Easy to reach, needs a car
On the bank of the San Juan reservoir near San Martín de Valdeiglesias; park near the launch point. Book in advance and wear a life jacket. Strong sun in summer, and beach restaurants. A car is practically necessary.
