With temperatures hovering around 40ºC and Madrid’s asphalt making the heat feel even worse, planning a getaway near the water is essential for the survival of anyone living in the capital.
But when the San Juan Reservoir starts to overflow, you have to look for alternatives, and the Alberche River offers a great one: a legal river sandbar for swimming, surrounded by trees, with beach bars, and about 50 kilometers from Madrid. It doesn’t have Blue Flags or lines of paddleboarders, but that’s precisely what gives it its charm—that classic picnic spot vibe, cool water, and fewer crowds compared to Madrid’s quintessential beach.
Alberche Beach is located in Aldea del Fresno, at the confluence of the Alberche and Perales rivers, in the southwest of the Community of Madrid. The river widens and gains flow right at this point, forming a broad sandy area with a sandy shore and shallow zones that make it a very comfortable spot for a relaxing swim.
One of Madrid’s legal river beaches
Unlike many unregulated swimming spots, Playa del Alberche is one of the few officially authorized river swimming areas in the region. The Aldea del Fresno City Council and the Community conduct regular water quality checks during the summer, and, when river conditions permit, swimming is allowed until mid-September. The water is shallow along much of the shore, making it especially suitable for children—always under adult supervision, as in any natural setting.
The atmosphere at the Alberche is relaxed: it’s still a well-known destination, but the type of crowd it attracts (families, groups, locals) and the very nature of the river sandbar make it less prone to the overcrowding of beach towels packed right up against each other. If you go on a weekday or first thing in the morning, it’s easy to find plenty of space to set up camp without feeling like you’re on the coast in the middle of August.
Amenities: beach bars, picnic areas, and shade
One of its strengths is that the recreational area is quite well-equipped. Around the sandy area , you’ll find picnic tables under the trees, drinking fountains, showers to rinse off the sand, trash cans, and a pedestrian path that connects to the town. Plus, there are several beach bars where you can grab a drink, eat a sandwich, or put together a full meal without having to lug a cooler around—something you don’t often find at river beaches like this. The entrance hasa paid parking lot during peak season, but it isn’t very large, so it’s best to arrive early to secure a spot.
If you want to go by car, the easiest way to get there is to take the A-5 toward Badajoz, exit onto the 32–37 (depending on your route), and follow the M-600 and M-507 to Aldea del Fresno, then turn off toward the M-510 and the sandy beach area. The trip is about 50 kilometers and takes less than an hour if you don’t run into heavy weekend traffic.
If you prefer public transportation, several intercity bus lines (541, 545, 546, 547, 548) depart from Plaza Elíptica and drop you off in the town; from there, you can walk to the swimming area or take a local taxi.
