Is there a beach near Madrid? Sounds like a joke. And yet, less than an hour's drive from the center, there is a spot that dispels all prejudices; we refer to Virgen de la Nueva Beach, located at the San Juan Reservoir, the only inland beach in the Community of Madrid with a Blue Flag. Freshwater, white sand, pine forests, nudist coves, water sports, and even a beach bar. Yes, all that, and without leaving the province.

Located in the municipality of San Martín de Valdeiglesias, this beach has been showcasing the most recognized quality distinction internationally since 2018. And not by chance: this is not just about taking a dip, but doing so with guarantees. To obtain and maintain the Blue Flag, the place must meet strict sustainability, cleanliness, accessibility, monitoring, environmental information, and water quality criteria. Virgen de la Nueva offers all that. And it delivers.

How to get there?

Getting there is simple. From Madrid, just take the M-501, known as the "road of the reservoirs," and in about 50-60 minutes, you'll be in a landscape that has little to do with the asphalt of the capital. Parking is free on weekdays, and costs one euro on weekends, with about 200 spaces available. There are accessible walkways, showers, restrooms, lifeguards, natural shade areas, and a beach bar. The beach is about 500 meters long, surrounded by pine trees, and has sand that can compete with some Mediterranean beaches.

Good, beautiful, cheap, and varied

But the San Juan Reservoir is much more than a beach. With 14 kilometers of coastline suitable for bathing, this reservoir is the only one in the Community of Madrid where swimming is legally allowed. The surrounding area also offers variety for all tastes; and indeed, for the whole family. If you're looking for something more adventurous, you can explore hidden coves like La Cala de la Lancha del Yelmo or La Cala del Cerro de San Esteban, which are quieter and less crowded. And if you're seeking total freedom, you can opt for La Cala del Tío Juan, also known as Nudist Cove or Shark Cove, where nudism is customary and permitted.

Virgen de la Nueva Beach and its surroundings are designed for all audiences. You can spend the day simply lying on the sand, taking a refreshing swim, or looking for a more active plan. The area allows for kayak rentals, paddleboards, or even trying wakeboarding and other water activities, all regulated and with authorized companies. For those who prefer solid ground, there are hiking routes that border the reservoir, with natural viewpoints like the one at Cerro de San Esteban, offering panoramic views.

It's also a popular destination for climbing enthusiasts, with over 150 equipped routes on the granite cliffs near the M-501 road. If you're going with family, there are safe bathing areas and enough space to play without crowding; and if you're looking for something more relaxed or naturist, you can always head to the nudist coves, where tranquility reigns. In short, it's such a versatile plan that it fits perfectly for a romantic getaway, an outing with friends, or a nature day with kids.

Additionally, the reservoir is part of the protected natural space of the Alberche Basin, so making fires, camping outside designated areas is prohibited, and it is recommended to respect the walkways and marked paths. The water quality is periodically tested, and it's safe for swimming according to the health reports from the Community of Madrid.

And what if you don't have a car?

If you don't have a car, there's also an option, as bus line 551 runs from Príncipe Pío to San Martín de Valdeiglesias, and from there you can walk about 5 km or take a taxi. However, if you're going on a weekend or in August, wake up early, because this inland paradise has earned its fame, and you won't be the only one wanting a piece of beach without leaving Madrid.

So, Madrileños, know that you can indeed say: "Wow, look, there really is a beach here." And the Virgen de la Nueva Beach is not a substitute. It is a real beach, with a blue flag, services, and clean water. It's a refreshing and convenient getaway, without needing to go to the coast. A place where Madrid takes a breath and temporarily becomes coastal.
