Beachgoers relax and swim on a warm spring day at the Boulder Reservoir, one of Colorado’s most scenic and popular freshwater beach destinations.

Swim, Sunbathe, and Soak in the Views at This Scenic Summer Hotspot

When people think of Boulder, Colorado, they often picture the iconic Flatirons, endless hiking trails, and a vibrant downtown. But tucked just a few miles north of the city center lies something unexpected—a beach. Yes, a real beach with soft sand, a lifeguarded swimming area, and mountain views that take your breath away. Welcome to the Boulder Reservoir, recently hailed by Lonely Planet as one of the best beaches in Colorado.

A Beach Day Without Leaving Boulder

The Boulder Reservoir offers the quintessential summer beach experience without ever leaving town. Spanning over 700 acres, this multi-use recreational area is home to a large sandy beach, complete with picnic tables, restrooms, outdoor showers, and shaded areas for hot summer days.

From Memorial Day through Labor Day, the beach area is staffed with trained lifeguards, making it one of the safest places in Boulder to take a dip. Whether you’re swimming, building sandcastles, or just lying on a towel with your favorite book, this beach brings a true sense of vacation to Boulder locals and visitors alike.

Water Sports, Trails, and More

Beyond swimming, the Boulder Reservoir offers a full slate of water activities: paddleboarding, kayaking, canoeing, and even sailing. Rentals are available on-site, and there’s a designated area for non-motorized watercraft for those who want a more peaceful experience on the lake.

The 5.25-mile trail around the reservoir is popular with runners, cyclists, and walkers, offering a panoramic view of both the water and the surrounding foothills. It’s a great spot for birdwatching or catching a stunning sunset over the Rocky Mountains.

Family-Friendly and Community-Focused

The Reservoir is a popular gathering spot for families. Kids can splash safely in the water while parents relax nearby. Grassy areas provide the perfect setup for a picnic, while the on-site concessions stand offers snacks, drinks, and ice cream.

Seasonal events like triathlons, swim races, and beach-themed activities keep the community engaged and make the Boulder Reservoir more than just a place to cool off—it’s a centerpiece of Boulder’s summer lifestyle.
