Boulder Reservoir

From Paddleboards to Picnics: Boulder Reservoir Has It All

Whether you’re looking to dive into adventure or just dip your toes into relaxation, Boulder Reservoir has you covered. Just a short drive north of downtown Boulder, this 700-acre multipurpose playground is more than just a body of water—it’s one of Boulder’s most beloved spots for locals and visitors alike.

A Place to Splash, Paddle, and Play

In the heat of summer, there’s no better place to cool off than the swim beach at Boulder Reservoir. Lifeguards are on duty, the water is crisp and clean, and the views of the Flatirons? Absolutely unbeatable. Kayaks, paddleboards, and canoes are available for rent, making it easy to get out on the water whether you’re a seasoned paddler or trying it for the first time.

Looking to break a sweat? The reservoir is a hotspot for triathletes, runners, and cyclists training on nearby trails or looping the scenic 5.25-mile Boulder Reservoir Trail. Many Boulderites use it as a fitness base, drawn to the combination of elevation, clean air, and awe-inspiring mountain views.

Nature’s Backyard

Beyond swimming and sports, the reservoir is home to a rich ecosystem. Keep an eye out for osprey nests, herons gliding above the water, or deer quietly moving through the grasslands. It’s a favorite location for photographers and birdwatchers who appreciate the mix of wetlands and open prairie.

Morning walks along the dirt paths provide a peaceful escape before the crowds roll in, making it a top sunrise spot to soak in Colorado’s early golden light.

Events and Community Vibes

Throughout the year, Boulder Reservoir also hosts community events like triathlons, paddleboard races, and seasonal festivities. With ample space and picnic areas, it’s also a favorite for birthday parties, graduation celebrations, and weekend barbecues. If you’re seeking a social scene in the great outdoors, this is your spot.
