Cool Off in Boulder: The Top 3 Local Favorites for Swimming This Summer

When the summer sun shines down on Boulder, locals and visitors alike head for the water. Luckily, Boulder, Colorado is home to some of the best swimming spots in the Front Range. Whether you’re looking for a lively beach scene, a peaceful creekside splash, or a historic mountain pool, Boulder has a place for you to cool off. Here are the three most popular swimming spots in Boulder—and why they keep people coming back.

1. Boulder Reservoir
One of the largest and most beloved outdoor swimming destinations in Boulder, the Boulder Reservoir offers everything you need for a full day of summer fun. With a wide sandy beach, clear open water, and lifeguards on duty during the season, it’s ideal for families, sunbathers, and open-water swimmers. You’ll find restrooms, picnic areas, showers, and even a snack bar—all with mountain views in the background. Bring a float, a cooler, and a good book—you may never want to leave.

2. Boulder Creek at Eben G. Fine Park
For a more natural and spontaneous experience, head to Boulder Creek. The most popular access point is at Eben G. Fine Park, where the creek slows just enough for wading, splashing, or simply sitting in the cool current. During summer, the area fills with inner tubes, laughter, and the sound of water flowing beneath towering cottonwoods. It’s right in the heart of the city but feels like a quick escape into nature. Just be mindful of water levels and flow speeds, which can change quickly.

3. Eldorado Springs Pool
Tucked into a canyon just south of Boulder, the Eldorado Springs Pool offers a unique blend of history and scenery. This outdoor pool is fed by a natural mountain spring and surrounded by towering sandstone cliffs. With its relaxed vibe and cool, clean water, it’s a favorite for those looking to unwind after a hike or simply soak up the peaceful beauty of the canyon. A small entry fee applies, but the views—and the experience—are well worth it.

Plan Your Perfect Boulder Swim Day
Start your morning with a refreshing swim and beach walk at Boulder Reservoir. After lunch, cool down in Boulder Creek for a quick, playful dip. Then head to Eldorado Springs Pool to unwind, reflect, and watch the sun dip behind the canyon walls. Each spot has its own character—and together, they capture the magic of a Boulder summer.
