Loved by Fort Collins locals and visitors alike, here are some of the top ways to enjoy Horsetooth Reservoir this summer!

Get Out on the Water

Boating is one of the most popular ways to explore Horsetooth Reservoir. Whether you're planning to bring your own boat, or you're looking to rent a pontoon, ski boat, or jet ski from the marina, spending time on the water is the perfect summer activity. The long, narrow shape of Horsetooth Reservoir creates ideal conditions for cruising, waterskiing, and tubing, all with an incredibly scenic backdrop.

If you want something a little more relaxed, kayaking and paddleboarding are fantastic options as well. Glide along the shoreline or simply float and take in the foothill views.

Designated swimming beaches at Horsetooth Reservoir also make it easy to cool off, and the water is refreshingly crisp on a hot Colorado day. Pack a picnic, bring some camp chairs, and settle in for a full day by the water.

Hit the Trails

Hiking

Horsetooth Reservoir is surrounded by miles of scenic trails that showcase the rugged beauty of northern Colorado. One of the most iconic hikes is the trek to Horsetooth Rock (6 miles round-trip with 1,400 feet of ascent), a distinctive rock formation that offers sweeping views of the reservoir and the plains beyond.

There are also plenty of more mellow hiking trails that wind along the shoreline or through the foothills, where you can enjoy summer wildflowers and occasional wildlife sightings. 

Biking

Mountain bikers will find plenty of singletrack trails weaving through the foothills, with terrain ranging from smooth and flowy to more technical and rocky. For road cyclists, the road along Horsetooth Reservoir is a long stretch with big views, rolling hills, and the occasional challenging climb.

Climbing

For any climbers in your group, Rotary Park on the east side of the reservoir is known as one of Colorado’s better bouldering spots. With climbing options for all levels, this spot is great for active groups looking for more than a lake day.

Horsetooth Half Marathon

If you happen to be visiting in the spring, don’t miss the Horsetooth Half Marathon. This scenic race winds through the foothills and finishes near the reservoir, making it a great option for a fitness-focused getaway. Even if you don’t participate, it’s a fun event to watch, with beautiful views and an energetic atmosphere.

Explore Nearby Lory State Park

 

On the west side of the reservoir, Lory State Park is a quieter alternative to the busier lake areas, with plenty of outdoor adventure focused on hiking, biking, and rock climbing.

One of the standout hikes is Arthur’s Rock Trail, a moderate 3-mile trek with panoramic views of Horsetooth Reservoir and the surrounding landscape. This park is also a hotspot for mountain biking, with well-maintained trails for all levels of bikers.
