The Dillon Reservoir Recpath Loop offers a fantastic road cycling experience, circling the expansive Lake Dillon with constant views of the Tenmile and Gore Ranges. You'll pedal through diverse landscapes, from wetlands and forested sections alongside the Blue River to the panoramic vistas from Sapphire Point Overlook. The route is mostly paved, making it ideal for road bikes, but expect some rolling hills and a notable climb over Swan Mountain, adding a good challenge to the 20.3 miles (32.7 km) journey.
Planning your ride is straightforward, with plenty of free parking available along the path and access via the Summit Stage bus system. The full loop, with its 981 feet (299 metres) of elevation gain, typically takes around 1 hours and 38 minutes, making it a manageable yet rewarding outing. Keep in mind that while the official difficulty is easy, the high altitude (over 9,000 feet) and the Swan Mountain climb can make it feel more moderate, especially if you choose the steeper counter-clockwise direction.
This loop is a central part of Summit County's extensive paved recreational pathway system, connecting to other trails like the Snake River and Blue River Recpaths for longer adventures. It's renowned for its early season accessibility, often being one of the first trails to clear of snow in the spring. The continuous, dramatic views of Dillon Reservoir and the unique experience of riding across the Dillon Dam are major highlights, making this a must-do for road cyclists in Summit County, Colorado.

You'll enjoy panoramic views of the vast Dillon Reservoir and follow the picturesque Snake River corridor, passing through quiet meadows and sections of the White River National Forest. While the Dillon Nature Preserve itself is off-limits to bikes, it serves as a beautiful landmark along the route, providing access to incredible mountain vistas of the Gore and Tenmile ranges.

Parking is available at various access points along the Dillon-Keystone Trail, and starting earlier in the day is always a good idea to avoid peak crowds and enjoy the peaceful morning air.

This is a scenic spot to look out over the reservoir. The dam itself was built in the early 1960s and required relocating the original town of Dillon, which is now sitting beneath the water. Today, the reservoir holds Denver’s largest water supply and sends it through a tunnel under the Continental Divide. Surrounded by mountain towns, Dillon Reservoir is a popular locale for boating, fishing, and summer concerts at the lakeside amphitheater.
