Frequently Asked Questions

How challenging is jogging the Dillon Reservoir Recpath Loop?

The Dillon Reservoir Recpath Loop is considered a difficult trail for jogging, primarily due to its length (approximately 18.7 miles), significant elevation gain (around 1,560 feet), and high altitude (over 9,000 feet above sea level). The most strenuous section is the 3-mile climb up Swan Mountain to Sapphire Point, which features numerous switchbacks. While there are some relatively flat sections, joggers should be prepared for a substantial cardiovascular workout, especially if not acclimated to high altitudes.

What is the terrain like on the Dillon Reservoir Recpath Loop?

The trail is almost entirely paved with asphalt, providing a smooth surface for jogging. Despite being paved, the terrain is far from flat, featuring rolling hills, moderate climbs, and the challenging ascent of Swan Mountain. You'll encounter varied landscapes, from open spaces along the reservoir to wooded areas.

Is there a recommended direction to jog the Dillon Reservoir Recpath Loop?

Yes, for a gentler experience on the challenging Swan Mountain section, it's recommended to jog the loop in a clockwise direction. This offers a more gradual climb on a separated path. Jogging counter-clockwise involves a steeper, narrower shoulder that is shared with vehicle traffic for a portion, making it more strenuous and requiring extra caution.

What scenic views and landmarks can I expect along the route?

The loop offers breathtaking views of the Dillon Reservoir and the surrounding Gore and Tenmile mountain ranges. Notable points of interest include the View of Dillon Reservoir, the Frisco Marina Bay view, Heaton Bay and Sentinel Island Overlook, and the Dillon Reservoir Dam. You'll also pass through the Dillon Nature Preserve.

Where can I park to access the Dillon Reservoir Recpath Loop?

There are numerous access points and parking areas around the loop. Convenient options with amenities like restrooms include Frisco Adventure Park, Marina Park, and Sapphire Point Overlook. These locations provide good starting points for your jog.

Are dogs allowed on the Dillon Reservoir Recpath Loop?

The Dillon Reservoir Recpath Loop is generally dog-friendly. However, as a multi-use path, it's essential to keep your dog on a leash and practice good trail etiquette, especially when sharing the path with cyclists, walkers, and other users. Always clean up after your pet.

What is the best time of year to jog this trail?

The best time to jog the Dillon Reservoir Recpath Loop is typically from late spring through early fall (May to October) when the path is clear of snow and ice. During these months, the weather is generally pleasant, and the views are spectacular. Winter conditions can make parts of the trail inaccessible or hazardous due to snow and ice.

Do I need any permits or pay an entrance fee for the Dillon Reservoir Recpath Loop?

No, there are no specific permits or entrance fees required to jog the Dillon Reservoir Recpath Loop itself. The trail is part of Summit County's public recreational pathway system. However, as the trail is located within the White River National Forest, it's always good practice to be aware of any general forest regulations, which can be found on the summitcountyco.gov website.

Is the Dillon Reservoir Recpath Loop suitable for families or beginners?

Due to its length, significant elevation gain, and high altitude, the full Dillon Reservoir Recpath Loop is generally not recommended for beginners or very young children. However, families and beginners can enjoy shorter, flatter sections of the path, particularly around the Frisco and Dillon marinas, which offer a less intense experience with beautiful views.

What amenities are available near the trail?

The loop connects the towns of Frisco and Dillon, offering access to various amenities. You'll find restrooms at several access points like Frisco Adventure Park, Marina Park, and Sapphire Point Overlook. Both towns provide options for cafes, restaurants, and accommodation, making it easy to refuel or stay overnight.

Does the Dillon Reservoir Recpath Loop connect to other trails?

Yes, the Dillon Reservoir Recpath Loop is a central part of Summit County's extensive paved recreational pathway system. It offers connections to other trails like the Blue River Recpath and the Snake River Recpath, allowing for longer or alternative routes. The route also passes through sections of the Great Divide Mountain Bike Route and the TransAmerica Trail (Colorado).
