This route was planned by komoot.
This trail is considered difficult, with a significant elevation gain of over 3,500 feet. It features consistently steep sections, especially as you ascend, and varied terrain including dirt, rocky areas, and alpine tundra. While some lower sections might be runnable, the overall route demands a high level of fitness and experience for trail running.
The terrain on this route is quite diverse. It starts with a steep climb through a residential area and a large meadow, then enters pine and aspen forests. As you gain elevation, the trail becomes consistently steeper with long switchbacks. Above 11,000 feet, it breaks out into alpine tundra. You can expect varied surfaces, including dirt, potentially rocky sections, and even minor snow drifts near the top at certain times of the year. Some parts may also pass through burn scars from the 2021 Ptarmigan Fire.
The trail offers spectacular and continuously improving views. Early on, you'll get unobstructed views of Lake Dillon and the Tenmile Range. As you climb, gaps in the trees reveal views of the Gore Range. Above the treeline, the landscape opens up to expansive ridges with bird's-eye views across Summit County. From higher elevations and the summit, you can enjoy panoramic vistas of the Continental Divide, Gore Range, Tenmile Range, Williams Fork Range, Buffalo Mountain, Red Peak, Mt. Guyot, Bald Mountain, and Lake Dillon. Don't miss the View of Lake Dillon from Ptarmigan Loop Trail and the summit of Ptarmigan Peak.
The trail starts near Silverthorne, Colorado. While specific parking details aren't provided, it's common for trails in this area to have designated trailhead parking. Given its popularity, especially in summer, arriving early is often recommended to secure a spot.
Yes, the trail is located within the Ptarmigan Peak Wilderness Area, which is part of the White River National Forest. Dogs are generally allowed on trails in National Forests, but they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all users. Please remember to pack out all pet waste.
The best time to jog this trail is typically during the summer months, from late June through September, when the snow has melted from the higher elevations and the weather is most favorable. However, be prepared for potential afternoon thunderstorms common in the Rockies during summer. Always check weather conditions before heading out, especially for alpine sections.
The Ptarmigan Peak Trail is located within the White River National Forest and enters the Ptarmigan Peak Wilderness Area. Generally, there are no specific permits or entrance fees required for day use on trails within the White River National Forest. However, it's always a good idea to check the official USDA Forest Service website for the White River National Forest (fs.usda.gov/whiteriver) for the most current regulations, especially if planning an overnight trip or if specific area restrictions are in place.
For jogging, the estimated duration for this 16 km (10-mile) out-and-back trail with over 1,000 meters (3,500 feet) of elevation gain is around 2 hours and 40 minutes. However, this is an estimate for continuous movement. Your actual time will depend on your fitness level, pace, and how often you stop to enjoy the views or rest.
Yes, the route intersects with several other trails. You will find sections that overlap with the CDT iiyST, CDT ilcST, Ptarmigan Pass Trail, Ptarmigan Loop Trail, Ute Peak Trail, and Hyatt Ranch Connect Trail. These intersections can offer opportunities for longer or alternative routes if you're looking to explore further.
Given the trail's difficulty, significant elevation gain, and exposure above treeline, it's crucial to be well-prepared. Bring plenty of water, high-energy snacks, and layers of clothing suitable for changing mountain weather, including a windbreaker or rain jacket. Sturdy trail running shoes with good grip are essential. Sun protection (hat, sunglasses, sunscreen) is also highly recommended, especially for the exposed alpine sections. A map, compass, or GPS device is advisable, as is a first-aid kit.
The Ptarmigan Peak Trail is primarily an out-and-back route. You ascend to the peak and then return along the same path. While it intersects with other trails like the Ptarmigan Loop Trail, the main route to Ptarmigan Peak is not a full loop.
