This route was planned by komoot.
The trail starts at the Herman Gulch Trailhead, conveniently located just off I-70 near Georgetown, Colorado. There is a large parking lot available, but it can fill up quickly, especially during peak seasons. Arriving early is highly recommended to secure a spot.
This trail is generally rated as difficult for jogging, especially for beginners or those not accustomed to high altitude. The initial section is notably steep with switchbacks, and another challenging incline awaits closer to Herman Lake. The entire route is above 10,000 feet, which can make breathing harder. Good fitness and sure-footedness are essential.
The terrain is varied. The initial climb is steep, rocky, and can be sandy with loose pebbles. After this, it transitions to more gradual inclines through meadows and forests. You might encounter muddy spots, especially in forested areas. As you ascend above the tree line, the terrain becomes open alpine with rock cairns guiding the way to Herman Lake.
You'll experience breathtaking scenery that changes with elevation. The trail winds through lush meadows and pine and aspen forests, often alongside Herman Creek. In summer, especially July, meadows burst with wildflowers. Higher up, panoramic views of peaks like Pettingell Peak, the Citadel, and Hager Mountain emerge. The ultimate reward is Herman Lake, nestled beneath Pettingell Peak.
Yes, it is considered one of the most dog-friendly trails in Colorado. Dogs are welcome, but please ensure they are kept on a leash and that you pack out all waste to preserve the natural environment.
No, there are no specific permits or entrance fees required to jog the Herman Gulch Trail or to access this part of the Arapaho National Forest.
The best time is typically summer (especially July for wildflowers) and fall for vibrant foliage. While popular, summer can mean crowded parking. The trail also has year-round appeal; it can be enjoyed in winter with appropriate gear like snowshoes, as it largely avoids avalanche terrain.
The full round trip is approximately 10.3 kilometers (6.4 miles). For jogging, the average duration is around 1 hour and 49 minutes, but this can vary significantly based on fitness level, altitude acclimatization, and how much time is spent enjoying the scenery at Herman Lake.
Yes, a significant portion of the Herman Gulch Trail shares its path with the Continental Divide National Scenic Trail (CDT), specifically the CDT - Colorado Section. You'll also find sections of the Jones Pass Trail, Connector Trail, and Watrous Gulch intersecting or running alongside parts of the route.
Given the varied terrain and high altitude, wear sturdy trail running shoes with good grip. Layers are crucial due to changing weather conditions; bring a windbreaker or rain jacket even on sunny days. Don't forget plenty of water, snacks, sunscreen, sunglasses, and a hat. Trekking poles can be helpful for the steep sections and descents.
The trailhead itself does not have amenities like cafes or accommodation. However, the nearby towns of Georgetown and Idaho Springs, both easily accessible from I-70, offer various options for dining, lodging, and supplies.
