This route was planned by komoot.
For jogging, the Komoot tour data suggests an average duration of about 1 hour and 8 minutes for the main route. However, this can vary significantly based on your pace, the challenging terrain, and whether you choose to explore around Timberline Lake.
The terrain is quite varied. It starts with a well-defined path but quickly becomes rocky and steep, especially at the beginning and in the final six-tenths of a mile before the lake, where inclines can reach a 19% grade. The middle 1.5 miles are generally flatter with gentle 5% grades. Expect several unbridged creek crossings, so your feet might get wet, particularly earlier in the season. Around the lake, you'll find dirt paths, boulders, and potentially swampy ground, making waterproof footwear a good idea.
Yes, dogs are welcome on the trail. However, as it's located within the Holy Cross Wilderness, all dogs must be kept on a leash to protect wildlife and ensure a pleasant experience for all visitors.
The trail is best enjoyed from late spring through early fall. Summer offers vibrant wildflowers and generally clear conditions. Early season (late spring/early summer) might involve snowmelt and wetter creek crossings, while fall brings beautiful foliage. Winter jogging is possible but requires appropriate gear and experience due to snow and ice.
No, there are no specific permits or entrance fees required to jog the Timberline Lake Trail or to enter the Holy Cross Wilderness area. However, standard wilderness regulations apply, such as Leave No Trace principles.
The Timberline Lake Trail is located near Leadville, Colorado, within the Holy Cross Wilderness. The trailhead is easily accessible and does not require extensive travel on rough dirt roads, unlike some other high mountain lake trails in Colorado. Parking is available at the trailhead, which is part of the Turquoise Lake recreation area. Arriving earlier in the day is recommended, especially on weekends, to secure a spot.
You'll experience diverse scenery, including pine forests, meadows, and the soothing sounds of Lake Fork Creek. In summer, wildflowers are abundant. The ultimate highlight is the Timberline Lake itself, a crystalline alpine lake nestled in a glacial basin, surrounded by craggy cliffs and verdant greenery. The lake is just shy of the timberline, offering stunning high-country views.
Yes, the route also passes through sections of the CDT - Colorado Section, the Colorado Trail, and the Colorado Trail Seg. 9 Tennessee Pass to Hagerman Pass Road. You'll also find it intersects with the ADT - Colorado C - Q - Seg 4, and the Timberline Trail itself.
While the trail is considered family-friendly for hiking, jogging with children might be challenging due to its 'difficult' rating for jogging, steep sections, and rocky terrain. The final push to Timberline Lake is particularly steep. Consider your children's experience and fitness levels before attempting to jog the entire route with them.
The Timberline Lake Trail is highly regarded for offering a substantial reward for a moderate effort. Its stunning destination, Timberline Lake, is a beautiful alpine lake with clear water, set in a glacial basin. It provides a true wilderness experience within the Holy Cross Wilderness, including opportunities for catch-and-release fishing. Unlike many other high mountain lake trails, it's easily accessible without long drives on rough roads, and you can walk around the entire lake for varied perspectives.
Given the varied and challenging terrain, sturdy trail running shoes, preferably waterproof, are highly recommended due to creek crossings and potentially swampy areas. Layers of clothing are advisable for changing mountain weather, and plenty of water is essential as there's no potable water source on the trail. Don't forget sun protection, snacks, and a map or GPS device.
