The trailhead for the Colorado River Trail to Lulu City is located within Rocky Mountain National Park. You'll find parking at the Colorado River Trailhead, which is sometimes also referred to as the La Poudre Pass Trailhead on some maps. It's advisable to arrive early, especially during peak season, as parking can fill up quickly.
Yes, as the trail is located within Rocky Mountain National Park, you will need to pay the park's entrance fee. Additionally, during peak season (typically late May through mid-October), Rocky Mountain National Park often implements a timed entry permit system. You should check the official Rocky Mountain National Park website for the most current information on entrance fees and timed entry requirements before your visit.
The best time to hike the Colorado River Trail to Lulu City is generally from May to October. During these months, the trail is usually free of snow, and the weather is more favorable. Early summer offers lush greenery and wildflowers, while fall brings beautiful aspen colors.
No, dogs are generally not permitted on trails within Rocky Mountain National Park, including the Colorado River Trail to Lulu City. This is to protect wildlife and natural resources. Service animals are an exception, but pets are not allowed on hiking trails.
The trail is considered moderate. It begins with a brief, stiff climb, but then largely levels out, following the Colorado River. Much of the path is wide and relatively flat, making it accessible for many skill levels. While mostly an easy trek, some sections become more rugged as you progress up the valley. Sturdy hiking shoes are recommended.
You'll experience diverse and beautiful scenery, including mixed evergreen forests, aspen groves, and picturesque meadows with sweeping views of the Colorado River valley and the Never Summer Mountains. The trail follows the upper portions of the Colorado River. Wildlife viewing is a highlight, with opportunities to spot fox, elk, moose, deer, and even bears in the river and meadow areas.
The destination of this hike is the historic site of Lulu City Ruins, a former mining town from the 1879 silver rush. While most structures have decayed, you can explore remnants of old cabins, building foundations, and mining relics, including a rusting mining car and tailings from the Shipler Mine. The trail itself follows an old miner's route, adding to the historical intrigue.
Yes, you can continue hiking past Lulu City. A short but steep trail extends another mile to Little Yellowstone Canyon, offering beautiful, sweeping views of the Colorado River valley. If you continue even further, about three miles past Little Yellowstone, you'll reach Poudre Pass, which is the geological headwaters of the Colorado River.
Yes, due to its limited elevation gain and generally easy terrain after the initial climb, the trail is considered a great route for families. The historical Lulu City Ruins and wildlife viewing opportunities add to its appeal for all ages.
