Difficult but beautiful! They’ve moved the trailhead so now drive 2.7 miles from the Fire Station to three parking areas by the trailhead.

This trail might be moderate to the avid hiker but is nothing less that difficult to most everybody else. Done from Anthracite to Dark Canyon it is mostly downhill but is very primitive in form for much of the trail. Bring shoes with good ankle support. There is also a lot of over hanging brush so plan on getting wet if it just rained or the dew point is high.

All that said though, this is one of the most beautiful untouched drainages in Colorado with a large waterfall, gorgeous meadows, and scattered aspen stands all with a classic Rocky Mountain backdrop.

steep uphill and downhill sections. I'd rate it closer to a difficult rather than moderate hike. Make it shorter and easier by hiking it out and back to panoramic view of area at alpine meadow.

Trail was very beautiful. But it is not a moderate hike. Forest service rates this as very difficult.

Nice hike in late August. Beatiful alpine meadow full of flowers at 10000 feet. Expansive views.
