Fourmile Lake Loop

Fourmile Lake Loop Professional Review and Guide

"You’ll find wildflowers, wildlife, a scenic lake, and waterfalls on this loop. The loop is done in clockwise fashion, traveling up the Anderson Trail and down the Fourmile Creek Trail.

At the trailhead you’ll find Anderson Trail 579 on the left and Fourmile Trail 569 straight ahead. You can do the loop in either direction (or forget the loop altogether and walk directly to Fourmile Falls, a popular destination). However, the Forest Service recommended that I climb the Anderson Trail and descend via the Fourmile Trail because of the steepness and deteriorating condition of the latter."

I think most folks like to just hike up to the waterfalls here, which is a nice 6 mile round trip from the trailhead. In that case, it is a really beautiful hike with amazing views all the way to the second waterfall. There are pretty aspen groves and flowers everywhere. For the longer, even more challenging day hike (or overnighter), this loop includes the Anderson Trail and can really be done clockwise or counter-clockwise. Be sure to drink in the awesome views of Pagosa Peak.

We found the Anderson trial portion of this hike to be wonderful with great vistas, wildlife and a trail in good condition. The portion of Four Mile trail from its junction with Anderson trial to Four Mile Falls is steep and rocky. The falls along this section were nice, but the trail was like walking down a dry streambed. From Four Mile Falls back to the trailhead was fine.

We only hiked from the trailhead to the falls. At the trailhead, they have a nice clean restroom (outhouse) and plenty of parking. The trail is well marked and has plenty of ups and downs but, nothing serious. This time of year (early May) there was plenty of water flowing and some snow in spots but, nothing impassable unless you are in tennis shoes. The wildflowers were just coming out in the sunnier areas. The wildlife was all around, mule deer (mostly in the lower elevations); blue birds and we even ran into an Elk. I think the Elk ran into us because we were sitting on a log drinking water when Mr. or Mrs. Elk came walking down the trail. When the elk got within about 30 feet, it saw us. Stopped,looked and took off. Yeah, the camera was in the backpack. Darn it. Nice trail for a moderate out and back. At an easy pace, it takes about four hours.
