RMOTHG Trip – Abyss Lake Trail

A fine Fall colors hike up to the intersection of Abyss Lake Trail and Rosalie Trail. Beautiful meadow here at treeline with a fantastic view of Mount Bierstadt's SE ridge. At 8 miles / 1300 ft of elevation gain this hike will be moderately challenging - with the final mile being fairly steepish and rocky. Hopefully, we'll be treated to a Moose sighting - as they are a common sight in this area.

This trip is for BPX members. Feel and see the coming of fall, while enjoying the longest segment of the Colorado Trail. We'll hike three days, averaging 10 miles or so a day. Available camp areas along the way and a wonderful trail make for a fantastic way to spend three days in the embrace of Mother Nature, Always a good thing. IMO, of course.
