My wife and I took a 2-day backpack on this trail, starting at the Lost Park Campground to just below Bison Peak (perhaps 5-6 miles.) The trail climbs gradually to its junction with the Ute Trail at Bison Pass. There are nice meadow views along the way. Water on the trail gives out at Bison Pass where the trail then climbs rather steeply to the ridge near the peak. The reward is a marvelous 360 degree view of the surrounding Colorado mountains, one of our favorite all-time perspectives. The ridge also provides smaller versions of "Garden of the Gods" formations. We saw more elk (5) than people (4) on the trail, so traffic is not always high. A nice, worthwhile hike.
