Beautiful mountains, and tundra surroundings encompass the Guanella Pass area! From the parking lot, Rosalie trail (Tr 603) heads south. The entire length of Rosalie Trail is 14 miles but just hiking a short portion of 2.5 miles keeps you up above treeline until you meet Gomer Creek and its drainage (it then heads down into Abyss Trail and trailhead). We prefer the short portion of 1 mile in-and-out just for the views of the peaks, peaceful surroundings and cool air.
Its a good area to wander even if you aren’t up for a serious hike: take photographs, picnic, take-in the scenery and relax at an elevation of 11,700 ft. above sea level! If you have binoculars, you may see Rocky Mountain Big Horn sheep and/or mountain goats grazing on the side of Mt. Bierstadt!
Another short but interesting and fun trail heads east toward the valley – part of the beginning of Mt Bierstadt Trail. Hike down to the small pond or Gomer Creek and watch for wildlife; occasionally there are moose in the area.
The mountains that you will see on the Rosalie Trail include Mt. Bierstadt (14,060ft.), Mt. Evans (14,264 ft.), Geneva Mtn. (12,335 ft.) and others to the northwest. Straight ahead to the east is Mt. Bierstadt a very popular, â€œeasyâ€ fourteener. Many hikers, expert and beginner alike love this area.
Restrooms available at parking lot.
