Overview

Flat Top Mountain is the highest mountain in the Flat Tops of Northwest Colorado. Despite being the highest summit in the Flat Tops, it is one of the easiest of the Flat Tops to climb. It is also one of the most popular mountains to climb in the Flat Tops as well, perhaps only exceeded by the summit of Devils Causeway, which is a "soft ranked" peak.

Flat Top Mountain is highly visible from the west, and is seen by many people driving along Highway 131. When viewed from the northeast or south, one might wonder how Flat Top Mountain got its name, but it’s really obvious when viewed from the southeast or northwest. Many beautiful lakes and meadows surround the peak. Flat Top Mountain is an easy climb from its west ridge and the gentle high ridges from the summit of Flat Top extend southeast to Dome Mountain.

The Flat Tops are more of a huge elevated plateau rather than a typical mountain range, but the plateau has been eroded into many individual peaks and summits, and most of them are flat-topped, or dome-like as are the Lost Lakes Peaks. The mountain area composing the Flat Tops contains over 110 lakes full of fish, and also has some of the most extensive areas above timberline in Colorado.

Getting There

The trailhead is at the Stillwater Reservoir. From Yampa, look for the sign on the west side of Highway 131 that points the way to "National Forest Access". Turn west on to County Road 7. Follow County Road 7 for seven miles, to where the road becomes FR 900. Stay on the main road for nine miles and drive to the parking area at Stillwater Reservoir. The road is good for all vehicles in day conditions. A 4wd may be needed early or late season.

The winter road closure varies. From mid-November through mid-April, the road is closed where the pavement ends (10 miles from Stillwater). In late April, another 7 miles of the road opens allowing access to Bear Lake. In early June (when the snow finally clears) the last 3 miles of the road opens allowing access to Stillwater Resevoir.

Routes Overview

West Ridge Route

The West Ridge of Flat Top Mountain is the standard route and by far and away the most popular route on the mountain. From Stillwater Reservoir, the North Derby Trail is followed south for 2.1 miles to the saddle between Flat Top Mountain and Peak 11815. From there, an unofficial trail heads 2.2 miles east along the gentle and beautiful ridge to the summit of Flat Top Mountain.

This route is 8.6 miles round trip with about 2200 feet elevation gain.

Other Routes

Other routes on Flat Top Mountain are very seldom climbed. You can reach the saddle mentioned above from several trails from the south and from the Stump Park Road, but this requires a much longer high and drive.

The north side of Flat Top Mountain may offer some interesting snow routes early season. The ridge from Dome Mountain to Flat Top would make an interesting route as well.

Backcountry Camping

There are some campsites along the trail between Stillwater Reservoir and the saddle. Beyond and including the saddle is open alpine terrain above timberline, so a perfect weather forecast has to be in place for considering camping there.

There are many beautiful, but popular campsites around Hooper and Keener Lakes south of the saddle.

When To Climb

Flat Top Mountain could be climbed year-round by an experienced climbing party, but the roads to Stillwater Reservoir is open only from around Memorial Day or early June to sometime in November, so outside this time period, this would probably be a three day trip.

The Flat Tops (especially the northern and western section) receive much snow, so despite the lower altitude than the 14'ers, the peaks remain buried in snow until mid-July. Snowshoes are recommended in June.

The Flat Tops have many mosquitoes in July, and sometimes into early August.

Mid August to mid September is good because the mosquitoes are gone.

From September and into December is hunting season, so wear blaze orange and use extreme caution. On the plus side, hunter traffic usually keeps the roads open until around Thanksgiving weekend. Late November might be the best time to make a “winter conditions” ascent because after the road closed, this would be very long trip.
