Signal Mountain and South Signal Mountain are two small mountains that just manage to push their peaks above timberline. They reside on the very northeast corner of the Mummy Range. Signal Mountain is fourteen feet higher than South Signal Mountain but South Signal Mountain is more interesting with a small summit block that requires a bit of scrambling to reach the top. Both mountains make good winter destinations due to easy trailhead access and zero avalanche danger. There are well-maintained trails that go almost to the summits of both moutains.
The two most logical trailheads to start from are North Inlet Trailhead and Signal Mountain Trailhead:
North Inlet Trailhead: From the town of Glen Haven head east (downhill) 2.1 miles to Dunnraven Glade Road. Turn north onto the road and go 2.2 miles to the well-marked trailhead. It is roughly 6 miles and 3400 feet of elevation gain from the trailhead to the summit of Signal Mountain.
Signal Mountain Trailhead: From Fort Collins take Highway 14 west 35 miles and turn south onto Pingree Park Road. Follow Pingree Park Road for approximately 14 miles. The trailhead is on the left side of the road approximately 1.5 miles past the intersection of Buckhorn and Pingree Park Roads (there is very little parking). It is roughly 6.4 miles and 2600 feet of elevation gain from the trailhead to the summit of Signal Mountain.
No permits or fees are required if starting from any of the logical trailheads. Camping in RMNP is allowed only in designated campsites and requires a permit.
