The Bull Gulch Wilderness Study Area (WSA) is located in Eagle County 10 miles northwest of Eagle, Colo., and includes 14,364 acres of BLM lands.
The terrain in Bull Gulch is rugged with steep sided canyons and gulches draining into the Colorado River. The WSA includes colorful sandstone cliff formations with outstanding stratification as well as landslide deposits and volcanic instructions.
Vegetation cover is diverse and includes sagebrush, juniper-pinyon pine and mountain brush in the lower elevations; and Douglas fir, aspen, Englemann spruce, subalpine-fir and Ponderosa pine in the higher elevations. Riparian zones are present along the Colorado River, Alamo and Posey creeks.
From Wolcott, go north on Colorado 131 about 3 miles and turn left (west) on Milk Creek Road. Proceed about 2 miles to the trailhead, on the right by the power line. The trail follows the jeep trail running northwest.
LEVEL OF DIFFICULTY
The route is easy to moderately difficult, with a few steep stretches.
Elevations range from 6,400 feet along the Colorado River to 10,020 feet along the rim in the Black Mountain area.
