Start and finish at the large Hulls Gulch parking area on 8th Street, three miles up from the point where the street changes from pavement to gravel. The parking lot serves multiple users, including mountain bikes and dirt bikes, but only hikers and runners are permitted on the Upper Hulls Gulch Trail, which begins at the upper (north) end of the parking lot. (Alternatively, there’s a turnout with space for six vehicles about a quarter-mile farther up 8th Street; you can pick up the trail there.) This interpretive trail has several signboards along it which describe the flora, fauna, and natural history of the area. Wildlife from mule deer to rattlesnakes and occasionally elk are seen here, usually in early morning and evening. The trail begins at 3,800 feet, climbs about 1,000 feet in elevation, and is generally dry from April through October; it may be snow-covered (though rarely deep snow) from November through March.
