Muddy Mountains Wilderness
Hidden Valley may be accessed by driving the Bitter Springs Backcountry Byway approximately three miles east on the Valley of Fire Highway from Interstate 15. About four miles south of the Valley of Fire Highway on this rough dirt road, turn right at the sign for Color Rock Quarry. About three miles further lies the trailhead for Hidden Valley. Four-wheel drive and high clearance vehicles are recommended as road conditions are rough and variable.
The Bowl of Fire and Anniversary Narrows are accessible from the paved Northshore Road. Callville Wash Road/Road 94 turns north off Northshore Road at mile marker 16. Four-wheel drive is recommended. Road 94A turns left off of Callville Wash Road, leading to Anniversary Narrows. From Callville Wash Road/Road 94, each of three main washes that intersect the Northshore Road lead to the Bowl of Fire.
