Bitter Springs is a 28 miles back country road which connects I-15 to the North shore Road highway 167 located inside Lake Mead National Recreation Area near Echo Bay. The trail takes you by old mining roads and washes throughout the Muddy Mountains.
To reach the trail head, head North on the I-15 from Las Vegas. Exit the Valley of Fire offramp (exit 75), and turn right towards the state park, Valley of Fire. There is a lot of excellent camping in Valley of Fire.
Unless you have a need for fireworks or booze, proceed past the Moapa Indian Reservation store. After three miles the paved road bends left. The trail is the dirt road heading straight into the dessert towards the mountains.
