Following the Bitter Creek drainage in the Utah Rims area, just south of I-70 near the Utah and Colorado state line, Zion Curtain is an easy dirt road with vast desert scenery in a very desolate environment. The trail connects May Flat to a portion of the Kokopelli Trail. Trail surfaces consist of mainly packed dirt, with occasional exposed rock, including slickrock. The road is easily traversed by any stock high clearance pickup truck or SUV in dry conditions. If wet, it is best to avoid this trail as the dirt turns into to a sticky, greasy mud bog that will latch onto just about any vehicle and never let go. The trail is one vehicle wide the entire way, with plenty of pullout opportunities, but don't expect to see too many people in vehicles. This is a popular mountain bike area in the cooler months and remote enough that not many vehicles make the trek from Moab or Grand Junction.
Great dispersed camping is available along the entire trail. Pack out everything you pack in, including human waste.
