Green - 03. Echo Park (CO) to Split Mountain (UT)
Rainbow Park Campground serves as the access point for day trips on the Yampa River through Split Mountain Canyon. River permits are required, with two launches per day during the summer and one launch per day in the off-season. Most multi-day trips that begin upstream on the Green or Yampa River pass by this site on their way to the take-out at Split Mountain Boat Ramp. The campground offers four tent-only sites, each equipped with picnic tables, fire rings, food storage lockers, and vault toilets. It’s open year-round, though access can be challenging due to an unpaved road that becomes impassable when wet. No potable water is available, so visitors must bring their own, and campsites are available on a first-come, first-served basis.
