Rock Creek Basin is located in the High Uinta Wilderness, in between Rocky Sea Pass and Dead Horse Pass. Getting into the basin requires a minimum 9 mile hike; I highly recommend that you spend at least two nights in Rock Creek Basin to fully explore the area. Some people can backpack it in one night, but doing so won't allow enough time to see everything. There are three ways you can reach Rock Creek Basin: 1) via the Highline Trail from Hayden Pass 2) From West Black's Fork or 3) Rock Creek TH from the Stillwater Reservoir.
