Mackay Bar Campground sits on the north bank of the Salmon River within the Frank Church-River of No Return Wilderness, offering three primitive campsites with tables and fire grates ideal for remote wilderness camping and fishing.

Access is via the challenging Red River-Dixie Road #222 (44 miles of rough, winding terrain requiring low-range 4WD; no trailers), though the site is also accessible by jet boat, raft, or airplane via nearby Mackay Bar Ranch airstrip.

Basic facilities include vault toilets and river water (must be filtered/treated), with no potable water, garbage service, or cell reception available.
