Rifle River-Rustic Cabins offers five rustic one-room cabins (accommodating six guests each) situated on lakes throughout the park, with one cabin on the Rifle River itself.

Each cabin features three bunk beds, a propane furnace, and outdoor amenities including a fire ring, charcoal grill, hand pump for water, and vault toilet, though guests must provide their own linens, cookware, and towels.

The cabins provide convenient access to the park's 14-mile multiuse trail and designated swim beaches, making them ideal for paddlers and anglers exploring the Rifle River and its 10 no-wake lakes.
