Pinnacle Rock is a popular boat ramp access point on the Arkansas River featuring two ramps—an upstream ramp suitable for backing vehicles and trailers to the water's edge, and a downstream walk-up/walk-down ramp.

The upstream ramp can become very busy and requires careful maneuvering and spotting assistance; drivers should scout available space before attempting to back down, and the 15-minute load/unload time limit applies.

The site offers parking, restrooms, picnic areas, wildlife viewing stations, and serves as a common put-in for Bighorn Sheep Canyon trips.
