Pinnacle Rock Boat Ramp features two separate ramps—an upstream ramp suitable for backing vehicles and trailers close to the water, and a downstream walk-up/walk-down ramp for those not wanting to back down.

The upstream ramp can be very busy, especially during peak times, so drivers should scout available space and use extreme caution when maneuvering vehicles around pedestrians; the 15-minute load/unload time limit applies.

This is a common put-in for Bighorn Sheep Canyon (Class II-III rapids) and serves as access to the Arkansas River's most commercially rafted sections.
