Weir & Johnson Campground Boat Ramp offers a lightly gravelled launch suitable for backing trailers into Weir and Johnson Reservoir at 10,500 feet elevation on Grand Mesa.

The nearby campground provides 11 first-come, first-served sites with vault toilets and fire pits, though potable water is not available and the access road is approximately 8 miles of washboard road.

The ramp is best suited for smaller watercraft and trailers given the primitive conditions, with non-motorized boating allowed on the reservoir.
