Lower Mesa Falls Boat Ramp is a steep, rocky canyon boat slide located at the Lower Mesa Falls Campground near Grandview, providing access to a remote 6.

7-mile raft section known as "Cardiac Canyon" with fast rock gardens and technical rapids suitable only for expert boaters and rafts.

The put-in requires unloading boats and dragging them down the steep slope to river left, with parking available at the separate Lower Mesa Falls visitor lot.

This is a critical takeout point—boaters must not miss it, as downstream waterfalls including Upper and Lower Mesa Falls are not boatable.
