Mesa Falls Access provides a boat slide put-in at the Lower Mesa Falls Overlook parking area for rafts accessing the scenic "Cardiac Canyon" section of the Henrys Fork.

This is a steep, rocky canyon boat slide requiring unloading at the campground before launching; the section features fast rock gardens and Surprise Falls, making it suitable only for rafts and expert boaters.

Wade access is limited in this remote canyon section, though the Stone Bridge takeout is located 6. 7 miles downstream on river right.
