See the map (download printable directions [427Kb pdf]) below to determine your best route into Thorny Mountain from Rocky Falls. Please note that the only access to this preserve is on foot.You must be able to read a topographic map and use a compass as there are no trails. This is very challenging hiking and there are many opportunities to get lost. We advise hikers to access the preserve through the Ozark National Scenic Riverways starting from the Rocky Falls' parking area.
