From the lower loop at Richland Campgrounds it's a short 200 yard walk to the first water crossing (Falling Water Creek).  If it has rained recently, be prepared to get wet! 

 

     Across the creek you'll need to find the worn path to follow along Richland Creek (Along your right) for 2 miles until the next water crossing (Richland Creek). 

 

     After you cross Richland creek find the trail going up Long Devil's creek (Along your right) (<1 mile).  Stay left at the trail fork to make your way to the top of Twin Devils Falls.  This is the last call for water, so fill up!  

 

     Between the two creeks, follow Big Middle Ridge up for a strenuous .9 miles until you find the Castles.
