Took the family (5) on this hike from the South Prong up to Fern Cave then back along the Haynes Ridge Overlook Trail and down the Canyon Loop Trail back to the parking and main road, and finally back up the road to the South Prong parking lot. Wow! What a hike with the wife and three kids (12, 9, and 7yrs). Beautiful scenry! Got some great pictures. It down poured the night before so there were lots of critters too. Roughest and most difficult part of the hike was up to Haynes Ridge from the South Prong. Rocky and steep. The trails have lots of brush in spots so long pants are a good idea. Take plenty of water with you on this one.
