Overnighted August, 2018. Followed the loop counter-clockwise. The trail can be challenging to follow around big blow-downs and at the campsites on the southeast portion of the loop. Beware false trails and sudden turns. No major grades and only a few marshy areas. The frequent acres of ferns are the stuff of paintings. Except for the mosquitos it was a wonderful way to experience an encore backpacking trip after a 26 year hiatus.
