My 15 year old son and I did this as a 2 day/1 night trip in November. It is a good trip. Good variety of terrain from walking ridgelines, walking the St Mary's river valley, and some just walking in the woods. You may find descriptions that list the blaze colors for these trails. That is a joke. We saw 6 blazes on the whole loop and 2 were more misleading than helpful. So plan some extra time for finding the trail in tricky spots, especially near the campsites. We probably spent 30 minutes total searching for the trail in 3 separate spots. The camp sites near Green Pond and Bear Branch are awesome. Worth a trip, just know that these trails aren't as well marked as most.
We tried this hike for the first time, going backwards from the typical route. We made this a 3 day/2-night trip, which spanned a weekend with evening thunderstorms and then snow on day 3. There are a few spots with large campsites, and ample creek crossings. My least favorite part was walking the fire roads, as it is not very exciting, but otherwise a great hike. Just to add, for those that like off-roaring or mtn biking, there are nice views and camp sites along the fire road. We opted to bypass the trip to the falls, but will definitely go back sometime.
