I have backpacked the trails here since the 1980s. More recently, I have taken my kids for several treks on the lower loop. Get there early and get to the campsites first, there are decidedly better sites in each camp. The water is good and I have never seen them dry. You will see lots of wildlife, we have seen salamanders, deer, snakes, a wild turkey even wandered into our camp in May 2018. Back in 1988, I saw two rattlesnakes together beside the trail on the northern loop. Moonville Tunnel is close and is a great bookend before or after your hike. I actually like to hike the lower loop backwards, starting on a Thursday. Treat yourself to a post hike meal at the Lake Hope Dining Lodge, Sunday brunch is awesome. Don't worry about stinking from the trail, the outside seating is dog and smelly hiker friendly.
