Nice Backpacking trip. We took about 30 Scouts and adults. There was water in the stream when we where there (late January 2020) and the pit toilets were open. Large space, there was another Scout Troop there of about 20 and plenty of camp space for everyone. There is NOT a bear vault bring your own. If there is water in the stream make sure you filter it. (other reviews said there was not water in the stream).
The "Valley Forge Campground" sign is deceptive -- it's placed 1.5 miles away and the trail was very overgrown. I recommend the fire road if you're a casual hiker like myself, cuz we took that back up. It's very exposed so be prepared.
Vault toilets were decent.
Lots of flowing water you can filter, we did that with out platypus gravity system and were fine. Refreshing!
Wildlife were mostly squirrels and butterflies, but bring the deet for dusk til dawn. Poodle dog bushes are abundant along the trail so be warned and wear long sleeves/pants.
