Sites were very well organized and tidy. They supply a picnic table, fire pit, and two plastic Adirondack chairs (which we very much appreciated).
The road off the I90 is gravel but we found it ok. We only have a small truck and a low riding trailer and it was just fine. Signage is great. Check in was super easy and was done online via HipCamp messages.
The views are amazing and it is incredibly peaceful. Especially considering you are just off the Interstate. We liked it so much we are considering a return and stay for longer than just one night. There are a few things to see and do nearby so worthy of a longer visit.
