THE GOOD: Few sites, and away from any traffic, so very quiet at night. Camp host was friendly.
THE BAD: Few flat spots for tents. Foliage not trimmed back in any area, incl. site driveways. Access to Hayden Lake is pretty sketch unless you drive 30 minutes. Switchbacks to the campground are a challenge, but just go slow: I made it in a RAM 1500 Crew Cab with a 24' RV trailer. Privacy between sites was so-so. Overall very unkempt, and run-down facilities and amenities. Unrepaired wind damage to sites, fallen trees, etc.
THE UGLY: Pit toilets unlit, gross, and not cleaned for at least 6 days according to list inside door. Most trash-laden campsite I have ever seen in my 40 years of camping; food, glass, paper waste. RV flat parking site was a challenge to get into. Another camper took 90 minutes to get into his with a 30' trailer.
FINAL: We will not return to this site. Just too poorly maintained and not worth the drive.
