Nice grassy area for tent sites. Hiker friendly. Clean bathrooms, plenty of hot water, no extra fee. Modern laundry machines that can do sleeping bags and puffies, open 24 hrs coin operated. Outlets for tech recharging (free), a cold drink machine also coin operated, and a gas grill that guests can use (free). Accommodating and efficient management.
Sure, at $20 a night it's not the absolute cheapest campsite, but it's clean, safe, friendly and has lots of facilities. And it's way cheaper than a motel.
I've stayed there five times now when making trips to Walker Pass and the Pacific Crest Trail down the highway from there. I will tell you it's a good place and I would stay there again any time.
