Plenty of room, but doesn't always matter. Closer to the city, so crowded on a weekend. Water pump functioned properly, though it takes around 30-40 to get it going. Porta potty services regularly.

Great access to the river, great space, bathroom access, and water pump. Would definitely go back.

Lots of space and a beautiful view of the water. It's also the loudest campsite I've ever been to. It's like sleeping in a train yard. Loud trains. All. Night. If I was a teacher, I'd send my kids to this campsite instead of giving them detention.

Peaceful with beautiful views. I did struggle with getting my bike up and down the steep hill with all my gear.
