Cramped, but isolated
Campsites are pretty close together, there's a middle ground between sites where it may feel like people encroaching on your site. It's isolated from the city, though, so stargazing is a huge plus. Either bring firewood or buy it, they don't allow collecting, not that there's much to collect anyway.
They advertise reservable sites, but it's first come first serve. They also only allow 1 tent per site, more than 1 person is charged additionally.
