Rose Canyon Campground is a lovely getaway into the cool forest. Lovely vegetation and some interesting critters can be found here. Great for a night or two away from the city.
It is quite popular so if you're plan to reserve a spot for the weekend do so at least a month in advance. First come first serve spots fill up fast on the weekend too. Due to it's popularity it might be hard to get away from all of humanity, tho most fellow campers are respectful.
The facilities are limited (pit toilets and drinking water spigots) but clean and well maintained. The staff here is respectful and courteous. Great spot to camp.
