Wonderful low key dispersed type camping in the amazing Smith Rock State Park. $8/night, no reservations but you can always find a spot because you're just pitching your tent wherever there's room. You park in a central area and walk to the camp area. No RV or car camping (you can't park here and sleep in your car). All cooking must be done in the designated area.

There are free showers for campers, flush toilets, host on site, and even a little free library/ book exchange.
