Roosevelt Park Recreation Site. Columbia River Gorge. Washington. (45.733498, -120.219748)
Nice public park right on the Columbia River. Free camping with a 14 day limit in any of the 3 parking areas. Park has restrooms with free hot showers, a large picnic area with a nice grass lawn and some shade trees, a boat launch with a dock, water access along the river, garbage collection, and a spot to fill up fresh water jugs. Strong Verizon signal.
Roosevelt is so small it doesn't even have a gas station, but their mini-mart serves up a really good burger and fries and sells a small selection of snacks, groceries, and even has a small cooler of perishables. Not cheap, but very handy when the closest supermarket is a 50 mile drive away. Post Office in town accepts General Delivery.
Supposedly a super popular place with windsurfers in the summer, but by early October most everyone had cleared out, giving Abby and I free reign over the place. Ended up staying the full 14 days allowed. 5/5 :)
