2 mile backpack into box canyon and 2 night campout. Surrounded on three sides by tall basalt column cliff walls. Small water fall at northeastern corner. Incredible hiking up to top of rim and around to secondary canyon with a larger lake. You can also hike down towards the Columbia river where there is some additional camping available. Go in early spring for the green and cooler temps. You will want to bring a sleeping pad and tarp since ground is rough. Make sure you bring your own water! Even though there are lakes in the canyon, none of the water is safe for drinking due to the agricultural run off. Filtering will not work.
