One thing that makes Bend Oregon so awesome is that it’s bordered on the west by the Deschuetes National Forest. Like most national Forests Dispersed camping is allowed here as well. Take the Cascades Lakes National Scenic Biway (Hwy 372) Southwest out of town. You will come to a sign letting you know you are entering the National Forest. Right after this sign on the left is a Resort of some type. There is a large open area in the trees off the highway across from here. We saw several cars, trucks and vans parked here. There are several more Forest Service Roads on the right after this on the way to Mt. Bachelor and you can find a spot along any of these. There is a mountain bike trail system on the right so be careful you don’t pull off and block a trail. This should be pretty obvious.
There are 3 Sno Parks with pit toilets on the way to Mt Bachelor that are open 24/7 in case the woods doesn’t cut it for you. The Wanoga Sno park is also the trailhead area for the Funner 7 Tiddlywinks trail system.
HERE is the link to the National Forest Page for more information.
All these camp spots are for Vans or smaller. This is wilderness camping not an RV resort. There i a Walmart in town which allows rigs of any size to park overnight.
