Depending on your interests, and where you would like to be in the Bend area, there are numerous options. Close to Bend (~3 miles NW) is Tumalo State Park. It's a very nice State Park (Google Oregon State Parks for information on this and other State Parks in Oregon) that I would be happy to stay at - if I didn't live about 3 miles away from it. Out by Sisters, there is a city park, Forest Service C.G.s', as well as some really nice dispersion (free) camping. If you want to be up in the Cascades along the Cascade Lakes Hwy, there are many Forest Service C.G.'s up there as well. East of Bend, there is plenty of dispersion camping. South of Sunriver, there is LaPine State Park or up at Newberry National Monument. There is also many private C.G.'s to choose from.
In-route will depend on your route. It is an easy day's drive - by whatever route you choose, but if you want to drag your heals a bit, I would suggest staying at a Forest Service C.G. up in the coast range and/or in the Cascades. Many options, again depending on your route and ability to stay at these type of campgrounds.
I am sure there are plenty of private C.G.'s between here and Cannon Beach as well. However, I tend to go for Forest Service or State Parks (or dispersion) camping, so I don't have any familiarity with them.
Good luck and safe travels,

I have searched the comments on RV Park Reviews and the Woodall's Book until I am blue and am thoroughly confused about where to camp for a couple of days on the way and also when we get to the Bend area. Any suggestions?
