We didn't have as much time to explore as I wanted, but here are some more photos from Maupin OR. I didn't get a photo of the city park that is right on the river and offers camping and amenities (see Maupin City link above).
I had checked out dining options ahead of time and thought The Riverside restaurant looked good. Our rafting guide raved about them, and we were delighted with their great food, large plates, interesting decor. The dishes may sound ordinary, but they are anything but! They have outdoor dining, but with the temps in the 90s, we were glad to eat indoors. https://www.facebook.com/riversidemaupin
All along the Deschutes River are places to picnic and camp, many with vault toilets and tables. Blue Hole has an accessible fishing dock as well.
I've been in a wheelchair for 30+ years. It poses some challenges for traveling. Maybe others can benefit from my experiences.
