Check out stretches up in Sunriver or down near Tumalo State Park. In Sunriver, you can float from Harpers Bridge to near the Sunriver Marina. Or at Tumalo, put in at the state park and float a stretch with some class I rapids down to near Highway 20.
There are other options but know your route. Stretches of the Deschutes can be extremely dangerous. If you’re sticking to the standard route in town and need gear or a shuttle, Sun Country Tours operates a rental station at Riverbend Park. They rent paddle boards and tubes.
For a shuttle, Cascade East Transit will be running their ‘Ride the River’ Friday-Monday, starting this weekend! ($1.50 per ride).
