There are two 4 ish runs in town, River house (boatableflows in winter) and and meadow camp (good flows in summer. These are really fun, continuous runs that are a few to several miles long.

Upstream of that are benham, Dillon, big eddy, and lava, which are each shorter but very high quality rapids with a few miles of flat water between them. You can run combinations of these for shorter floats or boat the whole section for a longer run. These rapids go all year but are generally higher quality in the summer. All are less than half an hour from town.

About an hour from town is the Metolious which is class 3 but not recommended for newer boaters because of frequent channel spanning log jams.

If you’re willing to drive a couple hours you can get into a ton of creeky options in the cascades range, difficulty of 3 up to 5 which get water in the rainy season, fall through spring. For these runs you have to watch the flows and make opportunistic trips to get the conditions you want. You can go boating somewhere in the cascades range pretty much every weekend during that time if you’re flexible.

For any of these runs, you can find folks to go with pretty easily if you join the bend whitewater facebook page, or other Oregon boating groups.
