The Deschutes (French for 'cascades') River http://orionexp.com winds through Bend, Oregon, and after miles of swiftwater melds with Pacific bound Columbia River near Biggs, Oregon. Between Bend and the confluence, the Deschutes River slices through mountain ranges and carves channels through ragged basalt bedrock creating dozens of fun Class III - IV white water rapids.
One of the pleasures of the Deschutes River, rarely mentioned, is it is always 'on the move'. Even during its mild stretches, the current is strong and relentlessly headed downstream.
The absolute BEST time to enjoy this unsung multi-day river rafting trip, only hours from Seattle, Portland and Boise, is during the spring months when the grasses are green, the campsites are fresh and no one but the random fisherman is on the river.
The other big positive for the Deschutes River is that it has sufficient flows throughout the year. So, whether your vacation time can be manipulated to enjoy the quiet, high water spring months or you can only make time for leisure during the popular summer months, you will find water in the Deschutes.
