River Description

The Weiser River offers a fun, family-friendly raft trip in April and early May. The most commonly run section is from the town of Midvale to the Galloway Diversion Dam. The trip is a 22 mile float that begins with several miles flowing through private agricultural lands, before narrowing into the canyon section.
The canyon is where you will find the whitewater with more than 7 miles of fun, splashy wave trains and a few hydraulics that are class II+ wave trains between 1500 and 2500 cfs. At higher flows, Class III hydraulics and waves usually appear in this section.
From Interstate 84, take exit 3 for Hwy 95. Travel approximately 40 miles on Hwy 95 until you arrive in Midvale. Turn right on Bridge Street. Cross the bridge and take your first left to access the unpaved put-in just upstream of the bridge on river left.
The take-out is a concrete ramp on river right just above the Galloway Diversion Dam. The ramp is approximately 1 mile downriver from the Presley Trailhead and parking area. There’s room for a handful of vehicles near the take-out ramp. Otherwise, park vehicles at the Presley Trailhead, and a drop off a passenger as you float by to drive down and meet you. Want someone to run your shuttle? Contact the Colonial Motel in Weiser at 208.549.0150 or the Frontier Motel in Cambridge at 208.257.4000.
Camping: This section is typically run as a day trip, however, primitive camping is possible. There are no designated campsites, so be sure you’re on public land, and bring all your drinking and cooking water, as well as everything you’ll need to Leave No Trace—including a portable toilet!
