Overview
The Snake River National Recreation Trail runs along the Oregon side of the Snake River within Hells Canyon in the Hells Canyon National Recreation Area, managed by Wallowa-Whitman National Forest. This section of trail, reached via the Dug Bar access point, is among the most remote trail destinations in Oregon: the drive to the trailhead requires high-clearance vehicles on rough roads, and the trail itself travels through canyon grassland at river level in one of the deepest gorges on the continent.
Spring is the optimal season by a significant margin. The canyon walls are covered with wildflowers, temperatures are comfortable at river level, and the river itself is in full spring flood character. Summer temperatures regularly exceed 110°F at river level; this trail is not appropriate for summer visits.
The Route
Dug Bar to River Bench (Mile 0 to 1.2)
From Dug Bar, the trail descends to river level and immediately enters the canyon character: sage, bunchgrass, and cliff walls rising thousands of feet above. The Snake River is fast, opaque green, and powerful.
River Bench Trail (Mile 1.2 to 4.0)
The trail follows a bench above the river, crossing several small side drainages and passing through periodic wildflower concentrations in spring. Bighorn sheep are commonly seen on the cliff faces above. The bench provides safe passage above the river without significant elevation loss.
Upper Section and Turnaround (Mile 4.0 to 3.6 turnaround)
The trail continues to a natural turning point near a major side canyon drainage. Return via the same route.
When to Hike
March through June is the only comfortable season for this trail. April and May bring the peak wildflower display and manageable temperatures.
October through November is possible in mild years for a shoulder-season visit with wildlife viewing.
July through September: do not attempt this trail in summer. Heat in the canyon regularly exceeds 110°F and there is no shade.
What to Bring
Many hikers carry 3 liters of water even in spring when temperatures are moderate. The river is available but treat or filter. In warm spring conditions, water needs are higher than the distance alone suggests.
A light wind layer and sun protection are important. Rattlesnakes are active in the canyon from spring onward; watch footfall carefully.
Trailhead Access
Dug Bar is reached by extending the Imnaha road system east from Imnaha. The final stretch is rough, steep gravel; a high-clearance 4WD vehicle is required. Do not attempt in a standard passenger car. No permit required (as of 2026). No restrooms.
Nearby
The Hells Canyon Bench Trail provides access to the canyon rim from a different trailhead with better road access. The Imnaha River Trail is within the same general Imnaha corridor.
