Trail Notes
Map of Dry Island Hike
The trail begins on a jeep road leading north, across Lower Crab Creek Road from the salt flat parking area. At 0.3 miles, one comes to the abandoned twin railroad bridges over Crab Creek. Climb up onto the railroad bed between the bridges and hike west over the recently refurbished span. For the next 800 yards, one has nice views down from the railroad bed into the marshes and riparian forests along Crab Creek. Look for herons, egrets, waterfowl and colorful blackbirds.

At 0.7 miles, where the marsh ends on the north and the first rock outcrops appear (GPS Point 1), turn off the railroad bed and start north cross-country through the sagebrush. Within 100 yards, one comes to grassy channels with willow trees winding among the basalt buttes. The easiest hiking is along these channels bottoms, following old cow trails north between the buttes. There's no correct route, but a prominent draw at 1.2 miles (GPS Point 2) offers easy access up toward Dry Island.

The hike continues north through the sage until one meets the powerline and road running east-west under the Dry Island escarpment. Walk west along the powerline road to where it descends into a deep, gentle swale, just below a hanging coulee to the north (GPS Point 3). This hanging coulee is the only obvious break in the rimrock and one follows old cow trails up through the break onto the rim of Dry Island. Once on top, the route is northeast up a broad grassy swale between low rimrocks. The cross-country walking is easy over loess soils with yellow balsamroot and other wildflowers in Spring.

At 2.4 miles (GPS Point 4), one reaches the highest plateau of Dry Island, where the route continues northeast through the sage steppe toward the north rim.
The easiest hiking is along narrow cheatgrass plains between the low basalt ridges. At about 2.9 miles, one reaches the north rim of Dry Island, with panoramic vistas over Sand Hollow Lake and the Jericho Coulee. Some spots along the rim have better views than others and one can easily wander east along the rim edge until a good lunch spot appears (GPS Point 5). Return as you came.

Road to Trailhead
From the north on State Hwy 26, 1.5 miles east of Royal City and 6.3 miles west of Hwy 262, turn south on Road E SW (aka Red Rock Coulee Road). Drive south for 3.7 miles to a "T". Bear right (west) onto Lower Crab Creek Rd and drive 6.9 miles, past the end of the pavement, to a large, salt flat parking area on the left (south).

From the west on State Hwy 243, turn east onto the Beverly/Crab Creek Road, just south of a huge railroad trestle bridge. Drive 9.2 miles east, past the Beverly Dunes ORV Area, to the large, salt flat parking area on the right (south) side of the road.

From the parking area, cross the road and start the hike north on a jeep track, heading toward the railroad trestles at Crab Creek. A WA State Discover Pass is required here.
