Coming from the East (Boise, Idaho for example), you'll want to take I-84 to The Dalles, Oregon.
Just as you get to The Dalles, you'll exit and cross over the salmon-pink bridge to the Washington side of the Columbia River.
After crossing the bridge, the road goes north for 3 miles before it dead ends into Highway 14. Turn left and head west for some seven miles towards Lyle. Along the way, you'll pass the famous Doug's Beach and if the season is right, lots of windsurfing.
After you pass through the two short tunnels, proceed on through Lyle.
As you leave Lyle, turn right on Highway 142 North.
Continue along the Klickitat river, passing through the town of Klickitat.
After you pass Mile Post 16,
go another half mile, and ...

and as you make the turn,
