Palouse Falls State Park is in south-eastern Washington, and the easiest way to get there is to drive from Ellensburg, roughly 130 miles west. The shortest route takes Interstate 90 and connects to State Route 260, which connects to State Route 261 near the park boundaries.
Visitors arriving from out of state can fly into Yakima Airport, roughly 36 miles southwest of Ellensburg.
As of 2015, Alaska Airlines offers daily regularly scheduled service on turbo-prop aircraft. Hertz, Budget and Avis rental firms have counters in the airport terminal. Visitors may opt to drive from Yakima to Palouse Falls. The distance is roughly the same, but it usually takes longer because the road has many curves.
Once inside the park, State Route 260 leads directly to parking, an overnight camping area and hiking trails to Palouse Falls. The falls are north of the campground on the Palouse River, roughly 4 miles before it connects to the larger Elk River. Palouse Falls is 198 feet high and most impressive during the snow melt in spring and early summer.
All park guests must purchase an annual Discover Pass, which allows visits to all of Washington's State Parks. All 11 tent campsites are first come, first served at Palouse Falls, and require payment of an additional nightly fee.
