Pullman to Ellensburg Road Trip Guide: Best Stops & More

Begin on Washington State Route 270 from Pullman, a town that owes its grid layout to the Northern Pacific Railroad’s 1880s land grant. You’ll traverse the rolling Palouse, a region sculpted by wind-blown loess over millennia, then climb into the basalt canyons of the Columbia River Plateau before descending into the Kittitas Valley.

This 131-mile route connects two university towns—Washington State University and Central Washington University—but the journey itself is a lesson in Washington’s diverse geology. The drive typically takes about 2 hours and 15 minutes without stops, but planning for detours can easily stretch it to a full day.

Fuel is available in Pullman, Colfax, and then not again until Othello—a 70-mile gap. Plan to fill up in Colfax if your tank is below a quarter, and note that gas prices are typically 5-10 cents higher in smaller towns like Colfax compared to Pullman or Ellensburg.

Road quality is generally good: US-195 is a four-lane divided highway with a 60 mph limit, while I-90 is a well-maintained interstate with rest areas every 30-40 miles. However, rural sections can be narrow with sharp curves, especially near the Palouse River canyon.

• Cell service is spotty between Colfax and Othello; download offline maps.
• Construction typically occurs in summer; check WSDOT alerts before departing.
• Wind gusts in the Columbia basin can affect high-profile vehicles, especially from Othello to Vantage.

Winter driving from November to February can be hazardous, especially on US-195 where snow and ice are common; check pass conditions before travel. Summers bring heat waves, but the dry climate means comfortable camping and hiking. Always carry an emergency kit with water, blankets, and a flashlight.

For families, the route offers several child-friendly breaks: The Palouse Discovery Science Center in Pullman (ages 3-12), Butte Park in Colfax with its playground and picnic area, and the Ginkgo Petrified Forest State Park near Vantage with its interpretive trails and petrified wood exhibits.

Pets are welcome at many rest stops along I-90, but only service animals are allowed inside visitor centers. The Othello rest area has a designated pet exercise area with bags and water. For overnight stays, many hotels in Ellensburg are pet-friendly, but confirm in advance.

To combat fatigue, plan stops every 2 hours or 100 miles: the Ritzville Rest Area (milepost 220) and the Vantage Rest Area (milepost 136) offer scenic viewpoints and picnic tables. For hidden off-route spots, consider the Wild Horse Monument near Vantage, a series of steel horses on a ridge, or the Columbia River Gorge’s Wine Country, accessible via SR-243 south of Othello.

The Palouse’s rolling wheat fields give way to the coulees and channeled scablands carved by Ice Age floods. Steptoe Butte, a quartzite island rising 3,612 feet, offers panoramic views and is a short detour north of Colfax. Continuing west, the Othello area is part of the Columbia Basin Project, where irrigation transforms arid land into agriculture.

In Colfax, the historic Whitman County Courthouse (1903) anchors a downtown with local diners and antique shops. In Ellensburg, the 1886-founded downtown district features the Kittitas County Historical Museum and a thriving arts scene with over 20 galleries.

For a dose of culture without the crowds, visit the Palouse Falls State Park (not on the direct route but a 30-min detour via SR-261) where the 198-foot waterfall plunges into a basalt canyon. Alternatively, the Othello Sandhill Cranes Festival in late March celebrates the migration of sandhill cranes—a spectacle unique to this region.

Local commerce thrives on farm-to-table produce: stop at roadside stands for fresh apples and cherries near Ellensburg, or visit the Othello farmers market on summer Saturdays.
