Wallula Gap and Twin Sisters
Two basalt pillars on a bluff above the Columbia at Wallula Gap, the narrow pass the Ice Age floods squeezed through. It is the closest real scenery stop to the Tri-Cities.
What to do
- Walk the short, sandy path up to the Twin Sisters for views down the gap.
- Watch for hawks and eagles riding the wind over the river.
- Pair it with the McNary National Wildlife Refuge on the way home.
Getting there
Know before you go
- There are no restrooms, water or shade.
- Wind is constant and can be strong. Hold on to kids near the edges.
- Watch for rattlesnakes in warm months.
- Parking is free and no pass is needed.
