State Park · Washington
A desert-reservoir park on Banks Lake in central Washington, anchored by a 600-acre basalt butte, with a summit hike, swimming, boating, and a large reservable campground.
Field briefing
Steamboat Rock State Park starts with access, not mileage.
Before you go
Reserve a main-campground site for summer, save the steep summit climb for a cooler part of the day, and treat the primitive and boat-in sites as first-come backups.
The landmarks worth the trip. Tap any photo to enlarge.
Weather, crowds, and what the season changes about the trip.
Mild and windy, with green coulee country and cool water before the summer rush.
Pack Wind shell, layers, and sun protection for the exposed butte.
Hot, dry, and busy, with the reservoir and campground at peak demand.
Pack Sun protection, lots of water, swim gear, and an early-arrival plan.
Cooling and quieter, with good hiking and lower reservoir use.
Pack Warm layer, wind shell, and a headlamp for shorter days.
Cold and quiet, with first-come camping and reduced services.
Pack Insulation, traction, and a plan for limited facilities.
Steamboat Rock summit trail
The signature hike: a steep scramble up the side of the basalt butte to a broad 600-acre summit plateau with 360-degree views over Banks Lake and the Grand Coulee.
Banks Lake recreation
Swimming beaches, boat launches, and warm-water fishing along 50,000 feet of freshwater shoreline.
Northrup Canyon
A nearby unit of the park with the area's only natural forest, a trail to a historic homestead, and a winter bald eagle roost.
Lock the boat, ferry, tide, or water access first, then fit the route list around that schedule. For one day in Steamboat Rock State Park, make Steamboat Rock summit trail the non-negotiable, add Banks Lake recreation only if the first stop runs clean, and keep Northrup Canyon as the flexible finish.
Turn Steamboat Rock's conditions into water, pack, and sleep-system decisions.

Getting there
Transfer plan
Steamboat Rock sits along State Route 155 at the north end of Banks Lake, between the towns of Coulee City and Electric City in central Washington, near Grand Coulee Dam.
Transfer plan
Most visitors drive in from the Spokane or Wenatchee side and base at the campground for boating and the summit hike.
Pair this with lodging: the best base is the one that protects the departure window, pickup point, or weather buffer.
For the developed campground, yes, especially in summer when it fills nearly every weekend. Reservations open up to nine months ahead through Washington's system. The primitive sites at Jones Bay and Osborn Bay and the boat-in sites are first come, first served.
It is a steep climb of about 4 miles round trip up the side of the basalt butte to a large summit plateau with panoramic views. The grade is strenuous and exposed, so carry water and pick a cooler part of a hot summer day.
Yes for day use. Washington requires a Discover Pass, about $10 for the day or $45 annually, to park for day use. If you have paid for camping in the park, the day-use pass is covered for your stay.
