Sun Lakes–Dry Falls State Park: Washington’s Alien Desert

Most people have never heard of this place—and honestly, that’s part of the appeal. Sun Lakes–Dry Falls State Park in central Washington is one of the most fascinating (and alien-looking) landscapes in the state.

Massive cliffs, sparkling lakes, crazy geology, and barely any crowds? Yes please. This park delivers hiking, camping, paddling, and biking in a setting that looks more like Utah than the PNW.

Let’s break down why this place is so epic—and why it should be on your radar.

So… What Even Is Sun Lakes-Dry Falls?

Dry Falls was once the biggest waterfall in the world—like, four times wider than Niagara Falls. But it wasn’t created by a river.

It was formed by massive Ice Age floods (called the Missoula Floods) that carved out the canyons and dumped insane amounts of water across the region.

Today, the water’s gone, but the giant cliff walls remain, creating a surreal desert basin filled with lakes, trails, and towering rock formations.

Epic Views: Dry Falls Vista & Visitor Center

Start your visit at the Dry Falls Vista Point, where you’ll get a jaw-dropping view of the entire park. It’s a total “wait, this is Washington?” moment.

The visitor center nearby explains the area’s wild geologic history, and it’s a good intro before heading down into the canyon itself.

Hiking & Biking Trails to Explore

Looking for the most worth it trails? We got you!

Umatilla Rock Trail

The massive Umatilla Rock towers above you at this trailhead, and the hike hugs the base of the formation.

It’s a unique, rugged trail with desert terrain, basalt cliffs, and big-sky vibes. Definitely bring water and sun protection—shade is minimal.

Umatilla Trail to Dry Falls Lake

This trail leads you deeper into the canyon toward Dry Falls Lake. The road to the trailhead gets a bit rough, especially after the toilet junction. If you have the right vehicle, you can continue and plop in a kayak for an afternoon paddle!

It’s scenic but overgrown in places. You can also reach the lake via a secondary trail that pops out near a vault toilet if the main route looks too brushy.

Lenore Lake Caves Trail

Just outside the main park, this short trail winds up to lava-formed caves overlooking Lenore Lake. It’s an easy, otherworldly hike with great views.

Park Lake Overlook Trail

This used to be a road, but now it’s a short 0.7-mile trail. If you walk to the southern end, you’ll get even better views of the lake and surrounding formations.

The Lakes: Paddle, Chill, Repeat

Dry Falls Lake

Tucked deep in the park with steep canyon walls around it, Dry Falls Lake is a peaceful paddling spot. The boat ramp is basic, and the road in is rough, but it’s worth it for the serenity.

Deep Lake

This lake has a small dock and a scenic trail alongside it. We saw fat bikers cruising by and paddlers out enjoying the calm waters. It’s a nice combo of chill and active.

Blue Lake

We only made a quick stop here, but there’s a public access point, a small dock, and a boat put-in. Think peaceful roadside lake vibes. Bring a picnic and a raft or paddleboard!

Alkali Lake

This one’s a gem. Free camping, one toilet, a pretty little shoreline, and total solitude. Rock walls and cool formations surround you—no one was around when we visited, and it felt like our own private hideaway.

Sun Lakes Park Resort & Vic Meyers Memorial Park

Located on Park Lake, this is the main hub of the park. There’s a resort, a marina, and picnic areas—some literally in the water!

It’s a bit more developed and family-friendly, with easy access to the lake. There’s also a great viewpoint above the lake where you can see the whole area spread out below.

Camping & Staying Overnight

There are several options depending on your vibe:

• Main campground: Great facilities and close to the resort
• Free camping: Check out Alkali Lake for that off-grid feel
• Sun Lakes Park Resort: Cabins and rentals if you’re not into tent life

We hope this guide helped you explore the stunning Sun-Lakes Dry-Falls State Park!
