Soap Lake, Washington, is a small town best known for its mineral-rich waters, believed to have healing properties. Nestled at the start of the Coulee Corridor, it offers stunning landscapes, quirky but charming attractions, and outdoor activities. It makes for a memorable and off-the-beaten-path destination for roadtrippers looking to explore new places.

Tucked away in central Washington, Soap Lake is a small town with a big claim to fame—its mineral-rich waters, long believed to have healing properties. Once a sought-after wellness retreat, this unique lake continues to draw visitors looking to soak in its high-mineral content and explore the surrounding coulee landscape.

For centuries, local Native American tribes, including the Colville, sent their sick and injured to soak in its waters, believing in its restorative effects. During the 1920s, Washington State even promoted Soap Lake as the “world’s greatest mineral sea” and “Washington’s health resort” attracting visitors from across the state eager to experience its legendary benefits.

So how did this lake earn its unusual name and reputation? Well, it once had a distinctive soapy appearance, with water that felt almost oily to the touch. This slick texture came from its high mineral content—23 different minerals in total—but the cause of the foam remains a mystery.

Today, however, the lake looks quite different. Due to the construction of canals linking Soap Lake to upstream lakes and the Coulee Dam, its mineral concentration has declined, and the once-abundant soapy foam has all but disappeared.

But that hasn’t stopped visitors from coming to experience the legendary healing properties of Soap Lake! Beyond its mineral-rich waters, the town of Soap Lake itself offers quirky charm and many fascinating geological wonders to see nearby.

Whether you want to relax and soak in Soap Lake’s waters, explore the surrounding coulee country, or are looking for outdoor adventure, Soap Lake is the perfect off-the-beaten-path destination.

Visit Soap Lake

The main attraction in town is, of course, the “famous” Soap Lake—and honestly, it’s pretty impressive. The lake is quite large, and if you head to its southern shore, you’ll be treated to stunning views looking out toward the gorge.

To reach the southern shore, simply drive straight down the main street and keep going past the giant American flag—it’s hard to miss. At the end of the road, you’ll find a small parking area where you can get out, wander around, and snap some photos.

If you’ve brought water toys, this is a great spot to launch for a paddle. Or, if you’re feeling adventurous, take a dip and see for yourself if the lake’s legendary healing waters live up to their reputation.

Traveling with kids? There’s a small playground nearby where they can burn off some energy before you hit the road again. It’s a great little stop to relax, refuel, and soak in the peaceful surroundings.

Wander through downtown Soap Lake

Exploring downtown Soap Lake won’t take long—the main street short—but it’s worth a stroll. The charming buildings, unique vintage-style shops, and friendly locals give the town a laid-back, welcoming feel.

Along the way, you’ll pass Soap Lake Natural Spa & Resort, a lodge where guests can enjoy the healing properties of Soap Lake in the comfort of their own private jacuzzi, with mineral water pumped directly from the lake!

If you’re looking for a casual spot to grab a drink or a meal, Del-Red Pub is the go-to. It’s as local as it gets—unpretentious and no-frills, but they serve up solid burgers and fries. With limited dining options in town, this is the place to fill up before continuing your adventure.

With so much to see and do nearby, this is our top pick for a stay in the area.

Hike to Lake Lenore Caves

Hidden within the dramatic landscape of Eastern Washington’s Grand Coulee is Lake Lenore Caves, a fascinating natural wonder shaped by the cataclysmic Ice Age floods. These ancient caves carved into towering basalt cliffs offer an unforgettable experience for hikers seeking adventure!

The hike to the caves is short and relatively easy, making it an accessible adventure for most visitors. Beyond the caves themselves, one of the biggest highlights of this hike is the incredible view of the Columbia Gorge from the top of the trail.

You can find the trailhead for Lake Lenore Caves less than ten miles north of Soap Lake along Highway 17, also known as Coulee Corridor Scenic Byway.

Find the Blue Lake Rhino Cave

One of the most unusual fossils ever discovered in the Columbia Plateau is a mold and fossilized remains of a small rhinoceros. Found near Blue Lake in 1935 by a group of hikers, this remarkable specimen was identified as a mature Diceratherium, an ancient relative of the modern rhinoceros.

But how did a rhinoceros become so well-preserved in central Washington? Scientists believe the animal likely died in a small pond, and when lava flowed into the water, it rapidly hardened around the body, creating a natural mold. Over time, the remains decayed, leaving behind a perfect impression of the creature.

Today, adventurous visitors can explore the small cave left in the rhino’s shape. Located about 15 miles north of Soap Lake, getting there is part of the adventure. Start at Sun Village Resort, where you can reach the cave either on foot or by boat. If you opt for the water route, you can rent a rowboat from the resort and paddle across Blue Lake.

The cave itself is quite small—squeezing inside may or may not be possible—so bring a flashlight if you plan to peek inside.

Take in a show at Masquers Theatre

You might not expect to find a theater in a town as small as Soap Lake, but Masquers Theatre has been entertaining locals and visitors since 1979. If you’re staying in town—perhaps at Notaras Lodge or Smokiam Campground—and looking for something to do in the evening, check their website for upcoming performances.

Masquers Theatre puts on five productions a year, offering a diverse lineup that includes everything from classic and modern plays to comedies, dramas, musicals, and family-friendly shows. Whether you’re in the mood for a lighthearted laugh or a gripping performance, this community theater has something for everyone.
