When people think of natural hot springs in the Pacific Northwest, they usually jump to Oregon’s Bagby Hot Springs or Idaho’s backcountry pools. But Carson Hot Springs in Washington State sits less than an hour from Portland and just over two hours from Seattle, offering genuine mineral soaking in one of the most dramatic river corridors in the country. If you’re planning a trip to the Columbia River Gorge, it belongs on your itinerary.
Here’s what the experience looks like, how to get there, and how to build a longer trip around it.
What Is Carson Hot Springs Resort?
Carson Hot Springs Resort, formally known for much of its history as St. Martin’s Hotel and Mineral Springs, occupies a stretch of bottomland in the Wind River Valley, just north of where the Wind River meets the Columbia in Skamania County, Washington. The mineral springs here produce warm, sulfur-tinged water that feeds the bathhouse and outdoor pools year-round.
The property has been operating in some form since the 1890s, when the springs were first developed as a health retreat for travelers crossing the Gorge. Today the resort includes:
- Outdoor mineral soaking pools (the main draw)
- A historic bathhouse with private claw-foot soaking tubs
- Massage and body treatment services
- A nine-hole golf course, the only one in Skamania County
- Hotel rooms and cabins for overnight guests
The character is distinctly old-school. The bathhouse dates to the early twentieth century, the facilities are modest, and the whole property has a worn-in quality that appeals to visitors who want something authentic rather than a polished day spa. That authenticity is either the main draw or a minor deterrent, depending on what you’re looking for.
The Soaking Experience
The outdoor pools are the centerpiece. Two mineral pools, fed by the natural springs, maintain temperatures in the mid-90s to low 100s Fahrenheit. The exact temperature varies by season and flow rate, but the water is consistently warm enough to draw the tension out of a day on the trails.
The water has a mild sulfur smell. This is normal for mineral springs and fades quickly once you’re settled in. Some visitors find it off-putting for the first few minutes; most stop noticing it entirely.
The bathhouse offers a more private option: claw-foot soaking tubs filled with mineral water, rented by the hour. This was the original experience at St. Martin’s, and the tubs have a genuinely historic feel. If you’re visiting as a couple or want more quiet, a private tub booking is worth considering.
A few things to know before you arrive:
- Reservations are strongly recommended, particularly on weekends and summer holidays. Walk-ins are accepted when space allows, but the outdoor pools have capacity limits and fill up.
- Swimsuits are required in the outdoor pools. Private tubs have their own policies, which you can confirm when booking.
- The mineral water leaves a faint sulfur residue on skin. A shower afterward clears it easily.
- This is not a luxury spa. The appeal is the water and the Gorge setting, not interior design or curated amenities. Adjust expectations accordingly.
Getting There from Portland and Seattle
From Portland (approximately 50 miles, 1 to 1.5 hours): Take I-84 east to Cascade Locks, cross the Bridge of the Gods into Washington, then head east on WA-14 for about 16 miles to the town of Carson. The resort sits just off WA-14 on Hot Springs Avenue. The drive through the Gorge, with basalt walls rising above the Columbia, makes the approach feel like part of the experience.
From Seattle (approximately 155 miles, 2.5 to 3 hours): Take I-5 south toward Olympia, then connect to I-205 and cross into Oregon, picking up I-84 east before crossing back into Washington at Cascade Locks via the Bridge of the Gods. Alternatively, take WA-14 east from Vancouver, Washington, hugging the Washington side of the Gorge the whole way. The WA-14 route adds 20 to 30 minutes but keeps you in Washington and avoids freeway monotony.
There is no practical transit option. A car is required for this destination.
When to Go
Carson Hot Springs operates year-round, and each season has something to recommend it.
Fall (September through November) is the most underrated window. The Gorge’s maple and cottonwood forests turn orange and gold, crowds thin noticeably after Labor Day, and soaking in warm mineral water while autumn color peaks around you is one of those combinations that feels worth the drive on its own. Air temperatures stay mild well into October. For more detail on what to expect across Washington’s seasons, our month-by-month guide to visiting Washington State breaks it down week by week.
Winter (December through February) surprises visitors who’ve dismissed it. Soaking outside in 100-degree mineral water while cold rain falls is a genuinely good experience in a way that’s hard to describe until you’ve done it. The resort is far less crowded November through February, and nightly rates on the rooms and cabins are typically lower.
Spring (March through May) brings wildflowers to the Gorge hillsides and waterfalls running at full volume from snowmelt. It’s a strong season for pairing a soak with waterfall hikes along the Columbia.
Summer (June through August) is the busiest period. The outdoor pools can feel crowded on July and August weekends, and advance reservations become essential rather than optional. Weekday visits in summer are noticeably quieter and easier to plan around.
What to Bring
- Swimsuit and towel (towel rentals are available on-site, but bringing your own is simpler)
- Flip flops or sandals for walking the pool deck
- Cash or card for entry fees and any add-on services
- A change of clothes for after your soak, especially in cooler months
- A water bottle: mineral soaking is dehydrating, and drinking water while you soak makes a difference
Leave expectations for full-service spa amenities at home. The resort has a small snack bar and convenience options, not a restaurant attached to the pools. Eat before you arrive or plan to stop in Stevenson, 10 miles west.
Nearby Outdoor Adventures Worth Adding
The real case for Carson Hot Springs is its location. The Columbia River Gorge and the Wind River Valley put several of Washington’s best outdoor destinations within an easy hour of the pools, making a soak a natural centerpiece for a full day or a long weekend.
Beacon Rock State Park (8 miles west on WA-14): The 848-foot basalt monolith is the second-largest such formation in North America, and the 1.8-mile trail to the summit delivers some of the best open views of the Gorge from the Washington side. The climb is steep and well-maintained, with switchbacks and handrail sections near the top. It’s a solid morning activity before an afternoon soak. Washington’s state parks page has details on recreation passes and current conditions.
Hamilton Mountain Trail (Beacon Rock State Park): A 7.8-mile loop starting from the same trailhead as Beacon Rock, with higher elevation, waterfall views partway up, and open ridgeline at the top. Less trafficked than the monolith trail and more physically demanding. Allow four to five hours.
Dog Mountain Trail (10 miles east on WA-14): One of the Gorge’s most celebrated wildflower hikes, particularly in May and June when balsamroot and lupine cover the upper slopes. The 7-mile round trip gains 2,800 feet with panoramic Columbia River views. Get there by 8 AM on spring weekends or expect a long wait for parking. Permits are required for this trailhead during the high wildflower season.
Wind River and Gifford Pinchot National Forest: The Wind River, running north from Carson into the national forest, offers trout fishing, summer swimming holes, and access to quieter forest trails away from the Gorge’s heavy visitor traffic. For a broader look at outdoor recreation across the state, the outdoor activities section covers Washington’s wilderness options by region.

Where to Eat and Stay Nearby
Staying at the resort: Carson Hot Springs has hotel rooms and cabins on-site. Staying overnight means you can soak during off-peak hours, early morning or late evening, without the drive. The rooms are basic and priced to match. The cabins are a step up in privacy and worth checking availability for.
Stevenson (10 miles west): The Skamania County seat has more lodging options at a range of price points. Skamania Lodge sits on a bluff above the Gorge with Columbia River views, a full-service restaurant, an indoor pool, and access to the Columbia Gorge Interpretive Center just down the road. It’s a meaningful step up in amenities and cost, but it anchors a comfortable two-night trip. For a broader search of lodging across Washington, the hotels section of this site is a good starting point.
Eating: Carson itself is a small community. Rock Cove Kitchen at Skamania Lodge in Stevenson is the most reliable full-service dining option in the immediate area, with Pacific Northwest-focused dishes and Gorge views. There are also several casual spots along Second Street in downtown Stevenson. Plan to eat before or after the soak rather than counting on substantial food options at the resort itself.
Before you go, the plan your trip page can help you pull together logistics for lodging, drive times, and activities across the whole region.
Carson Hot Springs is the right destination for visitors who want to combine an outdoor adventure day with something that slows things down. It’s not dramatic or curated. It’s warm water, a quiet valley, and one of the Pacific Northwest’s great river corridors out the window. For a trip built around Washington’s wild places, that’s exactly enough.
