Sulphur Warm Springs

## Overview Sulphur Warm Springs is a secluded, natural warm spring tucked into the forested mountains near Darrington in Snohomish County, Washington. With a water temperature typically around 90°F, it falls on the cooler end of the hot spring spectrum — more accurately described as a warm spring — but its intimate setting and remote feel make it a rewarding destination for hikers and hot spring enthusiasts alike. The spring feeds a small, hand-dug soaking pool that comfortably fits about two adults (or two adults and a small child). Because it isn't a developed resort or a widely publicized public hot spring, Sulphur Warm Springs sees relatively few visitors, lending it a peaceful, private atmosphere that's hard to find at more popular soaking spots in the Pacific Northwest. The sulphur content gives the water its name and a faint mineral smell characteristic of geothermal springs in the region. ## Directions Sulphur Warm Springs is located near Darrington, WA (GPS: 48.295099, -121.408016). The hike to the spring is approximately one mile along a forested trail, followed by a few additional minutes of walking. 1. **Trailhead access:** Navigate to the GPS coordinates above, which will bring you to the general area near the trailhead outside Darrington. 2. **Follow the trail:** The path is roughly one mile long and passes through beautiful old-growth forest. The terrain is relatively gentle and not very steep. 3. **Stay alert for trail markers:** Because Sulphur Warm Springs is not heavily trafficked, the trail can be faint or overgrown in places. Pay close attention to the path and watch for any informal markers or cairns left by previous visitors. 4. **Cross the log bridge:** After about a mile, you'll encounter a log bridge. Cross it and continue a few more minutes along the trail. 5. **Arrive at the spring:** The small soaking pool will be near the end of the trail. *Note: Trail conditions may vary seasonally. The route is not always well-maintained, so plan accordingly and allow extra time if needed.* ## What to Expect **The Soak:** The soaking pool is small and natural — expect a rustic, undeveloped experience. The water temperature hovers around 90°F, which is pleasantly warm rather than steaming hot. The sulphur-mineral water has a mild smell typical of geothermal springs. **The Hike:** The roughly one-mile trail is the real highlight of the trip. It winds through stands of impressive old-growth trees and offers a peaceful forest walk even if you're not planning to soak. The grade is gentle, making it accessible to most fitness levels, though the trail can be faint in spots due to low foot traffic. **Privacy & Crowd Levels:** Because Sulphur Warm Springs is off the beaten path and not commercially developed, you'll often have the spring to yourself or share it with only a handful of other visitors. This makes it an appealing option for couples seeking a quiet retreat or anyone who prefers solitude over the social scene at larger hot springs. **Best Time to Visit:** A daytime visit is strongly recommended. The trail is not well-marked, and navigating it after dark would be difficult and potentially unsafe. Spring through early fall generally offers the best trail conditions, though the spring flows year-round. **What to Bring:** Wear sturdy footwear suitable for an uneven forest trail. The log bridge crossing can be slippery, so take care when crossing. There are no facilities, changing rooms, or services at the spring — come prepared for a fully backcountry experience.
