South Coldwater Trail

South Coldwater Trail (#230A) is a ridge walk above Coldwater Lake in Mount St. Helens National Volcanic Monument. The route leads you through willow forest and into the scarred, ash-covered backcountry where 1980 blast-era logging machinery and toppled timber still mark the landscape.

Expect the trail to follow a steady climb from the Coldwater Lake side toward its junction with Coldwater Trail #230. Along the ascent, the trail passes recognizable remnants such as a bulldozer and a mangled yarding tower about a mile from the trailhead.

For early/late-season hikers, meltout can happen earlier on low elevations and later at higher points; snow can persist in some spots on north-facing slopes. The trail can also have downed trees, washouts, and/or landslides depending on recent impacts.

Wildlife is commonly present late spring, and the area can be frequented by elk. If you’re out in warm weather, plan extra water because potable water isn’t available at the South Coldwater trailhead site.

There’s day-use access through the South Coldwater Trailhead. Parking availability may be limited when State Route 504 gates are closed; one alternative described is parking at the Hummocks Trailhead and walking up the road to reach the South Coldwater Trailhead area.

On-trail rules for dogs: dogs are allowed on a 6-foot leash and must stay on the trail. Horses/stock, bicycles, and motorized use are prohibited on 230A specifically.
