Hiking Merrill Lake Conservation Area - Old Growth Loop Trail

Merrill Lake Conservation Area is a seasonal campground that includes a short and sweet loop trail around a lake. Along the way are 10 interpretative signs that supplement what hikers see around them. 

The trail is on the east side of the lake, at the boat ramp parking lot. Walking this family-friendly path makes for a casual, low-key outing, and includes four benches spaced along with way for resting.

Spared from the axe, visitors will see old-growth Douglas Fir and Western redcedar. The lake was formed by the Mount St. Helens ‘Cave Basalt Flow’ 1700 years ago which blocked part of the Kalama River. The Department of Natural Resources maintains the trail.

WTA Pro Tip: Save a copy of our directions before you leave! App-based driving directions aren't always accurate and data connections may be unreliable as you drive to the trailhead.

Getting There

From Woodland, take Highway 503 east and travel about 27 miles. Just before reaching the
town of Cougar, turn left onto USFS Road 81 (you’ll see a sign for Merrill Lake and Kalama Horse
camp) and travel north about 3.5 miles; the campground access road will be on the left.
