Located on a tributary of the Clearwater River in western Montana, Placid Lake State Park is a water-lover’s paradise. Just a short drive from Seeley Lake, this 31-acre park offers smooth water for skiing, excellent trout fishing, and a quiet, forested campground, making it a favorite summer destination for families and anglers.

Smooth Waters

Protected from strong winds, Placid Lake is renowned for its calm surface, perfect for water skiing and wakeboarding.

Angler’s Choice

The lake is a prime spot for trout fishing, home to rainbow, cutthroat, brown, and bull trout, plus kokanee salmon.

Forest Camping

Forty campsites nestled in the trees offer a classic Montana camping experience, with both electric and primitive options.


Lake Life

Placid Lake is the heart of the park. Its boat launch and dock are busy all summer with boaters and paddlers. The swimming area offers a cool respite on hot days. Because it’s known for “smooth water,” it typically attracts water skiers early in the morning and evening when the lake is like glass.

Hike-Bike Camping

Uniquely, the park features a dedicated Hike-Bike campsite with bicycle racks, repair tools, and charging outlets, catering specifically to long-distance cyclists touring Montana.

Camping and Amenities

The campground features 40 sites, 17 of which have electricity. While it feels rustic, amenities like flush toilets, showers, and firewood sales make for a comfortable stay. Interpretive panels around the park tell the story of the area’s early logging history, adding a touch of education to your visit.
