Skwellepil Creek Wilderness Site is a free, user-maintained BC Forest Service recreation site situated on the shore of Chehalis Lake, north of Harrison Mills.

Access requires a 4x4 vehicle via the Chehalis Forest Service Road, and the site is open year-round on a first-come, first-served basis with no host on site.

The campground offers roughly 20 or more sites set among the forest, with picnic tables, fire pits, pit toilets, and a boat launch providing direct access to the lake.

Because it is user-maintained, campers are expected to pack out all waste and leave facilities in good condition. The site can get busy during summer long weekends given its scenic lakeside setting and free access.

Its combination of waterfront camping, boating opportunities, and surrounding trails gives it a feel similar to a provincial park campground, without the fees.
