Walk down to the lakeshore path from the day use parking lot and turn right. This trail leads through the group campsite and past the CCC kitchen shelter. The trail continues around the northern and western shorelines. The North Star wildfire in 2015 made its mark on this area, but many of the trees survived and there is new growth. Wild roses and other flowers scent the air.
After about 0.7 mile there’s an unmarked junction. The left fork appears to be the mapped trail, but due to fallen trees and brush, it’s a little hard to navigate. The right fork is a clearer path; it goes uphill and around a few bends before descending to the lakeshore and passing over a couple of footbridges. Look for evidence of beavers in the swampy areas.
If you’re lucky you’ll see loons diving in the placid waters and hear their eerie calls. Near the south end of the lake, you’ll pass a marked junction with the Swan Butte Trail (this spur adds 0.5 mile each way). However, fallen trees may make access difficult.
The Swan Lake Trail ends at Scatter Creek Road. Turn left and walk the camp road back to the day use area.
WTA Pro Tip: Drinking water is available in the Swan Lake Campground. Bring your swimming togs for a dip in the lake after your hike.
