The route into Lyons Lake is a fine walk/hike, but has been out-of-sight-out-of-mind for many years. We have hiked and biked to the end of the lake a few times and we returned to hike it again this fall. We were surprised that the old backroad had seen lots of traffic, and had been widened, cleared, and was a bit muddy for the first two kilometers. We could hear logging underway on the eastern sideslopes below the Knouff Lake Road, but we encountered no trucks on our track.
The old track was still there, but it started closer to Lyons Lake. The moderate hike to the end of Lyons Lake and back is 10km. Lyons Lake is a quiet and picturesque spot between wooded ridges, but the grasslands of Sullivan Valley stretch off to the north.
The double track along the west shore of Lyons Lake is the attraction. At the end of the lake are fences separating private land off the Vinsula-Knouff Road. The Lyons Lake route is a simple out-and-back.
To hike this route, turn off the Sun Peaks Road to the Heffley Dump. Pass the transfer station and look for a sideroad going into a gully on your right. Park up the Dump Road a short ways past the junction, then follow the double track through the gully. At an intersection 2km up, take the road that goes left to the lake. Turn around at the end of the lake and retrace your steps.
This route is also a good snowshoe or mountain bike route. The roads going to the right climb up the hill, eventually joining the Knouff Lake Road. Lyons Lake is the spot, though, for a quiet lunch before returning to the trailhead.
