The longest trail in the One Mile Lake area, Lumpy’s Epic is a classic Pemberton cross-country ride. If wide open high-speed flow trails are your thing, Lumpy’s might not be your best choice; if you are into the more technical side of mountain biking and aren’t afraid of getting some exercise, however, then this trail is for you.

Beginning at One Mile Lake, head south on the Sea to Sky Trail toward Nairn Falls Campground for a short distance before following signs for Lumpy’s, which begins heading up the south side of Signal Hill. This first section is made up of tough technical climbing that will get the heart pumping and challenge the most advanced enduro riders. After about 1.5 kilometers the trail crests the top of the hill and the iconic peaks of Mount Currie that dominate the Pemberton skyline come into view.

The next 1.5-kilometer section is predominantly undulating, technical, bumpy singletrack with a healthy portion of rock-roll features. The route follows the edge of the rocky bluffs overlooking the Green River as Mount Currie looms large just across on the other side. After about 3 kilometers the trail begins to descend the northeast side of the hill toward the river, passing by a Provincial Heritage Site where a small Lil’Wat Nation village was once located. Here, the villagers would use smoke signals when visitors arrived that would signal for canoes to ferry across the river, which is how nearby Signal Hill acquired its name. The descent down to the river is fairly straightforward and enjoyable, and a few steeper corners require some attention. A left turn at the bottom leads alongside Pemberton Creek to a bridge. Go left after crossing the creek, cross back again on another bridge about 100 meters upstream, and follow the walking trail back to One Mile Lake and the trailhead.
