Lumpy’s Epic is a part of the One Mile Lake Area x-country/all-mountain trail system. It is a super technical and challenging trail offering up incredible views of the Green River below, seen as you crest out onto several rock bluffs along its route. On a bluebird day Mt. Currie will be seen clearly in the background, across the Green River. Tight switchbacks, loose rocky sections, rock slabs and super fun descents make this roller coaster of a ride a good time for the advanced to expert rider. This is the longest trail in the One Mile Lake Area and a classic Pemberton ride, making it a must do trail for the experienced mountain biker visiting the Pemberton Valley.
There are several ways to access Lumpy’s Epic, but the most popular route is to take the Sea to Sky Trail over to Overhill. Pedal up Overhill for less than 50 m and turn right onto Nairn-One Mile, following the signs for Lumpy’s. The official trailhead for Lumpy’s is found about 1 km down Nairn-One Mile and is well signed. Take the trail for Lumpy’s and continue to climb up several steep and long switchbacks. The route up the switchbacks gets steeper as you near the top and becomes much more rooty and rocky. Lumpy’s will eventually pop out at the well-marked junction for K2. Continue right, along Lumpy’s and down a section of rolling slab. The slab gets steeper and more challenging near the end of this awesome section. Descend with caution when the slab is wet. The route that follows the slab will include more of the same. The rider will be greeted with more slab options, roots and rocks, steep ups, and short technical downs. This is exactly what the advanced trails in the area are like; so much fun! The final descent will spit you out onto a horse trail, take a left and follow the trail back to the One Mile Lake parking area or to the Pemberton Village.

Park at One Mile Lake and ride the Sea to Sky Trail to Overhill. Pedal up Overhill for about 50 m to the sign pointing to Lumpy’s. Head right at the sign along the Nairn-One Mile trail – this section of trail is also referred to as Lumpy’s which may confuse the rider when referencing the map. Continue to climb up the Nairn-One Mile trail for about 1 km until you reach the official trailhead for Lumpy’s Epic. It is well-signed.
