You can access this trail from the top of West Kelowna Rd or as part of the larger network of trails in Rose Valley Park.
From the top of West Kelowna Rd, enter the park and follow the service road for 100 meters and take the north fork. Before the next steep climb (you'll see it), take a left and in 50 meters look for the singletrack on your right and it starts your switchbacks.
Your work is rewarded at the top with some great views of the Okanagan Valley and some rolling singletrack down to Rose Valley Lake. Once you hit the lake, a left takes you along the shore and back to Swamp Donkey Trail to climb back out to the trailhead.
