The Holy Cross Mountain Route branches off from the upper section of the Gunnery Creek Trail in Don Getty Wildland Provincial Park. After following the creek valley for several kilometres, the route turns sharply uphill toward the base of Holy Cross Mountain. From there, it climbs through open meadows and loose scree to reach the northeast ridge. The final stretch is a steep scramble with some exposure, but the summit rewards you with panoramic views over the Highwood Range and the wild valleys of the park. It’s a challenging extension of the Gunnery Creek Trail, best tackled by experienced hikers with strong route-finding skills.
