From Calgary, drive 83 kilometers west of Highway 1 and take the Exshaw exit. Follow Highway 1X north for 4.3 kilometers and turn left onto Highway 1A. Continue 11.2 kilometers west to the signed Grotto Mountain trailhead on the right.
This trail leads up a creek bed into a narrow canyon enclosed by imposing gray limestone walls. If you've got very sharp eyes, you may also spot a couple of 500 to 1,000 year-old native Indian pictographs.
