Go north on Macleod Trail from Shawnessy Blvd or Stony Trail. Take the turnoff to Bannister Road SE, and take it north to the entrance of Fish Creek Provincial Park.
From the Glennfield Day Use area parking lot, take the path that follows the south bank of Fish Creek eastward. Keep a look through the bushes to the north. When you can see the yellow cliffs, take the informal but well-worn path and follow it to the cliffs.
From the gravel beach, you can see the outcrop on the other side of Fish Creek. Don't cross Fish Creek - it can be fast and deep. There is no access from the north side either. Mind the nude sunbathers on summer days.
