This may or may not have been a place to TR in the decades past, if so, not recently and Barrier Bluff Guidebook author Kelly Tobey was not aware of climbing done anywhere in this area found simply across the highway from Barrier Bluffs.
The area has two separate bluffs: the slabby north face as you drive up the road and the the overlook above and west of the parking area.
The overlook above the parking was checked out in the summer of 2015. One route was lead on gear at this time- an unnamed obvious crack seen from the parking area.
To get to the Parking Lot area, first drive Highway #40 in Kananaskis and turn west onto the road that leads to the Barrier boat launch, found across from the Barrier Bluff parking area. Pass through the T-intersection and up the windy hill and into the parking lot. The cliff is dead obvious to the west, but to make the approach in 5-10 minutes follow this: from the NW edge of the parking, go to the posted sign. Hike directly west into the woods dodging some bush. Cross over a well-trodden hikers path and continue west and up. A somewhat trail emerges here and there and one on a tiny scree slope the cliff is only moments away. Hike to the corner of the cliff, and follow it along the base. Helmets are mandatory common sense in this area.
Unnamed Crack(5.7), bring a size #4-6 nut for a ground belay directly under the line. Suggested gear could range from small tri-cams and med-large nuts but mostly tri-cams only work. Sizes range from #.75-#4/5. The climb is about 15-20m in length and ends at a good tree directly above the exit steps. Rap or walk off. We tried unsuccessfully to TR the slab-groove about 10m to the north.
top-rope(5.9), in the 15-20m range is a super fun top-rope problem found near the left end of the cliff and starts up and right of a huge bushy tree. Start in a v-shaped groove to a ledge. Layback cool slab hold to surmount the first overhang by moving up and left and straight up to big roof. Crank up the wildly fun rock spike to top out, move up to the tree.
