Square Rock Climbing

Take Broadway to Table Mesa and turn W. on Table Mesa. Follow Table Mesa all the way to NCAR and park at the NCAR lot. Now take the "NCAR Trail" along the nature walk along the rim of the hill. Look for a trail that cuts left and down the hill to some switchbacks. Follow this trail all the way to the water tower and continue left of the tower down to the Mesa Trail. Here, you will come to a junction with a Boulder Mountain Parks info/map board. Take the Mallory Cave Trail up the hill for a nice hike. You will see several signs for climbing access, but stay on this trail. When you come to the junction of the climbing access to Dinosaur Mountain, take a right up the hill, which is still the Mallory cave trail. Keep following the trail until you see a sign for climbing access to "Der Zerkel." You'll see the nice cliffs just up the hill. :)
