The massive and impressive hole of Twll Mawr is famous for its hard routes but a few more amenable multi-pitch sport routes have now been added increasing its appeal to lesser mortals. Although they are fully bolted, the location and atmosphere mean that they should be regarded as adventurous sport climbing. Approach (see map on page 60) - Follow the main track through the upper quarries, to the dip by Dali's Hole. Head over a gate on the right and down towards Rainbow Walls, go down one level and follow this leftwards towards Llanberis Pass. At its end take the tunnel and right fork into Twll Mawr (routes 2-3 start from here). To reach the base of routes 4-6 carry on and then scramble down into the depths of the giant hole. For Combat Rock just head along the main track through the Watford Gap until the giant hole is visible on your left. Guidebook page 66.
