From the El Pati parking, walk down into the valley, passing the El Cargol pillar and El Pati. Cross the valley and make a right at the fork (left takes you to Siuranella Este). After you are deposited at the base of the cliff, walk to the right about 10m, then climb the cliff 3m and turn back the way you came, walking along a small ledge. After 5m you'll turn back to the right and follow a chimney up to the main ledge, emerging under the opening pockets of Hot Knife (direct start). It's about 10 minutes from the car.
