Passo Sella is perhaps the busiest climbing area in the entire Dolomites range and for good reason. Within a few minutes walk exist literally hundreds of multi-pitch routes of all grades and all types (traditional and sport). The majority of the routes catch a fair amount of sun so tend to be dry and climbable most days in the mid summer and fall even during unsettled weather (unlike the North faces and even West faces during some of the wetter seasons).

For organizational purposes, the routes listed in this area include those in the South Western aspects of the group extending from Val Lasties (the valley to the right of Piz Ciavazes) up over Passo Sella and back around the Western side to Passo Gardena. (Piz Ciavezes, all the Sella Towers, Torre delle Mesules). Those looking for the sport climbing area near this pass (Citta Dei Sassi) should look at the Sassolungo section as those routes are on the opposite side of the pass and adjacent to Sassolungo. (The exception here is the sport climbing area Frea which is between Sella pass and Gardena pass but is so close to the Gardena pass that it is listed there rather than in the Sella pass grouping).
