S'estret is an area of easily accessed crags located just to the south of the beautiful village of Valldemossa (Mallorca, Spain). The various crags offer several different attractions for climbers; a series of pleasantly situated west-facing walls overlooking the road in the valley bottom - Sector Cuarentón; a set of boulders which have been developed with a multitude of problems; and an old abandonded quarry with a big steep overhanging wall with some exceptional routes in the higher grades. In the woods below the main crag the boulders offer some well-shaded bouldering.
