Drive from Margalef towards Lleida for 1.6km (km 6.2) and turn right onto the road to «El Pantà» (reservoir). After 1.7km, turn right again onto a surfaced track that descends towards the river. Drive a further 250m, cross the bridge and park at the right (P8, 2km). Take the path that follows the riverside for 400m until a cross path (photo 1). Take the path shown in the photo 1. Walk 30 meters and turn left onto a path that enters the valley. Along the following 200m you will see a couple of paths to the right hand side, ignore them and continue straight. Always follow the path that enters the valley and, after 15min walking (from the parking), find Totxo de la Catedral on the left hand side.
To go to Purgatori, pass Totxo de la Catedral, a few meters ahead the path splits. Take the left path and walk 5 minutes up to reach the sector.
