The Sierra de Montsant comprises excellent climbing on high-quality conglomerate. In fact, Lynn Hill told me that this was her favorite climbing area in Spain. It's close to Siurana and mostly has one-pitch climbs.
Getting There
From Reus, drive toward Cornudella de Montsant on C242 (the same approach as for Siurana.) From Cornudella, take TV7021 fro 8 km to Morera de Monsant. Take the right-hand fork through the village, turn right at the Place del Priorat, then the second right to "Carrer de la Banna" to its end, turn left, and park . Approach: follow trails to Barrots
