In reply to fodi:
Went there last September -- loads of good climbing within half an hour's drive of Montblanc. Nearest locations are Villanova de Prades (good lively campsite below the crags with all facilities and also timber chalets if you want a bit more comfort), and La Riba. Most of the climbing is on Conglomerate which takes a bit of getting used to. Granite Trad and sport climbing near Poblet monastery -- see pics on my profile. Not in any guidebook (english or spanish).
Cant tell you anything about the hotel, as we stayed at Villa Engracia - Les Masies - L'Espluga De Francoli.
Beautiful area, nice people, great wines and not many Brits, even less nightlife, dont arrive on a Sunday and expect to find any supermarkets open (or restaurants before 9pm)
Wish we were going back this year, but counting the pennies.
