This walk from la Font de l'Orme (Merindol) has been my favourite walk in the Luberon since the 1990's. You reach Pic de Faiendre (598m) in just 1h 15min from the car and continue all the way to the Petite Luberon Ridge (an old Vadois route). From Bastidon du Pradon you take the most impressive descent down from Luberon anywhere (along Serre Long) and you end up getting a little "tast" of the Gorges de Regalon at the bottom, on the way back to the car.
