Markets
Big one in Apt on Saturdays, small farmer’s market in Coustellet on Sunday mornings. Coustellet also has a cash-point machine. Don’t miss the boucherie on the main street. Isle sur la Sorgue has a flea market most days. For more information check out this list of markets.
Villages
Don’t miss Oppede (nice little café), Lacoste (Marquis de Sade’s castle), Bonnieux (nice bars), Gordes (biggest in the area, quite touristy though)and Roussillon (ochre village). Further afield is Vaison La Romaine, a huge Roman archeological site. Also Aix-en-Provence is worth a trip. Finally the fort at Buoux is very interesting, has great views and a nice restaurant (La Loube).
Wine
After all, let’s be honest, this is the real reason you are going. There are tens of vineyards that have tasting sessions (degustations). The nearest ones are Domaine de la Citadelle and Domaine de la Royere, but as you drive around you will see lots more. One I would recommend is on the D3 road between Bonnieux and Apt (on the left coming from Bonnieux) is Le Mayol, who are very helpful and patient. If you wanted to make a day of it, the Chateauneuf-du-Pape region north of Avignon includes Gigondas and Vacqueras wines, all of which are excellent and probably a cut above the local plonk.
Outdoor stuff
There are two mountain bikes at the house for burning off those large lunches.
The walk to the top of the Luberon is well worth it for the views. Look on the blue maps in the bookcase at the house for options.
We often go for the a walk through the Gorges de Regalon, off the road between Cheval Blanc and Merindol, on the other side of the Luberon.
Driving to the top of Mount Ventoux will take you to the place with the highest-recorded wind speed ever.
