Four getaways with a night away and three day trips from Girona for 12 October, the Pilar and National Day: the Penedès and Priorat after the harvest, the Cité in the canal's last month, Rupit, Montsoriu with chestnuts, Ullastret and Montserrat from above.
Map

In early October the Penedès harvest has just ended and the cellars show the new musts. The hotel serves its menu on the eve of holidays, so on 11 October too: book a table with the room.

After the harvest, the Priorat vines begin to change colour, and the reservoir kayak opens on autumn weekends. The 4x4 route is a single vehicle per departure: on the long weekend, book it before the room.

October is the last month of the Canal du Midi boat, which sails until the end of the month. 12 October is not a holiday in France, so the Cité has fewer people than in spring and sleeping inside works out better.

With the first autumn rains the Salt de Sallent runs with water again and the Collsacabra oaks begin to turn gold. For the crossing to Tavertet, arrange the return with the tourist office before setting out.

In October Viladrau already cooks with its chestnut and Montsoriu castle opens its weekend and holiday guided passes. The door closes when the visit starts: arrive with margin and book castle and lunch.

In October the Iberian city of Ullastret is toured without summer's heat, and under-16s go in free. The Peratallada Medieval Fair falls in early October; by the Pilar the village is already quiet.

The Sant Jeroni circuit is in season, from October to May, with clean air for seeing the Pyrenees from the summit. The Aeri leaves from the lower station; check the autumn timetable, which changes with the season.
Questions
Few. The Santa Fe beech wood changes from mid-October to mid-November, depending on the year.
It is three hours each way: better with at least one night.
Not especially: 12 October is not a holiday in France.
