Slovenia has more castles than a country its size has any right to, and most of them are within an hour of each other. What follows are seven that repay the drive in November, when the light is flat, the leaves are down and you can see the shape of the thing you came for.

1. Bled Castle

On a rock above the lake, one of the oldest castles in the country, with a museum inside and a working printing press where you can print your own sheet. The terrace over the lake is the photograph everyone takes, and it is worth taking.

Go early or late. Midday in any month is a queue.

2. Predjama Castle

The one everybody photographs: a castle set into a cave mouth halfway up a cliff, with the cave running on behind it. It has been documented since the 13th century, and it is only a few minutes from Postojna Cave, which makes it a natural pair on a wet day.

3. Celje Old Castle

One of the largest castle complexes in the country, on the hill above Celje, and the seat of the counts of Celje, who were a serious European power in their day. The walls go on and on, the views run up the Savinja valley, and there is a proper museum inside.

Celje itself also has Roman remains, so you can do two thousand years of history on one hill and one town square.

4. Ptuj Castle

A regional museum in a castle above one of the oldest towns in Slovenia, with the Drava below and vineyards outside. The collections include musical instruments and masks, and the view from the walls is the best reason to climb up.

Ptuj is also a thermal spa town, so a castle morning and a pool afternoon is a genuinely good November day.

5. Snežnik Castle

The odd one out: a white manor house in the forests of Notranjska, south of Ljubljana, still furnished as it was left, with a hunting collection and bears in the woods around it. The road there through the Karst forest is half the visit.

Less fortress, more atmosphere. Best in mist.

6. Grad Kamen, Begunje

The ruin in the trees above Begunje na Gorenjskem, near Radovljica. Free to walk to, no ticket office, no café, no queue: just walls, a gate and a forest. Come here when you want a castle without a gift shop.

7. Kostel Castle

Above the Kolpa river on the Croatian border, in the deep south-east, on a rock over the water. Remote enough that you will likely have it to yourself, and the drive down through the Kolpa valley is the most underrated road in the country.

This one is a day trip from Ljubljana, not a stop on the way to somewhere else.

How to do a castle day well

• Check opening days before you drive. Big castles have winter hours; ruins have no hours at all. A November Monday can be dead.

• Pair one castle with one thing that is not a castle. Predjama with Postojna Cave, Ptuj with the thermal baths, Celje with the old town.

• Go for the building, stay for the view. Every one of these is chosen for what you see from the walls.

• Bring cash for small places. Village ticket desks are not always equipped for cards.
