Cerdanya by campervan in autumn: 3 days between Spain and France
Cerdanya is the only Pyrenean valley split in two by a border that today is little more than a road sign — you cross it without noticing. This 3-day route leaves from Mataró, runs through the Cadí tunnel and loops around both sides of the valley — Catalan villages, the Llívia enclave and French Cerdagne — while autumn turns the meadows gold and dusts the peaks with the season's first snow.
It's the perfect time of year for the California: mountain roads and the narrow streets of Llívia or Mont-Louis suit it perfectly, and the parking heater turns cool October nights into the only reason to stay in the van a little longer.

Day 1 — Mataró to Bellver de Cerdanya and Martinet, afternoon in Puigcerdà (160 km)
Leave Mataró for the Berguedà and the Cadí tunnel — almost 5 km that save an entire mountain pass and drop you straight on the other side of the Pyrenees. First stop in Bellver de Cerdanya, with its main square and the church of Sant Jaume, then a stroll around Martinet by the Segre river.
In the afternoon, Puigcerdà: a walk around the estany, the Gothic bell tower — all that's left of the original church — and vermouth on a terrace overlooking the whole valley. Overnight at the Puigcerdà motorhome area or a campsite by the Segre in Bellver, around €10–25.
Day 2 (morning) — Llívia, the Spanish enclave inside France (15 km)
A few minutes from Puigcerdà, Llívia is a geographical oddity: a Spanish town entirely surrounded by French territory since the 1659 Treaty of the Pyrenees, when Spain ceded 33 villages in the Roussillon but Llívia was spared because it held the status of a town rather than a village. It's worth stopping at the Pharmacy Museum, the oldest working pharmacy in Europe, with ceramic jars dating from the 15th century.
From Llívia into French Cerdagne there's nothing to declare: the border is just a sign by the road, no checkpoint, no customs — you cross without even noticing.
Day 2 (afternoon) — Mont-Louis, the Odeillo solar furnace and the Dorres hot pools (35 km)
From Llívia, ten minutes brings you to Mont-Louis, the highest of Vauban's fortress towns in France, with intact ramparts and a full walk around the walls worth taking. A few kilometres on, the Odeillo solar furnace in Font-Romeu surprises anyone seeing it for the first time — a nine-storey parabolic mirror that concentrates sunlight powerfully enough to melt metal.
The day's last stop is the Dorres hot pools, open-air thermal baths with views across the whole valley — best reached at sunset, when the steam mixes with the low light and the cold air outside makes the water feel even warmer.
Day 3 — The camí dels Enginyers or Talló, then back via Bagà and the Cadí viewpoint (160 km)
Take the last morning slow: the camí dels Enginyers, an old railway line turned flat, easy walking path, or a walk across the meadows to Talló and its Romanesque church in the middle of the Cerdanya plain. Head south again around midday.
Before the Cadí tunnel, it's worth stopping in Bagà, with its medieval old town, or at the Cadí viewpoint for one last look at the range before dropping down towards Mataró.
Frequently asked questions
Is crossing into France a problem?+
Not at all — the vehicle's paperwork stays in the glovebox and that's all it takes. There's no customs post or border check in Cerdanya; you pass from one country to the other without noticing.
How does the mileage compare to what's included?+
About 320 km in total, round trip from Mataró included — within the 100 km/day included in a 3-night rental, and easy to extend if you go a little over exploring the French side.
Is it already cold in autumn?+
Nights get cool at altitude, especially from October, but the parking heater sorts that out in five minutes without draining the engine battery. And the autumn colours — red beech and golden poplar — more than make up for an extra blanket.
