Porrentruy suits couples and small families after a walkable old town with a castle in the Ajoie, the northernmost part of Canton Jura. Expect cobbled streets, Baroque town houses and the Jurassica Museum. Getting here takes time, though: allow about 1 hour 40 minutes by train from EuroAirport.
Porrentruy is a small French-speaking town in the Ajoie, the northernmost part of Canton Jura, and was for centuries a residence of the prince-bishops of Basel. The old town is compact and easy to walk, with cobbled streets, Baroque houses with towers and courtyards, the town hall, the Jesuit church and the Hôtel-Dieu, an 18th-century former hospital that now houses a museum and an old hospital pharmacy. The castle's oldest part is the 13th-century Réfous Tower. The Jurassica Museum covers marine fossils and minerals and has one of the oldest botanical gardens in Switzerland. The homes are in and around the town, mostly sleeping about four.
An educational trail near the village shows dinosaur footprints from the time, millions of years ago, when the Jurassic Sea reached this far.
Known for its grottos and for the Préhisto Park, which takes dinosaurs as its theme.
A town set on the river Doubs, worth adding to a stay in Porrentruy for a day with a different feel.
Reached on the local Chemins de fer du Jura line from Porrentruy; the ponds of Bonfol and Vendlincourt are worth a walk.
EuroAirport Basel-Mulhouse-Freiburg is the nearest airport, about 1 hour 40 minutes away by train. Porrentruy station is on the Delle to Delémont and Biel Regio Express line and the S3 of the Basel S-Bahn, and drivers use the A16 motorway. The town is small enough to explore on foot, so a car is optional.
Yes. The old town is small and easy to explore on foot along cobbled streets, and a dedicated walking tour around Porrentruy is available, so the car can stay parked once you arrive.
Partly, and for free by day. The castle courtyard and the 13th-century Réfous Tower are freely accessible during the day, and the Secret Circuit gives you a badge to explore unusual corners of the castle and old town.
Near Courtedoux, on the educational trail In the footsteps of the giants, with footprints from when the Jurassic Sea reached the area. Back in town, the Jurassica Museum shows marine fossils and minerals.
Look out for totché, described as the only savoury cream cake in Switzerland, and saucisse d'Ajoie, a cumin-scented sausage, alongside Tête de Moine cheese.
