A wonderful place to spend the night and visit Porrentruy. Electricity available (Swiss sockets). Payment by Twint or in cash in a small chalet behind the castle.

Very nice place to stand for visiting castle and town. Electricity available, plug adapter required. Weird system to pay has not worked for me and have not seen anyone.

Fantastic location. Correction to allowed camping times: parking lot behind castle as mentioned, on the grass field in front of castle: 24/7.
