What a fabulous invention of nature this isthmus of Penthièvre is! A narrow strip of land cutting through the water, 22 metres long, the isthmus welcomes you to the peninsula in a way that is as strange as it is spectacular - enough to set any poetic mind bubbling! When you arrive by train aboard the emblematic Tire-Bouchon, you can admire the sea from either side of the windows, and you literally have the impression of riding on the water.
