Waterfalls dominate the Jura region, and the Cascades du Hérisson is a good place to start, not least because all the signs seem to point you in that direction. Start by climb up and above the dramatic main falls of L’Éventail and the Le Grand Saut. Neither of these has a plunge pool but if you continue further through woodlands on the marked trail you will come to the Le Gour Bleu, a perfect plunge piscine set in a wooded glade with beach and a waterfall. You can climb up and behind the curtain of rushing water and explore behind the falls too – a real treat. Follow the D678 from Lons-le-Saunier (Lat Long 46.6147, 5.8605). Lac du Val is on the road to the visitor centre for the falls and is also good for a longer swim.
