In the 1st century AD, the Romans harnessed the abundant water supply of the Alzon River, the source of the Eure River, located in a small valley at the foot of the city. It is here that the water begins its long journey (over 50 km) to Nîmes via an aqueduct, the most spectacular part of which remains the Pont du Gard, a UNESCO World Heritage Site, spanning the Gardon River. The Eure Valley is a must-see destination for walks for both the residents of Uzès and tourists.

Gorges du Gardon Biosphere Reserve. The Gardon is a river in the French region of Occitanie. It flows beneath the Pont du Gard. The aqueduct is one of the best-preserved Roman structures in all of Europe. Magnificent, imposing, and truly ingenious.

A beautiful loop from Collias. However, the "lower" section will be much more interesting than the "plateau" (T3). There are still a few tricky sections to note in the lower section (T2).

Access is only available during certain periods of the year, due to the conservation of the small inhabitants that inhabit the area. The cave is open from August 16th to November 14th, and from March 16th to April 30th. Bring a good flashlight, as the crossing can take approximately 5 to 10 minutes. This cave is nothing more than the former underground passage of the Gardon River. Accessible to all, be careful, however, once you have crossed, you will be close to the cliff on the other side. The path beyond (T2/T3) can be daunting for some people. Don't hesitate to turn back if you have any hesitation.

The source that was channeled by the Romans via a long canal and the Pont du Gard to Nimes.

Due to the very steep climb, once the cave is passed, over rocks with places where even steel handrails had to be placed, this walk cannot be classified as “easy for every walker”.
