Description: While white water rafting is possible, it tends to be an early spring activity as this is when the river levels are much higher and the flow of water greater. During the long, hot summers the river levels lower considerably making canoeing/kayaking much more suitable/safe for families. routes etc? The most popular route is to meander the 8km stretch downriver from Collias to the World Heritage site of the Pont du Gard ? a truly spectacular way to arrive at this awesome site!
