At La Marette camp-site you are in the kingdom of hill walkers, ramblers and mountain bikers!
No need to look any further for an attractive place to indulge your favourite activity. You can start out from the campsite, with walking boots on your feet, for the assault on Tanargue. This starts with the walk to La Cham du Cros which you have scoffed at since you arrived.
Cyclists have no less of a choice, provided they are reasonably fit.
But unless you set out with your horse and knapsack, you will have to make a little effort to get to the nearest horse riding centre.
The map of “400 walks and horse rides in the Southern Ardèche” can prove very useful for organising all your activities.
