Meet at Eygliers Gare, in the Marmot Trail parking lot, opposite the Auberge d'Eygliers (RN94).
You'll join one of the teams positioned at strategic points so you can see the whole site. No special knowledge is required. Please remember to bring binoculars if you have them, a pencil to write things down and a camera to keep a souvenir of the great encounters you'll have.
You don't need to be a specialist to take part!
