Less than 2 hours on the train winding steeply up from Nice, a 4 wheel drive and an all day hike took us into la Vallee des Merveilles beneath the summit of Mont Bego in the National parc du Mercantour. A glaciological showcase, guided and protected, the focus was on the Bronze Age art (petroglyphs) and ancient graffiti engraved into the blue green, violet and burnt orange rocks all dotted with a fluorescent green lichen. Chamois, Marmots running around and vultures circling too. Amazing day.
