Chamonix Valley is a beautiful walking country with clear, clean air, dark and light pine forests, gleaming glaciers and soaring rocky peaks. Walks are well signposted and accessible either from the valley floor or by cable car (open usually from 15th June to September). All the while discover Chamonix's flowers, birds, wildlife and geology.
Beware of patches of old snow, especially early in the season. In some instances an ice-axe and crampons may be useful; take local advice or check with chamonix.net.
For gear, lightweight boots and shorts are sufficient. Waterproofs are essential and trekking poles useful. Don't forget sunglasses and skin and lip protection. Always carry drinking water and make sure to check chamonix.net for the weather forecast.
