Seen from Le Signal Forbes trail, the Mer de Glace ("Sea of Ice") glacier emerges from the Mont Blanc massif below the Needles of Chamonix. We hiked the Grand North Balcony from Plan de l'Aiguille to Montenvers (4.3 miles one way with 2000 feet vertical ascent and 700 ft descent), above Chamonix, in France, Europe.
