The Tête Rousse Hut (French: "Refuge de Tête Rousse") is a mountain hut in the Mont Blanc massif in the French Alps.
 It is located beside the Tête Rousse Glacier at an altitude of 3,167 m. Owned by the Club Alpin Francais (CAF), it is normally reached after a multi-hour climb from Nid d'Aigle, the highest stop on the Mont Blanc Tramway.
 It is commonly used by mountaineers attempting to climb the normal (Gouter route) to the summit of Mont Blanc.
 Staying here, rather than continuing to the higher Gouter Hut adds an extra 2–3 hours to the ascent of Mont Blanc, but is less cramped than the latter and also avoids having to climb the dangerous 'Grand Couloir' later in the day when the risk of injury from stonefall is at its greatest.
Chloé Graftiaux (18 July 1987 in Brussels, Belgium – 21 August 2010 in Courmayeur, Italy) was a Belgian sport climber, who fell to her death on the 3773 m Aiguille Noire de Peuterey in the Mont Blanc massif, aged 23.
The Tour Ronde (3,792 m) is a mountain in the Mont Blanc massif of the Alps, situated on the border between France and Italy.
 It is a prominent mountain, some 3.5 km north-east of Mont Blanc, but is effectively part of a continuation of the south eastern spur of Mont Maudit (l'Arete de la Brenva) which forms a frontier ridge between the two countries.
 It is easily accessible to mountaineers and provides not only a very good viewpoint from its summit of the Brenva face and the major peaks on the southern side of Mont Blanc, but it also offers a popular introduction to alpine climbing of all grades, including a north face ascent.
The Torino Hut (Italian: "Rifugio Torino" ; French: "Refuge Torino") is a high mountain refuge in the Alps in northwestern Italy.
 Located near the border with France, it is about 15 km southwest of Mont Dolent, the tripoint with Switzerland.
 The refuge is in the Mont Blanc massif above the town of Courmayeur in the Aosta Valley, Italy.
 It can be most easily accessed from the Italian side by the Skyway Monte Bianco cable car from La Palud in Courmayeur, with a change at the Pavilion du Mont Fréty.
 It can also be reached from Chamonix via the Aiguille du Midi, either by cable car which crosses the massif, or by a long crossing of the Glacier du Gèant.
 The refuge lies nearly directly above the 11.6 km Mont Blanc Tunnel, which passes deep underground, and connects Courmayer to Chamonix.
Mont Blanc du Tacul (4,248 m) is a mountain in the Mont Blanc massif of the French Alps situated midway between the Aiguille du Midi and Mont Blanc.
Refugio Elisabetta (or Refugio Elisabetta Soldini Montanaro to give it its full, but less well-used name) is a refuge in the Italian Alps at an altitude of 2,195 m, which provides a convenient overnight stage for walkers undertaking the Tour du Mont Blanc.
 It is located 3 km north-east of the Col de la Seigne, at the south-west end of the Mont Blanc massif, and provides good views of Mont Blanc and the Aiguille Noire de Peuterey.
 Because of its popularity, plus the fact that there are no other huts along this part of the Tour du Mont Blanc, walkers are advised to book in advance during the peak periods in July and August.
The Aiguille Blanche de Peuterey (4,112 m) is a mountain of the Mont Blanc massif in Italy.
 It is considered the most difficult and serious of the alpine 4000-m mountains to climb.
The Aiguille Noire de Peuterey (3,773 m) is a mountain of the Mont Blanc massif in Italy, forming part of the Peuterey ridge to the summit of Mont Blanc with its higher neighbour, the Aiguille Blanche de Peuterey.
The Mont Blanc massif (French: "Massif du Mont-Blanc" ; Italian: "Massiccio del Monte Bianco" ) is a mountain range in the Alps, located mostly in France and Italy, but also straddling Switzerland at its northeastern end.
 It contains eleven major independent summits, each over 4000 m in height, and is named after Mont Blanc (4808 m ), the highest point in western Europe and European Union.
 Because of its considerable overall altitude, a large proportion of the massif is covered by glaciers, which include the Mer de Glace and the Miage Glacierthe longest glaciers in France and Italy, respectively.
The Chablais Alps are a mountain range in the western Alps.
 They are situated between Lake Geneva and the Mont Blanc Massif.
 The Col des Montets separates them from the Mont Blanc Massif in the south, and the Rhône valley separates them from the Bernese Alps in the east.
