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. The official first ascent of Mont Blanc du Tacul was by a guideless party comprising Charles Hudson, Edward John Stevenson, Christopher and James Grenville Smith, E. S. Kennedy, Charles Ainslie and G. C. Joad on 8 August 1855. However, Courmayeur guides may have already ascended the peak during their attempts in 1854 and 1855 to force a way up Mont Blanc from the Italian side.

The Aiguilles du Diable (literally "Devil's Needles", German: Teufelsspitzen) are a group of five rock needles, all over 4,000 metres high, on the southeast arête (also called the Teufelsgrat or Devil's Ridge) of the Mont Blanc du Tacul. The pinnacles lie within the French part of the Mont Blanc Massif in the departement of Haute-Savoie. The highest needle is L’Isolée (4,114 m), followed by Pointe Carmen (4,109 m), Pointe Médiane (4,097 m), Pointe Chaubert (4,074 m) and Corne du Diable (4,064 m). The first needle to be climbed was Pointe Carmen in 1923 which was conquered by Brégault, Chevalier and De Lépiney. In 1925 the others were first climbed: initially L’Isolée by Antoine Blanchet and Armand Charlet, then Corne du Diable and Pointe Chaubert by Armand Charlet and Jean Chaubert. The last to be ascended was Pointe Médiane by Antoine Blanchet, Jean Chaubert, Armand Charlet and Devouassoud. The first time all the needles were climbed in a single expedition was in 1928 by the Americans, Miriam O'Brien and Robert L. M. Underhill with Armand Charlet guiding them. Today a crossing of the Aiguilles du Diable is usually done as a rock climbing tour, which, in summer, avoids almost any contact with snow. The overall difficulty is assessed as "difficult" on the SAC scale and climbing grade V+ on the UIAA scale.

The Cosmiques Hut (French: Refuge des Cosmiques) is a mountain hut in the Mont Blanc massif in the French Alps at an altitude of 3,613 m (11,854 ft). It is a large structure capable of accommodating 148 mountaineers. It was constructed in 1990 on a rock promontory situated between the Col du Midi and the base of the Cosmiques Arête which descends southwards from the Aiguille du Midi. It gives access to a number of classic alpine mountaineering routes, and has proved to be extremely popular with mountaineers, so much so that in the summer months prior booking a few days beforehand is essential in order to secure a bed. The Hut is wardened between mid-February and mid-October. In winter the nearby Abri Simond Hut is left unlocked, although this has no cooking facilities, heating or water.

The Grand Capucin (3,838 m) is a rock pinnacle located underneath Mont Blanc du Tacul in the Mont Blanc Massif in Haute-Savoie, France.

The Aiguille du Midi (French pronunciation: ​[eɡɥij dy midi]) is a 3,842-metre-tall (12,605 ft) mountain in the Mont Blanc massif within the French Alps. It is a popular tourist destination and can be directly accessed by cable car from Chamonix that takes visitors close to Mont Blanc.

The Mont Blanc Tunnel is a highway tunnel between France and Italy, under the Mont Blanc mountain in the Alps. It links Chamonix, Haute-Savoie, France with Courmayeur, Aosta Valley, Italy, via the French Route Nationale 205 and the Italian Traforo T1 (forming the European route E25), in particular the motorways serving Geneva (A40 of France) and Turin (A5 of Italy). The passageway is one of the major trans-Alpine transport routes, particularly for Italy, which relies on this tunnel for transporting as much as one-third of its freight to northern Europe. It reduces the route from France to Turin by 50 kilometres (30 miles) and to Milan by 100 km (60 mi). Northeast of Mont Blanc's summit, the tunnel is about 15 km (10 mi) southwest of the tripoint with Switzerland, near Mont Dolent. The agreement between France and Italy on building a tunnel was signed in 1949. Two operating companies were founded, each responsible for one half of the tunnel: the French Autoroutes et tunnel du Mont-Blanc (ATMB), founded on 30 April 1958, and the Italian Società italiana per azioni per il Traforo del Monte Bianco (SITMB), founded on 1 September 1957. Drilling began in 1959 and was completed in 1962; the tunnel was opened to traffic on 19 July 1965. The tunnel is 11.611 km (7.215 mi) in length, 8.6 m (28 ft) in width, and 4.35 m (14.3 ft) in height. The passageway is not horizontal, but in a slightly inverted "V", which assists ventilation. The tunnel consists of a single gallery with a two-lane dual direction road. At the time of its construction, it was three times longer than any existing highway tunnel.The tunnel passes almost exactly under the summit of the Aiguille du Midi. At this spot, it lies 2,480 metres (8,140 ft) beneath the surface, making it the world's second deepest operational tunnel after the Gotthard Base Tunnel. The Mont Blanc Tunnel was originally managed by the two building companies. Following a fire in 1999 in which 39 people died, which showed how lack of coordination could hamper the safety of the tunnel, all the operations are managed by a single entity: MBT-EEIG, controlled by both ATMB and SITMB together, through a 50–50 shares distribution.An alternative route for road traffic between France to Italy is the Fréjus Road Tunnel. Road traffic grew steadily until 1994, even with the opening of the Fréjus tunnel. Since then, the combined traffic volume of the former has remained roughly constant.

The Géant Glacier (French: Glacier du Géant) is a large glacier on the French side of the Mont Blanc massif in the Alps. It is the main supplier of ice (via the Vallée Blanche) to the Mer de Glace which flows down towards Montenvers. It gets its name from the nearby Dent du Géant.

The Tour Ronde (3,792 metres (12,441 ft)) 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.

Mont Maudit (4,465 m) is a mountain in the Mont Blanc massif in France and Italy. The French name literally means "Cursed Mountain". Until the end of the 18th century, Mont Blanc and its satellite peaks were collectively known in French as the Montagne Maudite.

The Aiguille du Plan (3,673 m) is a mountain in the Mont Blanc massif in the French Alps. Its needle-like summit lies in the centre of the Chamonix Aiguilles when viewed from Chamonix.

The Aiguilles d'Entrèves (3,600 metres (11,800 ft)) is a mountain peak in the Mont Blanc massif of the Alps. It is situated at the head of the Glacier du Géant, and its rocky summit ridge forms part of the frontier between France and Italy. It lies east of the Tour Ronde, between the Col d'Entrèves and the Col Occidental de Toule. It has a steep, sound face of red granite and can be readily accessed from the Torino Hut/Pointe Helbronner.

Air India Flight 101 was a scheduled Air India passenger flight from Bombay to London, via Delhi, Beirut, and Geneva. On the morning of 24 January 1966 at 8:02 CET, on approach to Geneva, the Boeing 707 operating the flight accidentally flew into Mont Blanc in France, killing all 117 people on board. Among the victims was Dr. Homi Jehangir Bhabha, the founder and chairman of the Atomic Energy Commission of India.The crash occurred just a few hundred feet away from where an Air India Lockheed 749 Constellation operating Air India Flight 245 on a charter flight, had crashed in 1950.
