1.4 Map of the Area

The area where the summit is located is in the Chamonix valley (Upper Savoy, France) in the area called Aiguilles Rouges, north of Chamonix. The route and approach to the route are completed in one day.
From the campsite, it is necessary to reach the Flegere cable car, the second section of which goes to the Index summit. To ascend:
- Move along the cable car or along the ski slope passing nearby.
- From the upper cable car station, move along the trail to the left for 5 minutes.
Distance to the start of the route — about 5 km. Travel time is 3 hours.
You can also use the cable car (starts at 08:00, it is better to buy tickets in advance). In this case, the ascent time will be 20 minutes.
2. Characteristics of the Route

| Section № | Terrain Characteristics | Category of Difficulty | Length |
|---|---|---|---|
| R0–R1 | Rocks | 5Б | 45 m |
| R1–R2 | Rocks | 4С | 35 m |
| R2–R3 | Rocks | - | 45 m |
| R3–R4 | Rocks | 5Б | 30 m |
| R4–R5 | Rocks | 5С | 30 m |
| R5–R6 | Rocks | 5Б | 20 m |
| R6–R7 | Rocks | 5Б | 25 m |
| R7–R8 | Rocks | 3С | 20 m |
| Descent from the route | Rocks | 250 m |
3. Characteristics of Team Actions
| Section № | Description | Photo № |
|---|---|---|
| R0–R1 | Cat. diff. of climbing 5Б. Need to overcome a 45 m slab, with the key section being a steep part approximately in the middle. | 1,2 |
| R1–R2 | Movement along the ridge 35 m to a drilled station under a ledge, cat. diff. 4С. | |
| R2–R3 | Exit to a wide ledge, 45 m. Simultaneous movement is possible. On the ledge — to the right, to the start of the third rope. From this ledge, an emergency descent from the route is possible by climbing simple rocks. | 3 |
| R3–R4 | Movement up the slab slightly to the right, and then back to the left. The first bolt is at a height of about 15 m; it is recommended to organize additional belays. 30 m, cat. diff. 5Б. | |
| R4–R5 | Continue moving along the slab along the crack. This section is key: cat. diff. 5С, 30 m. | |
| R5–R6 | Movement up the slabs 20 m, cat. diff. 5Б. The station is clearly visible. If there are many people on the route and the participants' qualifications allow them to move on more complex terrain, then by moving not strictly up, but up and to the left, overcoming a section of 5th cat. diff., cat. diff. 6А, 20 m, you can get to a grassy ledge, from which it is quite easy (3rd cat. diff. instead of 4th cat. diff. of section R6–R7) to reach point R7. | |
| R6–R7 | Movement up a steep wall divided by a crack. Ignore the ascent leading to the right. 25 m, cat. diff. 5Б. From point R6, you can go to the right: at first, this option seems simpler (4th cat. diff., cat. diff. 5), but in this case, to reach the summit, you will have to overcome a section (5th cat. diff., cat. diff. 6) about 20 m. | |
| R7–R8 | Climbing cat. diff. 3С to exit to the ridge 15 m. Then traverse to the summit 5 m. The summit is a narrow ridge. On this section, it is convenient to use loops for belays on large ledges. | 4 |
| Descent from the route | Traverse along the ridge 10 m to the right, descent 5 m to a ledge and traverse 10 m to rappelling stations. Two rappelling options are possible. The optimal one is towards Col de L'Index on the ridge — 45 m. The main difficulty is to get to a point in one rope from which you can continue moving by simple climbing (see photo 5, which shows the most successful descent point). After that, climb down simple rocks to the pass and continue moving along the scree slope to the cable car. If this rappel is occupied, a descent to the northwest is possible. The descent is carried out in two ropes — 25 m, an intermediate station is drilled. Then you need to climb to Col de L'Index and continue moving along the scree slope to the cable car. | 4–6 |
Along with the route along the South-East ridge, it is one of the most popular routes to the Index summit. All stations, including the rappelling one, are drilled.
There are also bolted hooks every 10–15 meters on the route, but it is recommended to take a set of medium-sized stoppers for additional belays.
The bolted hooks make it quite easy to navigate the route.
Due to the popularity of the route, it is recommended to start before 08:00, as most people take the cable car. If taking the cable car, it is recommended to buy tickets in advance to be able to ascend on the first cabin.
The path to the route is clearly visible. The route is not rockfall-prone.
The proposed assessment of the route is 3A.
