Aiguille d'Entrèves is a granite spire of the Mont Blanc Massif along the main watershed and hence on the border between Italy and France. Easy access from Punta Helbronner--reachable via cable car--fun climbing routes, and great views make it a popular destination.
The most complete source of information for this peak is Monte Bianco, Volume I by G. Buscaini, while the Vallot guide skips this minor summit. Buscaini tells us that the name of the peak derives from the one the village below on the Courmayeur side. Entrèves means "between the streams."
There are half a dozen well-established routes to the summit, the most popular of which is the south-to-north traverse described in this route page. The traverse links the southwest ridge route to the normal route from the northeast; the latter is used for the descent. The west face offers more challenging itineraries.
There is a little discrepancy between the Italian and the French maps regarding the elevation of the summit. The former gives 3604 m versus the 3600 m of the latter.
The easiest access to Aiguille d'Entrèves is from Punta Helbronner, which is usually reached by cable car from la Palud near Entrèves. Purists can take a steep trail that follows more or less the course of the cable car. When returning to the Italian side, it is better to skip Punta Helbronner and descend to Rifugio Torino, to board the cable car at the second intermediate station.
If coming from Chamonix, one can reach Refuge des Cosmiques at Col du Midi. From there it is possible to cross Vallée Blanche and Glacier du Géant, or, if it is running, continue with the cable car from Aiguille du Midi to Punta Helbronner.

No permits are required and no fees must be paid to climb Aiguille d'Entrèves. Since it is on the Italian-French border, carry some means of identification.
When To Climb
The period from mid June to mid September usually offers the best conditions. Access on skis should be possible year-round--weather permitting. The rock climbs would be substantially more challenging off season.
Once again, a list of possible camping sites can be found on the main Mont Blanc GROUP page. The most convenient moutain hut for Aiguille d'Entrèves is Rifugio Torino. It is quite possible, though, to climb this summit without spending the night at the hut.
