I recently climbed La Meije.
La Meije (in the center of the picture below) is one of the highest peaks in the Ecrins region of the French Alps.
After a day's walking to get from La Grave to the mountain refuge (refuge du Promontoire) perched at the foot of La Meije.
La Meije consists of a main summit (Grand Pic) followed by a ridge of four 'teeth' (below)
or subsidiary summits and after several hours we were standing on top of the "Finger of God", the final pinnacle, with the next mountain refuge in view (Refuge de L'aigle) in the valley below. We stopped by for a drink, then walked down for 3 extra hours to La Grave. Very long day.
Here is the sketch of the route to the Grand Pic
A very nice interactive view of the route is available here
