We'll meet at col des Aravis at 1486m, leaving here souvenirs shops and bar's terasses (for a while...) to start an easy path through alpine pastures wich gets steeper for 1h30 of sustained effort on a not very marked track and scree. Walking sticks will be helpfull.
Finally we'll discover this nice hidden arête, starting its climb at about 2050m high. Let's go for 300m of pleasure !
3 nice slabby pitches of grade 4 on a compact and solid limestone leads us onto the arête that we're going to ride for quite a while, by an easy juggy climb (grade 2 to 4a), but sometimes exposed and airy, giving us time to admire the high snowy summits of the Mont-Blanc range. Climbing shoes will be usefull, at least for the first part of the climb.
After 3-4h of climb we'll reach the obvious summit, where we'll make break and have lunch.
We'll get down by walking and a bit of easy downclimb to the gully and its steep scree slopes where skills of good hiker are needed. The descent takes 1h30 to join the col des Aravis where we could have a dring at the terrasse of the bar !
Difficulty : AD- couple grade 4 pitches, approach and descent on steep track and scree slopes, for good level hikers
Height difference : 900m of whom 300m rock climbing
Timing : 1h30 approach, 3-4h climb, 1h30 descent so about 7h without the breaks
