An open secret for a long time, officially and as a video can be marveled at today: Shawn Raboutou's first ascent of Boulder Alphane (9A). The strong American not only opened the first 9A boulder in Switzerland with the extremely strong and equally technical line, but only the third worldwide.

We have compiled a list of the most difficult boulders in the world from difficulty level 8C+. There are currently five 9A boulders: Alphane, Megatron, Return of the Sleepwalker, Burden of Dreams and Soudain Seul, with Alphane and Burden of Dreams being the only ones that have been repeated and graded.
