Adam Ondra’s Five Hardest Boulder Problems
With his recent repeat of Soudain Seul V17, Adam Ondra has once again proved that he's one of the world's best rock climbers

Adam Ondra is one of the world’s best rock climbers. He has more 5.15 sends than anyone, more hard flashes than most of the other top climbers, he made the second ascent of the Dawn Wall (5.14, 32 pitches), and has now repeated a problem graded V17 called Soudain Seul.
Below are five of Ondra’s hardest boulder problems to date, note that he’s climbed several other V15s over the years. Only Ondra and Jakob Schubert have climbed proposed 5.15d sport routes and boulders that were graded V17. Read more about Ondra’s V17 ascent here.
