The World’s Hardest Boulder Problems by Country

Climbers have been climbing boulder problems for over 100 years. There are now dozens of V15s and a handful of V16 problems with at least two V17s.

Pierre Allain is considered one of the first boulderers and in the 1930s, he was joined by several others at Fontainebleau, where his group of “‘Bleausards” developed a love of of the sport that went beyond simple training for the Alps.

One of the most famous routes they climbed is L’Angle Allain V2, first done in 1934. Allain designed the first rubber-soled climbing shoe. Watch an ascent of L’Angle Allain below.
