The great classical routes of the Olan are difficult, and the poor quality of the rock makes the climbing quite dangerous. Routes on the north-west side, from the Font-Turbat refuge, include: north ridge (AD), Couzy-Desmaison (ED), Devies-Gervasutti (TD), and the Candau ridge (D). . On the south-west face is the 'Pilier Nounours' (Teddy Bear pillar, TD), a modern route that was well equipped with bolts by J-M. Cambon.
