Throw stones until they cover the  dangerous rocky formations. Once done, attaach yourself to the pillar and let yourself to while swimming in stones. Should you "drown", you can pull yourself towards the upper part of the pillar. Once at the end of the rope, if any, detach yourself and keep going on. You should have enough practice at it. Done.

Or you could just ask the mighty stick to do it, and that's it.
