Trebenna west hosts several good routes. The perhaps best two of the ones I´ve climbed are Raki on the rocks and Flame of fame. Two routes similar to each other in many ways. Both share the same start leading up to a middle anchor at the bottom of an overhang. From there it’s possible to climb either straight up to do Raki on the rocks, or turn slightly to the right as I’ve done in the picture below.
Regardless of which way you choose, you will be in for steep climbing on good holds, leading up to a crux just before, or at the lip of the overhang. Hard routes to take down for someone with bad endurance like myself.
