Biranha is a beautiful route and is rated as 6a+. It took us a while to find the start of this route. We were glad, that we found it. It's an airy climb. The lower part has quite a bit of loose rocks. The last two pitches are fabulous, if you like more athletic climbs as we do. I tried to mark the route.
