The route starts at the Weichtalhaus in Höllental. You can park your car for free there and might wanna use it as a personal aid station after the first long descend. The first mountain top of the route is Klosterwappen on top of Schneeberg. Therefore you start going up Weichtalklamm on the right hand side of the hut. It is a narrow canyon at some sections with chains and ladders as support. no need for any special gear, just hold on to whatever is provided. The ascend passes Kientalerhütte later on and finishes with a long uphill on top of Schneeberg. From there, turn around and follow the same way back down until where you entered the Klamm when going up. There you follow the forrest road for a little while and then drop left down into the forrest and back to Weichtalhaus. I recommend fillip up your water there or from your car before going on. Cross the bridge and follow the road to the right until right before the tunnel starts. There is a narrow path going up the mountain on the laft. Follow the trail up Wachthüttelkamm from there. It is quite steep, again equipped with a lot of chains and ladders. Higher up it becomes flatter and leads you to Otto Schutz Haus (might wanna fill up water again there). There you cross the balcony and follow the trail always along the cliff towards neue Seehütte. Before reaching it however, the trail takes you to the right up a little hill to the higher plateau. Up there turn right again and cross it. At the next junction follow the sign to Gloggnitzer Hütte and from there down Kesselgraben. You will finish at the road after the long downhill, turn right and follow the road (carefull with the traffic) back to the Weichtalhaus. Cross the bridge again and finish your attempt when reaching the balcony of the hut.
There is generally not too much running water on the route, so i recommend putting enough in your car and using the huts to refill.
