Roll out of Otterfing and past Schloss Harmating, a castle, before the route slips into the Isarauen nature reserve between Schäftlarn and Bad Tölz. Next come Forstenrieder Park and Burg Grünwald, another castle, then the Deisenhofener Forst and the Hofoldinger und Höhenkirchner Forst, both nature reserves. Of the 79.8 km, 96% is paved and 4% unpaved, with 621 m of climbing along the way. Then it's back to Otterfing to close the loop.
