Roll out of Deggendorf on a 75.3 km loop that stays paved almost the whole way. Soon you're at the Isarmündung nature reserve, then past Schloß Niederpöring and Schloss Loham, castle after castle. The Vogelfreistätte Graureiherkolonie nature reserve and the Brutbiotop follow before the Deggendorfer Himmelreich, and then it's back to where you started.
