The nearest bigger town is Freising, perched on the Domberg above the Isar, with a cathedral and a brewery at Weihenstephan that claims to be the oldest in the world, running since 1040. That claim is proudly defended, and the brewery's tavern is a pleasant stop for a Bavarian lunch.
The plain is called the Münchner Schotterebene, and it was created by meltwater rivers pouring gravel out of the Alps. Under the surface lies a huge aquifer that feeds the city's drinking water. Peat bogs, the Moos, once covered the hollows, and were drained in the nineteenth century to create farmland, so the fields here are black soil and the villages have names ending in moos. The Echinger Lohe, a patch of rare heath near Eching, preserves a bit of the original landscape. The Isar and its side channels run quietly through woods and meadows.
The Walchensee and Kochelsee, named in this stop's label, lie far to the south in the Alps, and this is the other end of a long loop. Back on the plain, the roads are straight and fast, with the main risk coming from boredom and tractors. Surfaces are good, and traffic is dense around the airport and the autobahn junctions. Crosswinds can be strong in the open, and in autumn fog lies heavy on the fields in the morning. For a quieter route, follow the small roads along the Isar through Freising and Moosburg, where the river is lined with trees.
Practically, fuel stations are near every junction, with supermarkets and bakeries in all the towns. The airport area has hotels and restaurants. Freising has a lively old town, with cafes and breweries, and the cathedral hill makes a pleasant walk. Beer gardens are the best places to eat, with roast chicken, pretzels and cold beer, and some serve in a self-service style where you can bring your own picnic. Parking for motorcycles is plentiful, and the S-Bahn from the airport runs to central Munich.
