Pete, you might also check out the King Ludwig Way from Starnberg to Schwangau, near Fuessen, especially if you're interested in Bavarian history and the sad tale of so-called "Mad" King Ludwig II of Bavaria. [Not "mad" at all imho - just gay and the State couldn't handle that! OK, he was profligate too, but in the bigger picture the tourist revenues which Bavaria has accrued over the past 130 years from visitors to his castles greatly exceed the debts he incurred while building them].

I've not ridden this trail but will one day. There are minor variations between the cycle route and the walkers' route, but I expect both will be well signposted. I have two English-language guidebooks about the route - probably out of print but you may get lucky via Amazon Marketplace. If I were you I wouldn't feel too bad about taking the train to Starnberg and starting my tour there, if time is short. It's an easy run on the S-Bahn from Munich. And probably the town in Europe I'd most like to live in, given its proximity to a great cultural city, the Alps and Italy just a couple of hours away...
