Butzbach - in the heart of the Wetterau...

Some little ideas close by - perhaps even for a bicycle tour:
- The castle at Münzenberg
- the monastery ruins at Arnsburg
- and it's the perfect season for the Rose Museum at Steinfurth.

Have you been to Marburg yet? Walk around, explore the historical centre, climb up to the castle. You'll love it.
Best restaurant in town: "Sonne" in the market square. (Hope it's still as good as it used to be!)

The ruins of Burg Greifenstein, above the Dill valley, North of Wetzlar.

Limburg with its cathedral.

Weilburg, by the way, offers more than the tunnel. It's a small baroque residence, designed shortly after 1700, with palace, garden, town - and an imposing church (which is "my darling" because I did a lot of historical research about it. It was me who wrote the little guide-book they're selling. Unfortunately it's in German only.)
