Some great day trips include:
- a trip to Wiesbaden (25 minutes via subway), the posh spa/casino town or Mainz (20 minutes via subway) with a lovely old town and the world-famous Gutenberg Museum
- a trip to the picturesque town of Idstein (25 minutes via train or car from downtown Frankfurt or the airport). The town's high school is located in the 400 year old castle. No castle ruins here, just the real deal. Also the beautifully restored "little castle" is now a 4 star hotel (Hoerhof hotel/restaurant) featuring fine dining. Big savings can be had lodging in this centrally located town versus staying in the larger towns without loosing the convenience or accessibility to the other locations listed here as day trips. If you are visiting in Spring, don't miss the Jazz festival. Three days of music from more than 30 bands. Music for anyones taste can be found.
