A trip to the Wachau region will let you ride through one of the most scenic parts of the Danube Bike Trail. This entire region is a UNESCO Heritage Site and for a good reason. There is the beautiful and historic monastery in Melk, the unforgettable scenery as you ride through the vineyards along the Danube and then, quaint Dürnstein with the castle ruins where King Richard the Lionhearted was kept prisoner. It doesn’t get much better than this!
A day to remember.

This is what we suggest:
Take the train to Melk, visit the monastery, bike on the Danube Bike Trail through the Wachau eating lunch in one of the many places along the way, ending the day with a leisurely ride on the train from Krems back to Vienna.
Train times are subject to changes but as of this writing there was a direct train every hour from Vienna to Melk. Travel time 1:15. Total bike kilometers 40.

Want a real Austrian adventure? After a 45 minute train ride you are in Neusiedl am See. From here you ride through the reeds along the lake to the National Park / bird sanctuary. Depending on the time of the year, you can see many of the birds that travel to Europe from Africa. Then to Illmitz to catch the ferry across the lake to Mörbisch. Here you will see just how big it is. Disembarking, you continue to Rust, known for three things; a quaint, beautiful town square, storks nesting on the houses and good food and wine. Pick one of the enticing restaurants. You won't be sorry! After lunch you ride through the villages along the lake and through vineyards back to Neusiedl for a well earned, relaxing ride back to Vienna.
You might want to do it again the next day!

This is what we suggest:
Take the train to Neusiedl am See, bike through the National Park/bird sanctuary, take the ferry across the lake, eat lunch in picturesque Rust, bike back to Neusiedl, ending the day with a leisurely ride on the train back to Vienna.
