Prague to Salzburg to Vienna

I think the best you can do is research what you are going to be doing in each place and divide the days up according to that. I am going to Prague for 4 days and Vienna for 2. In Rick's travel books he says what he thinks is the minimum amount of days for each city. I would suggest picking up some sort of guide book, again to get an idea of what you want to see in each place.

Hi Sandi,
... we haven't done it because we didn't know about bike tours, but now we know that an intersted person can rent a bike and ride it on wide, paved, level bike trail alongside the Danube... You can likely find details by typing in "bicycle rental, Danube, Vienna" at Google.com.
... Gute Reise! P

I will try and not be biased as I do live in Salzburg (love the city)... but, I would recommend at least spending one full day here. One day gives you enough time to see the basics of the city. If you stay two, I would recommend either scaling the Untersberg or the Fortress! In Vienna you can see everything in one day, but two to really see all the sites (There are so many museums!). I'm going to Prague for the first time this coming weekend and am spending 2.5 days there; however, I have heard you can see everything in one day and it's pretty pricy. Salzburg is also pretty expensive, especially compared to Vienna. The Eagles nest is just 30 min from here and highly recommended. Hallstatt is a day trip. Hope this helps... if you need any information and details, let me know!

Time to start getting organized - plan your trip so you don't have to backtrack.
Prague is worth at least two full days (read up on RS literature). The Czech Republic thrives on bike touring and you should have no trouble renting them. Czech roads are so well-maintained (once out in the country) that it's a delight to bike.
Decide if you want to head toward Salzburg or Vienna - different directions. If Salzburg: Next stop is Tabor (medieval center), then follow the castles (esp. Hluboka outside Budweis/Budejovice) south to Budweis & Cesky Krumlov/Krumau. Exceptionally preserved medieval towns! Take bike or boat ride along the Vltava/Moldau. Then south to Freistadt in Austria (another medieval center). Then Linz (see Roman castell and downtown) and from there to Salzburg.
Going to Vienna: Kutna Hora and its cathedral, Jihlava (walled city) Telc (incredible town center), Brno (cap. of Moravia) and then Vienna. Lots of gentle countryside to ride in! 3 days minimum in Vienna.

Vienna now has bikes to rent all over town. You put your credit card in a box and it gives instructions in English on how to unlock one. It's about 1 Euro per hour. You just return it to another station in town.

Also in Vienna, check out Vienna Walks and Talks - http://www.viennawalks.tix.at/pages/engl/portal5.php. I've heard their bike tour is good.
Salzburg can be seen in 2 days as well as Prague. Vienna can take several days if you want to do all the museums and sites. Plus, the gardens are beautiful and you have to go to the opera. You can go to Mauthausen concentration camp and Melk Abbey. Both good stops. Good luck.

I would personally say 4 days minimum for Prague. Vienna could be done in a day. I was there for 2.5 days and was bored - perhaps I'm in the minority there. Don't get me wrong, it was a beautiful city. But there wasn't a whole lot to do that interested me.

Vienna in one day? Must be joking - while Prague often has been compared to a Vienna of a bygone era, it is much more accessible to visitors and has the wealth of history and culture Prague can't share.

Rick Steves often hits the highlights, but I must correct him one one great error - Krems and the Wachau is nowhere near Mauthausen (unless you measure distance American-style). The concentration camp memorial is close to Linz and across the river from Enns in Upper Austria.

The Danube Bike Trail is well-marked and easily navigated (since it's mostly level). You can rent bikes at railroad stations all over Austria, and my friends have taken the Vienna -Brno - Prague route several times and rave about it.
