I'd like to cycle from Prague to Vienna (and maybe even Budapest) this summer. The only info I can find about the Greenways trail is by a group offering tours. I'd rather do it independently and wondered whether anyone out there has done this and could offer some advice. e.g. is the route easy to find and on quiet roads; is there a good place to hire / buy cycles in Prague; is accommodation en route easily available; am I advised to take a tent; etc.
Thanks in anticipation.
