I went on this tour as a BikeTours.com staff member. It is a popular option for our members who have already experienced the Passau to Vienna tour. The tour follows EuroVelo 6 along bike paths, quiet roads, and a few sections of gravel and dirt roads. The route starts and ends in two of the great cities of Europe; Vienna and Budapest. But I'll tell you a little secret, the hidden gems of this tour are the picturesque towns and cities that you visit along the way! My favorite cities were Bratislava and Gyor. In Bratislava, it is a must to take the short hike or bike up to Bratislava Castle. A beautiful view of the city and of the Danube river await you at the top. The castle itself is astonishing and it is easy to spend 2 or 3 hours just walking around admiring the garden, the castle, and the views. The old town of Bratislava is another area worth exploring on foot. Make sure you visit St Martin's Cathedral and Michael's Gate. If Wes Anderson was looking for a European city to film his next movie, it would be Gyor. This pastel wonderland of a city is not well known but it may have been my favorite city of the entire tour. Be sure to set aside a few hours to walk around the historic old town where there are many shops, restaurants, and bars to pop into. The dollar greatly outweighs Hungary's currency, the forint, so don't be afraid to take a tour of all the little pubs and restaurants. The local food and beers are great and incredibly inexpensive. The cycling for most of the route is flat and leisurely with a few shorter stretches of more moderate, slightly uphill cycling. Be prepared for a few sections of gravel roads as well as single lane dirt roads which can get a little rough at times. The distances vary from day to day with the longest day being 42 miles and the shortest being 25 miles. On day 6 you cycle to Visegrad from Komárom. If you are interested in getting some extra cycling miles in at this point, my recommendation is to skip the boat ride and cycle the entire route. The cycling is uphill at certain points and it makes for a very long day, about 53 miles, but the last 10-12 miles of the route as you cycle into the town of Nagyarmos are absolutely gorgeous (my favorite section of the entire route)! I highly recommend getting a drink and exploring Nagyarmos before you take the ferry across the river to your final destination, Visegrad. Another recommendation is to add a few extra nights throughout the tour. If you love big cities then think about adding extra nights before and after the tour in Vienna and Budapest. If you are like me and you love smaller cities that are very walkable and have a lot of character, Bratislava and Gyor would be my recommendations for extra nights. It is important to point out that while this route follows the Danube river, most of the time you cycle through the river valley, out of sight of the river. There is a lot of farmland and quaint villages and towns in this part of Europe so for large stretches of the route, this will be your surroundings.
