The regional train from Boeblingen to Singen takes 2 hours. We bought the Baden-Württemberg-Ticket for 25 Euro plus 10 Euro for bike tickets. With this ticket we can take every regional train in BaWü. Our plan is to cycle from Singen to Konstanz today. The weather is quite nice – actually one of the first really nice days this year. We leave the train and cycle to Ueberlingen am Rhein. From there the road continues to Radolfzell at Lake Constance. After a longer break in the sun and having an apple juice with sparkling water we continue cycling into the direction of Konstanz until we see a sign which says Reichenau. Reichenau is a small island which has been nominated as World Heritage Site. So we decide this is a good chance to have a closer look here. We cycle to the island which is only connected to the mainland by one road with a huge alley. The island is quite nice – but still annoying that there are so many cars driving around. Instead of cycling all the way back we decide to take the ferry from Reichenau to Konstanz. It costs 18 Euro per person including bike – quite expensive... but still we think it's worth to do it. While waiting for the ferry we are sitting in the sun eating lots of ice cream from an ice cream parlour nearby. The ferry was quite small and there were not so many people on board. We enjoyed the one hour drive to Konstanz. In Konstanz there were many people around. The weather was still beautiful, but we had to take the next train home. But we are sure that we will come back to cycle another part along the lake and then maybe stay a bit longer than just one day.
