Hello!
I did a cycling tour of the Loire from Nantes to Orléans in August 2008 with my cousin (we're both 24 years old) and we loved it. And so we've been inspired to do more, wither to the source of the Loire, or perhaps further - and do the Eurovélo 6.
We don't know when we'll do this project yet (depends on work, holidays, etc.), but we really want to. (And we have nothing against teaming up with other adventurers!)
I just wanted to hear about other peoples' experiences. I also wanted to know what you did, after you arrived in Constanta. How did you get back? Did you take the train? Fly? Turn your bikes around and go back the way you came?
Thanks for your answers!

Generally speaking, the route profile:
source of the Danube - Black Sea is a descent, and therefore a little bit easier.
There are no cycle paths in Romania, so you need to take care, even though traffic is light. (watch out for dangerous drivers and unreliable cars!)
I didn't go to Constanta, personally. I opted for Tulcea to get to Sulina. It's less touristy and more authentic.
If you don't want it to be a hard slog, you really need to get the "Donauradweg" guides (available in English or German) which set out the entire route.
About the return - the Black Sea - Bucharest route is fairly straightforward. They'll tell you that bikes are not permitted when you buy your tickets in stations, but ignore that. In the train, however, you are under the dictatorship of the controller. You'll need to firmly discuss the amount of the baksheesh!
With Bucharest - Vienna, on the other hand, it's the same thing but you'll need to point out that you have bikes with you.
To cross Austria, you'll need one ticket for yourself and another for your bike. The same goes for reservations.
Swiss and Austrian trains do have bike compartments, but they can't hold many bikes so you will have to reserve your space!

We are planning to do the route in 2012 finishing in June around the 23rd June. You can fly back from Constanta with Ryanir but the train might be the best way...as per the Eurovelo policy. Valerie Penny

I would prefer train but where do I start to book and are bikes welcome?
thanks for your reply
