We just completed a visit to Chenonceau, using information in the 2013 Rick Steves France Guide and found that some of the information appeared to be out of date. We took the city bus from Amboise. The book said it would cost €1,20 each way (leaving from the Theatre bus stop). However, the cost was €2 each way. The book also said to get off at the second stop in Chenonceaux, rather than the stop in front of the TI. However, the stop for visiting the castle was in front of the TI, leaving just a short walk to the main entrance. I'm not sure if there's another stop in town now, but the driver (and the interior route sign at the front of the bus) both indicated that people visiting the chateau had to get out at the first stop. Other than those small glitches, the bus was a great way to get to the chateau in air-conditioned comfort (during a spell of 90-degree weather) and for a minimal cost. There's an illustrated, electronic sign board at the front of the bus, so there's no confusion about where you are on the route or what stop will be next. You pay as you board the bus. We bought our chateau tickets at the TI, which also was open at least 10 minutes earlier than the 9:30 a.m. opening time listed in the guide book.
Another great way to get to Chenonceax from Amboise is by bicycle. I did this round trip route in Sept 2012 and it was perfect. I was not a bike rider and hadn't been on a bike for years before this outing and there were some daunting hills at the beginning and end, but the ride in between was beautiful. You are on a path for most of the trip and go through the countryside and some small villages. I spent two weeks in France that trip and this ride was one of my favorite things. You can rent bikes for a reasonable price in town. There is a tourism office that can give you a map and directions, but the easiest thing is to follow the signs along the path. Happy riding!
Brooke, thank you for that info!! I would love to ride from Amboise and back by bike. Now I have to go back just to do that... ;).. I LOVE Chenonceau, my all time favorite chateau in the Loire. Sue, thanks for your report, hope you enjoyed your time there.
