I am so excited to be taking my young teens to Europe for the first time! Our family of four will be renting bikes from Détours de Loire this summer and doing a 6 day, self-guided trip starting in Blois and dropping the bikes off in Tours. We would then have two nights giving us one full BONUS day of sightseeing before we return to Paris for 4 nights.
The current idea is to stay in Tours and explore Tours on Day 7 but maybe we should take advantage of the great train connections in Tours and Saint-Pierre-des-Corps? Maybe we could spend our 7th day somewhere really neat and still have an easy connection (3 or fewer hours) back to Paris?
Here are our interests: I enjoy architecture and gardens. (I am really looking forward to the Loire!) On previous visits, I loved smaller places like Bruges and found Paris a bit overwhelming. My husband simply wants to be active. The kids are young teens and they say they are interested in castles, stone age ruins, Roman empire ruins, the solar system and outer space, science museums, water parks and general active things. A cave or underground tunnel could be neat and we don't currently have plans to see any in the Blois to Tours part of our trip. We are pretty casual when it come to food and the oldest teen is a vegetarian as much as possible.
Our bonus day would need to be easy to do. We won't have a car but we can do trains, a taxi, public transport, bike rental and a lot of walking. We are open to all of your ideas. Based on my research, we are interested in your opinions on Saumur to try to see the Grand Dolmen (although the reviews on TripAdvisor say that it may not be open), Angers to see the Chateau with it's stone age finds in the basement/foundation, Nantes to see Les Machines de L'île and walk around the Chateau and Cathedral. (If this trip goes well I am hoping to put together some future multi-day trip to the Gulf of Morbihan and Carnac).
