Travel bucket list idea:
The mysterious but fascinating troglodyte world of the Loire is the fascinating underside of all those lovely white stone chateaux.
Thousands of kilometres of tunnels – originally dug out of the soft, underlying, tufa strata as part of Middle Age stone quarries – became chapels, houses and farms to create the largest troglodyte region in Europe. Some are still lived in, while others have been converted into hotels and restaurants, dramatic wine cellars (providing ideal conditions for storing wine), mushroom farms and even a zoo.

Most of the sites are located in and around the towns of Saumur and Doue-la-Fontaine or around Azay-le-Rideau. No booking is required – you can just show up – but if you want a guided tour in English, sometimes you need to email ahead.
The temperature in the caves remains a constant 12C all year round – pleasantly refreshing on hot summer days – but you’ll need a sweater.
Most sites close in January and February and sometimes November and February, so check timings before you plan or go.
