Languedoc is highly seasonal, but over the last few years weather
has become less predictable. You should therefore bring a range
of clothing, including waterproofs. You should also allow for
extremely hot weather in the summer (light clothing, sun hats,
sun cream, etc).
Some Cathar Castles are located on mountain tops. Climbs are
not too demanding - 10-40 mins.
Safety precautions in France are not the same as those in most
English speaking countries, so sturdy footware and hiking sticks
are recommended as a few of the paths are very uneven.
Holiday Insurance is recommended, as is a mobile telephone (cellphone).
Other things you might find useful: camera, torch, binoculars,
map of the languedoc, compass, books on the Cathars or Cathar
