Inside and outside

15 °C inside, all year.

Deep inside, a cave keeps the average temperature of the year outside: about 15 °C here, in January and in August. In August the afternoon reaches 24 °C at the entrance, 8 °C warmer than inside: take a jacket. The wettest months are from November to January: water rises fast underground, so never go in without a guide after heavy rain.
