Dicoveed in 1958 by sheer accident, while digging out stones in the local stone quarry, these caves are considered the most beautiful in Belgium.

A breath-taking visit

Get ready to...

  • go 65 metres underground
  • explore a fantastic maze of galleries
  • look over a 30 metres deep sinkhole
  • be wowed by delicate curtains made of stone, the incredible shapes and colours of the concretions around
  • listen to the "river with no name" (an underground stream with incredibly clear water) roar
  • glimpse a bat or two...

By the caves


  • walks with stunning panoramas
  • gardens with panels presenting the Calestiennes's flora and fauna
  • the play area

Birthday parties

  • Caving trail (from the age of 6)
  • Fun storytelling
  • Cake and gifts for all

We loved

  • The excentric concretions
  • The 35 metres high room where we felts as small as ants
  • The baby stalactites as cute as Christmas decorations
  • The fact that the caves are 12 degrees all year round (which feels great in winter!).
