Anyone with information is asked to call 101 quoting log 306 19/01/17.
Robert Campbell, Mountain Bike Manager for Natural Resources Wales (NRW), told Wales Online: "Sabotaging woodlands is incredibly dangerous and puts people at risk. If anyone sees evidence of dangerous behaviour or activity please contact the police to report it."
Caerphilly mountain lies between Cardiff and Caerphilly at the southern edge of the South Wales Coalfield, and its summit is 271 metres (889 ft) above sea level.
