How to photograph caves

Caves are lit artificially — show caves have fixed lighting, so a fast lens and high ISO beat flash, which flattens formations.

  • Many show caves restrict tripods on tours; ask in advance or bring a small beanbag.
  • Use manual focus with focus peaking in low light.
  • Never touch formations — skin oils stop their growth.
  • Follow White-nose Syndrome decontamination rules where posted to protect bats.

Season: Cave interiors stay at a constant temperature year-round; summer tours fill up, so book ahead.
