Show caves versus wild caves
Show caves have paths, lighting and guides, so you do not need equipment or experience. Wild caves are for experienced cavers with training and gear. This list covers show caves and well-organised guided tours.
Caves worth an afternoon
- Postojna Cave, Slovenia: A train takes you through huge chambers, and the nearby Predjama Castle is built into a cliff. Allow 3 to 4 hours.
- Waitomo Caves, New Zealand: Boat rides under glowworms. Book in advance, and choose between gentle boat tours and more active black-water rafting.
- Škocjan Caves, Slovenia: A UNESCO site with a vast underground canyon.
- Mammoth Cave, USA: The world's longest known cave system has several guided tours. Pick a short tour for an afternoon.
- Gruta de las Maravillas, Spain: In Aracena, with colourful formations and a short tour.
- Cheddar Gorge and Caves, UK: Easy to reach and suitable for families.
- Phong Nha–Kẻ Bàng, Vietnam: Paradise Cave has a boardwalk and is accessible to most visitors.
What to wear and bring
Caves are typically 8 to 14 °C all year, so bring a light jacket. Wear shoes with grip, since paths can be wet. Take a small bag and leave bulky luggage in the car.
Safety and etiquette
- Follow your guide and stay on marked paths.
- Do not touch formations: oils from your skin damage them.
- Check whether flash photography is allowed.
- If you have mobility problems or claustrophobia, ask about the route before booking.
- Check weather: some caves close after heavy rain.
Opening hours and tour options change, so book ahead and check conditions.
