FAQ

Do I need to know how to swim to join the tour?

Swimming is part of the Dark Cave experience, but life jackets are provided. If you’re not comfortable swimming, let your guide know — they can assist or adjust the activity as needed.

Can I skip the zipline or mud bath?

Yes, both activities are optional. If you’d rather not participate, you can enjoy the surrounding area or wait for the group nearby.

Is the Dark Cave suitable for children?

The activities at Dark Cave involve ziplining, swimming, and walking through slippery areas in low light. It’s better suited for older children (10+) who are confident in the water and okay with a bit of adventure.

How wet or muddy will I get in Dark Cave?

Very! Expect to walk and slide through a natural mud pool inside the cave, followed by a swim in the river. Bring swimwear and a towel — you’ll need both.

What happens if it rains during the tour?

Light rain won’t stop the tour, but heavy rain or flash flood warnings may delay or cancel some activities, especially those in Dark Cave. We’ll always prioritize your safety and keep you updated.

Can I do this tour if I have a fear of tight spaces?

Dark Cave involves narrow paths and low light, which may be uncomfortable for those with claustrophobia. Phong Nha Cave, however, is spacious and scenic — let us know your concern so we can advise the best option.

Can I combine this tour with an overnight stay in Phong Nha?

Absolutely. You can start or end the tour in either Dong Hoi or Phong Nha. Let us know your travel plans and we’ll help with transfers or overnight bookings.
