Tips for Visiting Phong Nha Cave Responsibly
As a UNESCO World Heritage site within a protected national park, Phong Nha Cave deserves respectful and responsible tourism. Keep these tips in mind:

✅ Keep noise low. Caves amplify sound, so speak softly to preserve the peaceful atmosphere.
✅ Wear sturdy footwear for slippery paths inside the cave. Avoid flip-flops.

✅ Support local businesses by hiring local guides, eating at nearby restaurants, and staying in locally owned accommodations.
