When coming to Phong Nha, don't miss out the experience of the 7 km Paradise Cave adventure in Phong Nha, that will be a stunning mix of natural wonder and physical challenge. 

I. What to Expect:

• Start in the lit first kilometre on boardwalks and staircases, viewing huge chambers filled with sparkling stalactites and stalagmites
• Beyond the tourist path, you venture deeper in near-darkness using flashlights (a guide supplies headlamps and sandals)
• Dynamic terrain involves crawling through narrow passages, trekking over slippery rocks, and sometimes chest-deep river wading or kayaking — with boats for non-swimmers .
• Reach the “Heaven Well”, a magical skylight chamber where sunlight shines down onto an underground stream—often the highlight.
• Lunch underground, riverside, often at this breathtaking spot
• Return trip follows the same route back, exiting the cave around mid‑afternoon

II. Physical & Safety Factors:

• Moderate to strenuous: requires climbing, scrambling, river wading, kayak pushing.
• Fitness recommended: outing includes uneven terrain, narrow tunnels, and humid conditions
• Gear included: headlamps, helmets, sandals/shoes, guide support, and safety briefings

III. Tips for a Great 7 km Tour

• Bring moisture-wicking, quick-dry clothes, waterproof or trekking shoes with good grip, swimwear, towel.
• Pack a waterproof bag, and consider a waterproof phone case if you want photos .
• Check season/weather: during rainy months water can rise and tours might only go 4 km
• Show respect for the cave: avoid touching formations; they take thousands of years to form
