Each participant will be provided with drinking water, a helmet, and all necessary gear before setting off on a 3 km trek through the lush Sinh Ton Valley. The trail winds through pristine rainforest, crosses crystal-clear streams, and passes beneath towering limestone cliffs.
10:30 Reach Hang Vang, a hidden cave nestled deep in the jungle. Despite its modest size, the cave is renowned for its impressive chambers filled with massive, sparkling stalactites and stalagmites. Take time to explore the cave, capture photos, and learn about its fascinating geological history before enjoying a light snack and a short break at the entrance.

The cave extends for approximately 4 km, and the expedition explores around 1.5–2 km inside before returning. The only sounds are the gentle strokes of your paddle and the echo of water in this extraordinary hidden world, while your guide ensures a safe and enjoyable experience throughout.
16:00 Return to the cave entrance and enjoy free time to swim in the crystal-clear water, relax on floating tubes, or simply unwind beside the emerald pool.
