Tham Phay Cave Expedition - 1 Day

This 1 day adventure journey explores Ba Be National Park, around 230 km north of Hanoi in Bac Kan province. The route weaves together Ba Be National Park, Tham Phay Cave and Underground river at a calm, well-paced rhythm, set against one of the world's 20 largest natural freshwater lakes, ringed by limestone karst, flooded forest, river caves and Tay, Dao and H'mong villages.

You travel with a small group with an English-speaking guide, so the timing stays flexible. Pickup, pace and stops are shaped around your group rather than a rigid coach timetable, and the route favours genuine local encounters over the busiest tourist sites.
