Getting there
Lung Khuy sits in the hills above Quan Ba, around 45 minutes from the Heaven Gate. A paved road leads to the village, followed by a gentle walk of about 20 minutes through farmland.
Inside the cave
The cave stretches several hundred metres with lit walkways, stalactites and wide chambers. It stays cool all year — a welcome break on a hot riding day.
Tips for your visit
Wear shoes with grip, bring a little cash for the entrance ticket and go early in the day to have the chambers almost to yourself. It is included on our four-day loop.
