The two cave routes
The short boat lands in two caves. The long boat lands in Sửng Sốt and rows through Luồn.
Route 1 is 3–4 hours for Thiên Cung, Đầu Gỗ, and Ba Hang. Ba Hang is three small notch caves that open onto two salt lakes. You kayak or take a rowboat.
The same boat passes Hòn Chó Đá and Hòn Đỉnh Hương. You look from the deck. It does not stop there. Route 2 is 5–6 hours for Ti Tốp, Sửng Sốt, and Luồn together.
Sung Sot Cave On Bồ Hòn. The port calls it the widest yet found, 20 m above the sea. 
Thien Cung Cave On đảo Đầu Gỗ. About 3,000 m², 20 m above the sea. 
Dau Go Cave The same landing as Thiên Cung. The port calls it one of the earliest known caves. 
Luon Cave You row or kayak through the notch into a lake.
