Sung Sot Grotto
Việt Hải, Cát Hải, Quảng Ninh
Sung Sot GrottoSung Sot or "Surprise" Grotto is a system of huge, open caves, some large enough to fit a theater full of people. The grotto is on Bo Hon island and is reached by 50 steep steps from the wharf and then another 10 down into the grotto. After that, the grotto itself is a piece of cake as it's lit and has smooth walking surfaces. Monkeys and vegetation have made their way in, adding to the unique atmosphere, especially at the area called the "Royal Garden."
