The Son Doong Cave has a total length of nearly 9 km long and the volume is up to 38.5 million cubic metres, which makes this cave the largest natural cave on the planet. With this volume, Hang Son Doong is 5 times larger than Deer cave in Malaysia, which was said to be the largest natural cave ( before Hang Son Doong was discovered) with 9.5 million cubic metres of volume. However, what makes Son Doong special, recognized and well-known by the world is the unique hidden underground world inside the cave itself. It has many complex and giant stalactites (over 80m high), primaeval rain forests growing inside the cave, its own ecosystem, weather or a mysterious underground river that no explorer has yet discovered to the end of it. Many visitors admitted that the Hang Son Doong Cave is like another world, Ginger Zee from ABC News's - Good Morning America exclaimed that the sceneries in Son Doong were like those in the Avatar movie.
This amazing cave also houses an impressive ecosystem, inside the largest cave passage in the world.

The Marble Mountains are one of central Vietnam’s most stunning and unique sights to see. The five mountains – made from marble as their name suggests – rise dramatically out of a flat plain just outside of Da Nang, looking almost impossibly out of place. The five natural Marble Mountains are each named for one of the five natural elements of Chinese feng shui: Fire, Plant, Soil, Water, and Metal, and are an important sacred site to Vietnamese Buddhists.
Blessed by nature, the Marble Mountains are wonderful to visit at any time of the year. The most beautiful season to experience these tropical coastal mountains, though, is summer (June – August). But be aware that you must climb many stairs, so breathable clothing and water is a must. You may want to avoid the stormy season (usually from September – November end) as the weather is more unpredictable and the stairs become dangerous when wet. You should make a day of visiting the Marble Mountains and then continue to Hoi An, to enjoy the beautiful beaches and fresh seafood for lunch. Wake up early and head to the Marble Mountains when there are few visitors and the air is still cool.
