Visiting Vietnam? Do check out these lesser-known hidden gems

Despite being a UNESCO World Heritage Site, the Phong Nha-Ke Bang is one of the least known gems of Vietnam.

For starters, the national park contains an amazing limestone cave complex.

The place also has the largest natural cave in the world, which was discovered in 2009.

So take a boat ride, and marvel at its natural landscape, and rich flora and fauna.

It might sound unfair to call the country's tallest peak as a 'hidden gem', but the Fansipan Mountain remains largely unexplored by international tourists coming to Vietnam.

The mountain top offers some spectacular views of northern Vietnam, and even some glimpses of the Yulong Mountain in China.

The place is a favorite among hikers. So, if you're up for it, head to the Fansipan.

Seeking a quaint and natural escape? Head to Son Tay Town.

The town is home to the Duong Lam Ancient Village.

The said village, located a short one-hour drive from Hanoi, is known to have as many as 1,000 traditional Vietnamese-style houses, made from laterite, mud, soil, and rice husks.

Also make time for the many temples and shrines at the village.

Bai Tu Long Bay is a UNESCO-listed Bay, that has forest reserves, limestone caves, and other attractions such as Vung Vieng Village, Tra Gioi Beach, Cong Dam, and Thien Canh Son Cave.

Consider yourself lucky if you spot rare wildlife creatures such as the dugongs, during your cruise through the bay.

Bonus: It is way less crowded with cruise boats than other bays.

Just off the southern coast of Vietnam are the Con Dao Islands, comprising as many as 16 uninhabited islets, that offer breathtakingly beautiful beaches, surrounded by evergreen trees.

The main island, located 230kms from Ho Chi Minh City,offers activities such as snorkeling, swimming, diving, etc.

Try visiting between June and September, and you might get to watch turtles laying eggs.
