A view of Thom islet

Just 45km to the east of Hai Phong, Cat Ba boasts crystal-clear waters, jungles and ancient fishing villages. However, the island has managed to keep a relative low profile even though it is just to the south of the world-famous Ha Long Bay. The travel site described Cat Co 2 as “the most relaxed of Cat Ba’s three beaches,” where travelers can take in a panoramic view of the amazing island surrounded by spectacular limestone mountains.

Thrillist also recommended holidaymakers to touch down on Thom islet Beach on the southern coast of Phu Quoc. The beach has avoided the tourist traps and retained its untouched beauty, so not many tourism services can be found there.

"Nestled in the forest that dominates this island, Thom Beach is too far off the beaten track for the coach tourists but brings in enough intrepid backpackers to sustain the local snack shacks and their surprisingly delicious homebrewed beer,” the site said.
