According to Smarter Travel, Ha Long bay has more than 1,500 islands and inlets jutting out of the turquoise waters. Travelers should take one of overnight cruises offered within the bay and watch the sunset over its tranquil waters.

“Son Doong Cave is the largest cave in the world— more than 5.5 miles long and has its own jungle and river and yet it wasn't even discovered until 1991, or fully explored until 2009,” said the tourism site.

Smarter Travel described Can Gio as “wetlands support not only thousands of mangroves, but also around 200 different species of wildlife and 150 species of flora./.”
