Phu Ninh Lake: Quang Nam’s ‘Miniature Ha Long’ and Hot Springs

Looking for nature, islands and a soak in warm mineral water, all in one trip? Phu Ninh Lake — a vast emerald reservoir dotted with islands south of Hoi An — is one of Quang Nam’s loveliest eco-escapes, nicknamed the region’s “miniature Ha Long.”

What is Phu Ninh Lake?

Phu Ninh is a huge man-made lake ringed by forest and scattered with around 30 islands of all shapes and sizes, from Turtle Island to Monkey Island. It’s been developed into an eco-tourism area where you can take a boat between the islands, camp by the water, hike the surrounding hills and picnic in peaceful, green surroundings.

The hot mineral spring at Phu Ninh Lake

A highlight is the on-site hot mineral spring. Pumped up from deep underground and rich in minerals, the warm water is a relaxing way to round off a day of boating and walking — a natural spa in the heart of the countryside.

The reservoir spreads over roughly 30 square kilometres and is dotted with around 30 little islands, which is how it earned its “miniature Ha Long” nickname. For planning ideas around the wider province, the Vietnam national tourism guide is a useful reference before you set off for Phu Ninh Lake.

How far is it from Hoi An?

Phu Ninh sits near Tam Ky, around 45 kilometres south of Hoi An — about an hour’s ride down the coast and inland. It pairs well with other southern Quang Nam stops on a longer day out.
