10 Best Natural Attractions in Tonga

A must-do on Tonga’s main island, Tongatapu, the Mapua ‘a Vaea Blowholes line an impressive 5 km (3 mi) of coastline.

Watch the waves crashing into and through tiered blowholes, shooting water as high as 30 m (100 ft) into the air when the conditions are right. It’s like nature’s own epic water fountain!

A top snorkelling spot and a hotspot for most boat tours in the Vava’u Group, Swallows Cave is a stunning natural attraction in Tonga.

Carved into the side of Kapa Island, this towering cave provides a safe harbour for large schools of fish, which create mesmerising patterns for snorkellers.

Ok, so Tonga has so many stunning beaches that it would be quite the mission to name them all here, but one well worth mentioning is Houmale’eia Beach in the Ha’apai Group.

Not only is Houmale’eia Beach easy to get to, but it has amazing snorkelling at the 400 m (1,300 ft) long reef. The beach is even backed by a couple of resorts, should you want to stay there or at least pop in for a bite to eat at their restaurants.

Tonga’s largest national park is the obvious go-to for nature. Located on the island of ‘Eua, the ‘Eua National Park can be experienced either by hiking or by taking a 4WD tour.

The national park is home to several natural attractions that we list in Sightseeing on 'Eua: 10 Best Sights & Natural Attractions, including the breathtaking Lokupo and Lau'ua Lookouts, Rats Cave, Giant 'Ovava Tree and more!

While you’re visiting the park, look out for birds like the iconic red shining parrot.

Tours to this site are available with Alakoka Tahi Moana Guest House (Kiko’s) or Off Grid Tonga.

We can’t talk about natural attractions and not mention the whales! Yes, Tonga’s waters provide a safe refuge for humpback whales who migrate from the Antarctic between July and October in order to raise their young.

Not only can you watch these majestic animals from shore, but you can even join a specialised whale swimming tour to snorkel with these gentle giants.

Another interesting formation on ‘Eua, the Lianga Huo ‘a Maui is a natural archway or landbridge carved into the cliffs of the island’s southern coast.

A self-guided walk to visit other natural sights, like the Rock Gardens or Lakufa’anga Cliffs, will bring you to the viewing platform to check out ‘Eua’s natural archway.

See the 50 Best Things to Do on 'Eua for information on the walk to get there.

Some of the most breathtaking views in The Kingdom can be found at the ‘Utula’aina Lookout on the northern coast of ‘Utu Vava’u.

After making your way via rental car or one of the land tours, your reward is a viewpoint across the northern coast of the island with its white-sand beaches, rugged clifftops topped with forest, and turquoise waters.

An elevated platform here makes the viewing all the easier, while the interpretation sign explains how this site was once the residence of the 10th Tu'i Tonga - find out more about this line of kings in A Brief History of Tonga.

Location: Well signposted from the north of Holonga village, 'Utu Vava'u, Vava'u. From Holonga, follow the gravel road north for approximately 1 km (0.6 mi) and turn left at the fork. The lookout is another 650 m (710 yards) down this road.

In Tongatapu is the village of Kolovai where you’ll find tens, even hundreds, of flying foxes residing in colonies in the village’s trees. Visiting this attraction is as easy as walking around the village and looking up at the trees.

It’s well worth it to watch these large fruitbats loving life and making all kinds of crazy noises together.

Finally, for those looking to get well and truly off the beaten track, head to the Hihifo Freshwater Spring. A crystal clear freshwater spring appears to crack open the earth’s surface in Hihifo, the largest village on the far-flung island of Niuatoputapu.

A small set of steps leads into the spring, which begs for a dip! Locals also go to the spring for a swim, so it’s best to wear shorts and a T-shirt to be dressed more modestly.

Location: Western side of Hihifo village, northwest coast of Niuatoputapu, The Niuas.
