Top 3 things to do in Tonga

Swim with Humpback Whales

Tonga is one of the few places in the world where you can swim alongside humpback whales in their natural habitat. Between July and October, these majestic creatures migrate to Tonga’s warm waters to give birth. Guided whale-watching and snorkelling tours allow visitors to have an unforgettable experience up close with these gentle giants. Watching them breach and hearing their haunting songs underwater is truly a once-in-a-lifetime adventure.

Explore the Stunning Haʻapai Islands

For those looking to escape the crowds, the Haʻapai Islands offer secluded beaches, crystal-clear waters, and a laid-back atmosphere. This untouched paradise is perfect for snorkelling, diving, and kayaking. Visitors can explore pristine coral reefs, interact with friendly locals, and enjoy some of the most unspoiled landscapes in the South Pacific. Whether you’re island-hopping or simply relaxing in a hammock, Haʻapai is an ideal destination for travellers seeking tranquillity and adventure.

Visit the Ancient Haʻamonga ʻa Maui Trilithon

Sometimes referred to as the ‘Stonehenge of the Pacific,’ the Haʻamonga ʻa Maui Trilithon is a fascinating megalithic structure built in the 13th century. Made of massive coral limestone slabs, it is believed to have been used as an ancient astronomical calendar or a royal gateway. Located on Tongatapu, this site provides insight into Tonga’s rich history and ancient Polynesian engineering skills.
