Scattered amongst the aquamarine expanse of the southern Pacific, Tonga offers both a taste of eccentric island culture and the chance for memorable aquatic adventures. These warm, reef-dotted seas hark back to a time of classical antipodean exploration – rich in both colourful wildlife and romantic, desert-island intrigue. Nowadays, the region’s largest visitors are also its most fascinating - humpback whales make these waters their playground, mating and calving far away from their frigid Antarctic home.
