Plongée à Ha'apai — Tonga

Ha'apai is Tonga's most remote island group and the epicentre of the kingdom's humpback whale encounters. From July to October, mothers and calves rest in the warm, crystal-clear shallows, allowing permitted snorkellers to swim alongside these gentle giants. The reef diving plays second fiddle but is healthy and uncrowded.
