Tau Island, part of Tongatapu’s off-shore islands, is a delightful destination for snorkelling and whale watching, particularly accessible to yachties (for free). This small island is encircled by a thick sandy beach and features a central coconut grove. Its pristine waters and tranquil setting make it a perfect spot for a day trip from Nuku'alofa, particularly with whale-watching tours, offering visitors a taste of Tonga's natural beauty and oceanic wonders.
