Each of Niue’s sea tracks—trails that connect scenic and serene natural spots around the island—offers its own charms to discover with a picnic, a camera and a snorkel. The Talava Arches are among the most spectacular landmarks, and the maze of caves, rock pools and coral formations are worth the half-hour rugged and sometimes slippery hike (take sturdy footwear) to the arches. After you’ve been sated with Pacific Ocean and marine life views, it’s an easy walk to the Matapa Chasm, once the swimming spot of Niuean kings. The pool there is sheltered and quiet, ideal for a refreshing swim and very safe for snorkeling.
