Niue is a small island nation in the South Pacific Ocean. It’s known for its limestone cliffs and coral-reef dive sites. Migrating whales swim in Niue's waters between July and October. In the southeast is the Huvalu Forest Conservation Area, where trails through fossilized coral forests lead to the Togo and Vaikona chasms. The northwest is home to the rock pools of Avaiki Cave and the naturally formed Talava Arches.
