Black Pebble Beach, New Zealand.

Eljas told Business Insider: "Found just north of Kaikoura, Black Pebble beach on New Zealand’s South Island is one of the country’s most unique beaches — and although it’s not far from the tourist trail, other travellers rarely visit. The beach itself is made up of little black pebbles, while rock formations emerge from the foaming waters. Plus on clear days, travellers can spot the snow-capped peaks of the Southern Alps in the distance."
