A salt-dome island in the Strait of Hormuz whose soil comes in seventy colours, with a red beach that stains the sea, rainbow valleys and a 16th-century Portuguese fort.

Hormuz is a salt dome pushed up through the seabed, and the salt has brought up iron oxides, clays and minerals that weather into red, ochre, yellow, silver and blue-grey layers. The Red Beach is coloured by hematite; the Rainbow Valley shows a dozen bands in one cliff. Salt caves and the Salt Goddess formation are on the west coast. The Portuguese fort at the north end dates from 1507.

The island is 42 km around; a day by tuk-tuk covers the main sites.

Why it stays quiet

Iranian visitors come during the Nowruz holiday in March. The rest of the cool season the island is quiet, and foreign visitors are rare.
