The northernmost of the seven United Arab Emirates, Ras Al Khaimah—sometimes abbreviated to RAK—is often overlooked in favor of neighboring Dubai and Abu Dhabi, which has afforded the emirate something of an undiscovered-gem status. It, too, has an enviable waterfront and glitzy beach resorts, although there are plenty more things to do in Ras Al Khaimah, from exploring the varied topography of the Hajar Mountains and visiting the lofty peak (and supposedly world’s longest zipline) of Jebel Jais, to Bedouin cultural excursions deep into the desert and plenty of adventure-sport offerings.
