At the far northeastern tip of Arabia exists a landscape like no other. Separated from Oman proper by the United Arab Emirates, the Musandam Peninsula reaches toward Iran and into the notorious Strait of Hormuz with delicate, dramatic mountains of barren red rock falling into an emerald sea.

These are the only desert fjords in the world.

Known locally as khors, these jagged coves were created by the collision of tectonic plates instead of the glacial activity that shaped their Nordic and Alaskan cousins. But the uncanny similarities still persist with 6,500-foot (2,000-meter) mountains and razor-thin spines of rock towering over deep water teeming with wildlife. Dolphins, rays, and a variety of colorful reef fish can be found throughout the inlets, and the warm, clear water makes for excellent scuba diving and snorkeling.

Easily explored in a day trip from the town of Kasab, most excursions will be aboard a traditional fishing vessel known as a dhow. Between vibrant local history lessons and fascinating facts of geography, guides may even free dive for scallops freshly served as ceviche with a bit of lemon and spices.
