Diving with Hawaiian Monk Seals

Niʻihau, known as Hawaii’s "Forbidden Island," sits about 17 miles off Kauai, and since it's privately owned with limited access, the waters around it are some of the most untouched in the state.

That means incredible visibility, dramatic underwater cliffs, and some seriously epic marine life—including the critically endangered Hawaiian monk seal.

With fewer than 1,600 left in the wild, spotting one is rare. But in Niʻihau, if you're lucky, you might share the water with one.

The dive sites here—like Vertical Awareness and Lehua Rock—are next-level, with sheer walls, caves, and crystal-clear blue water. And then there are the monk seals.

Unlike most wildlife that bolts when humans show up, these guys are naturally curious. They’ll glide right up to divers, twist and turn in the water, and sometimes even mimic your movements.

Aside from the seals, Niʻihau’s waters are full of life—schools of colorful reef fish, manta rays, and sometimes even hammerheads cruising by. But the diving here isn’t for beginners.

The currents can be strong, the depths can get deep, and it takes a long boat ride to get there. But if you’re an experienced diver looking for an adventure, few places in Hawaii can top it.

Sharing the ocean with a wild monk seal in one of the most remote dive spots in the world? That’s the kind of moment you never forget.
