Get ready to fall in love with the diversity of life and topography Ni’ihau and Lehua Crater have to offer the intrepid diver on this three-tank dive!
The monolithic lava formations in the area provide for an array of habitats. Ni’ihau has the most amazing labyrinth network of lava tubes in the state. The mouths of the tubes are 100 feet wide and extend back 150 feet+, only to drop into another passageway. It’s a truly spectacular sight!
Huge underwater erosional sea caves and arches change the colors around you as you explore this mind-blowing topography. This is the only dive destination in the world where you have an excellent chance to swim with the most endangered marine mammals in U.S. waters, the Hawaiian monk seal.
We mix up our dives sites on this tour, so please refer to the dive site menu for dive site options.
Charter includes: three tanks of air, weights, all meals, drinks, marine ecology tour, snorkeling
Snorkelers/riders along are welcome, though they should understand that the underwater portion of the charter is all about the diver’s safety, so snorkeling options are present but limited. We only take six passengers.
Nitrox package available – If you are not certified in nitrox, that’s okay! We can provide an introduction for an extra fee.
What to Bring
Please bring beach attire, and remember to wear sunscreen and bring a hat and/or sunglasses! Life is bright, so you gotta have shades!
Ni’ihau is considered advanced diving due to its remoteness and the potential diving conditions. Buoyancy control, comfort on the surface while a boat is picking you up, and knowledge of drift diving are necessary. We ask that you have a snorkel with you or rent one from us during your dives. We strongly encourage you to dive with us ahead of a Ni’ihau charter to learn our drift diving techniques. While we take your safety very seriously, we elicit amazing encounters, laugh, and have a grand time!
This trip is weather/seas-dependent, with a 33-mile crossing from harbor to dive site areas. The distance between islands is 17 miles, and it’s usually doable May thru September/October. However, there are weather windows throughout the remaining months when we can make the trip. We offer the service of watching those windows of opportunity and can now offer the trip in the off-season, our favorite being February/March when the mantas are schooling for mating and the humpback whales are numerous.
We keep our group size small — six divers on Dive Rocket and eight divers on Kaimanu. With so few of us getting in the water, the marine mammals, fish, and elasmobranchs (sharks and rays) often come right up to us! With proper diver etiquette advised in advance, you get fantastic photo opportunities found at no other time. This charter is a marine ecology tour, and your guide is with the group at all times pointing out rare species.
This scuba adventure is all about you and your encounters, and we try to put you in the right place at the right time. You can see the sights of a lifetime while snorkeling in the intervals, and that’s what we try to do for you!
