Alaska offers some of the world's best cold water diving, featuring stunning scenery and spectacular animal sightings above and below the ocean's surface. You will be surprised of what you can see in Alaska. Divers can spot seals, orcas, humpbacks, wolf eels, octopus, and even explore an exciting wreck!

Intro To Alaska

Alaska is an extraordinarily beautiful place offering wonderful wildlife above and below water, beautiful sceneries, wide open spaces, mountains, rivers, and glaciers. It's a great destination for all nature lovers.

Marine Life In Alaska

Due to all the nutrients in the water, and the lack of pollutants, there is a shocking amount of life up north - contrary to popular belief. Halibut, octopus,rock fish, ling cod, sea lions, spawning salmon, and humpbacks to name a few.

Diving Conditions

Visibility drastically varies depending ondive sites. You can expect to see anywhere between 25 - 80 feet. Keep in mind that when visibility is worse, it is due to upwellings of nutrients - which then pulls in the marine life - so not necessarily a bad thing! Currents can be quite strong, so it is best to time your dives during slack tide (which operators will typically doanyways).

How To Get To Alaska

The main airport in Alaska is the Anchorage International Airport (ANC). Nevertheless, there are several other international airports with connecting flights to the USA and Europe.

Katie is the most experienced travel advisor at Bluewater Travel, having been with the company since its inception. Her interest in scuba diving started many years ago while on vacation in the British Virgin Islands. Though not yet certified, she was mesmerized by the marine life below the surface. As soon as she returned to Los Angeles, she swapped her mask and snorkel for a regulator and BCD (and a mountain of other dive equipment) and hasn't looked back since! 

Katie is no stranger to the Southern California waters, but prefers to travel around the world and experience new cultures, food, and marine environments. She has visited and led trips to many of the top liveaboard destinations. Her most memorable dive moment was swimming 20 feet from humpback whales off the coast of Moorea. At the top of the list for her next dive vacation: Alor. 

When she's not in the office, you're likely to find Katie attending a concert in LA, snowboarding at Mammoth, attending to Sadie, or cheering on her alma mater, The Michigan Wolverines. Go Blue!

One of the best destinations for hiking and marveling at fabulous scenery. You will almost always see bears, mice, all sorts of little critters, and lots of bald eagles. The Kenai is not overrun with people, making it a great destination when you want to get away from busy daily life.

Alaska is the best kept diving experience secret on the planet. I gave it 3 stars for conditions because in the winter, topside conditions can be challenging.Places like Seward, Whittier, Sitka, Juneau, Ketchikan and Kodiak offers a different dive experience from what you are probably used to. Yes it is cold water diving year 'round and dry suit qualifications are a must. But if you would like to try some challenging and exciting diving you might give Alaska a try.Yes we dive year round in Alaska and no it is not always under ice. Water temps are around 40F in the winter and can reach 60F in the summer. And if you want some under ice diving well that can be found year round also.There are available trips around the state such as a challenging trip to Ketchikan in February of 2014, salmon shark adventures and trips to Prince William Sound and Sitka.Look at the pictures to see the variety of diving experiences. Wrecks, caverns, octopus, sea lions, orcas and a broad spectrum of smaller sea life.The easiest and least expensive way to try some Alaska diving is to come to Anchorage. Dive Alaska in Anchorage, The SCUBA Tank in Juneau and the Deep Six Dive Center in Ketchikan are fine shops. Be very careful at any others. Some cater to commercial divers and some only want to separate you from your money.Diving in Alaska is worth the trip. You can see moose, elk, musk ox and bears when you are topside.
