Mission Statement

Emerald Air Service exists to educate our guests about Katmai's majestic residents, the Coastal Brown Bear, and the country in which they live. We hope that everyone who takes one of our trips leaves with, not only great photographs, but with an understanding of bears, knowledge of how to move through their world, and a love for all wild places.

Our History

Emerald Air Service was founded in 1991 by Chris and Ken Day. The newly wed couple set out to build a life doing what they loved together. And they succeeded—pioneering the guided bear viewing day trip industry in Alaska while touching thousands of lives as they shared this corner of Alaska and the Katmai bears. They retired in 2009, selling their business to Craig and Sarah Elg—excellent custodians of Chris and Ken's legacy. In 2019, Emerald Air Service found a new owner in Chris Freeman, whose love for all things Alaskan gave him the ambition to own not just any bear viewing company, but this one. With his energetic vision, Emerald Air Service's fleet has grown and now has a state of the art dock and lovely cabins—including the main office—on the quiet shores of Beluga Lake.

Meet Our Guides

Naturalist guides are at the heart of Emerald Air Service's mission. All EAS guides are trained and certified in First Aid/CPR; have completed the Katmai Service Provider's Bear Viewing Guide Excellence program; and continue their education together in in-house naturalist training, always building on their skills and knowledge of Katmai's ecosystem and bear biology. Nothing is more rewarding than seeing understanding and love for the bears and this country spread to our guests—and our guides' passion is infectious!

Upon retiring from the Navy after 22 years stationed all around the world, including a tour in Afghanistan, he was hired on with Hallo Bay Wilderness Lodge out of Homer, Alaska, where he was trained as a Naturalist Guide. During his tenure there, he rose to the position of lead guide and then in 2018 joined the Emerald Air Service team as our lead Naturalist Guide.  Lance has been guiding in Katmai and Lake Clark National Parks for 9 years and truly enjoys the work he does in the field and teaching people about the wonders of the park.

Bear Viewing Philosophy

What sets Emerald Air Service's Bear Guides Apart from Other Bear Viewing Operators?
Basically "bear etiquette"—the bears come first. At Emerald Air Service, we follow our simple philosophy, that this is the bears' world and we are only guests in it for a short period of time, and need to behave that way. Our goal is to not disturb any bears while in the field. If we do, then we did something wrong. In addition to bear viewing, we also strive to educate our guests' on everything bears—from behavior, lifecycle, reproduction, taxonomy, seasonal diet, to denning, etc.—not just go out and see a bear. There is also all the other flora and fauna, geology, and history of the area that are incredible. When out in bear country, we use proven techniques that have been passed down from guide to guide at Emerald Air Service.

Our Aircraft

The DHC-3 Otter was manufactured between 1951 and 1967, and aviation has not been able to improve on this ideal bush aircraft. Emerald Air Service is fortunate enough to own two de Havilland Otters. These classic planes (manufactured in 1958 and 1962) have been upgraded to have state of the art turbine engines for even greater power, speed, and safety.


Features of our DHC-3 Otters


Each aircraft seats up to 10 people + pilot


Every passenger has their own spacious seat, window, and headset.


We operator on floats for greatest safety flying over the Cook Inlet and unparalleled access to the remote corners of Katmai.


All EAS aircraft are equipped with ADS-B (Automatic Dependent Surveillance-Broadcast) and Spidertracks for constant flight monitoring.


Perfect Safety Record

In 30 years of operation, Emerald Air Service has never had an accident. This is due to a tireless commitment to excellence, safety, and sound judgement regarding Alaska's unique, powerful combination of natural forces.
