He was part owner of an Arctic tour business for 10 years and has guided sea kayaking trips in Prince William Sound, polar and brown bear trips, and birding trips.

His true passion is natural history and sharing that passion with participants, and he loves to have fun!

Detailed Itinerary

A glimpse into our journey

Prince William Sound aboard the Discovery

Jun 18-21

You’ll travel to the small port town of Whittier on the western side of Prince William Sound to rendezvous with the Discovery and begin your five-day voyage through breathtaking glacial scenery, blue icebergs, and spectacular marine life. Lush vegetation drapes the hillsides in green as streaming waterfalls cascade down the rocky cliffs. Harbor seals hauled out on the flotillas of icebergs and bald eagles perched atop trees watch as the Discovery navigates the icy, blue waters. You’ll search for marine mammals such as sea otters, often seen sunbathing on icebergs or carrying young on their bellies as they swim. Listen to the cracks, pops, and thunderous roars of calving glaciers while the Discovery drifts silently by these active rivers of ice.

Prince William Sound is surrounded by the northern-most temperate rainforest in the world and many land mammals are also present, though not always easy to spot. You’ll hike on shore among the wildflowers and also kayak for a water-level view of the wonders of the sound. Whale watching will be another exciting and unpredictable experience as many whales, especially humpbacks, are found in the region.

Prince William Sound to Anchorage

Jun 22

You will wake to some of the world’s most spectacular scenery with sprawling glaciers and a panoramic skyline of mountain grandeur. After disembarking, you’ll follow the Turnagain Arm of the Cook Inlet to return to Anchorage. Be sure to keep an eye out for the occasional family of Dall sheep on the cliffs above.


From calving glaciers to breaching humpback whales, every day on Prince William Sound is full of highlights.

You are visiting the northernmost coastal temperate rainforest in the world so expect some rain. That said, this time of the summer tends to have some of the driest weather. Daytime temperatures may be as high as 70°F, but 60’s°F are more typical with night temperatures in the 50’s°F. We may visit multiple tidewater glaciers where cool breezes descend from the glaciers, so be prepared with a hat and gloves. The Discovery loans you rubber boots and warm rubberized gloves for kayaking and glacier visits where it may be raining, and high-quality rain jackets and pants. Bring sunscreen for those warm, sunny days.

Fitness Level

Our voyage in Prince William Sound will include landings and opportunities to hike on shore, typically no more than a mile or two on varying terrain. Walks and hikes are generally at a slow pace with stops for observation and photography and may be skipped by anyone that is not interested or able. Kayaking is also an option. Please contact us if you have any health concerns that may make this trip challenging.


Airfare is not included in trip costs. Detailed logistical information and the contact information for our recommended flight-ticketing agent are included in the Trip Materials we will send you.

Flights you (or a travel agent) book: Arrive in Anchorage, Alaska (ANC) by June 17. If you are arriving from our Denali Spring Wildlife and Wildflowers Safari, see Flights section in its itinerary for arrival information. Depart from Anchorage anytime on June 23. If you are continuing on our Coastal Brown Bears of Silver Salmon Creek, see Flights section in its itinerary for departure information.



Each of the Discovery cabins has bunk beds, a small clothing closet, and drawers for your personal belongings; the two shared bathrooms provide complete facilities including a hot shower. Additional Discovery guests may join our group for just this Prince William Sound portion of our safari. See our website for more details about the Discovery.


Don’t let a fear of seasickness scare you away! For all but the most sensitive, seasickness is rarely a problem in this region. It’s a good idea to bring medication if you get seasick or are unsure, but you may find that you do not need it after a couple days once you have your “sea legs.” Even those who have experienced seasickness reported that the incredible wildlife and overall experience were well worth the temporary discomfort. Read our suggestions for coping with seasickness at and contact us if you have any concerns.



  • Non-smoking policy: We have a strict non-smoking policy. Smoking is not permitted at any time or any place during our tours.
  • Maximum time in nature: We try to spend as much time in nature as possible, sometimes resulting in long days but giving you a more in-depth experience.
  • Itinerary route: The itinerary route, stops, and plans are subject to change by unforeseen circumstances beyond our control, such as weather or road conditions.
  • Additional forms: For some of our tours, you may be asked to fill out additional forms (e.g., medical questionnaire).
  • Medical conditions and travel risks: Travel to remote places is exciting, but it is important to understand and accept the risks, both medical and logistical. Minor medical problems can usually be treated, but because we are often far from medical facilities, there can be no expectation for immediate medical treatment or evacuation, even in cases of trauma. Anyone with health problems needing close medical supervision should not consider going on this tour. Bring enough medication for the duration of the trip for any chronic medical needs since pharmacies are usually not available. When you send your deposit and signed Reservation/Release Form, you certify to us that you do not knowingly have any physical or other conditions that would create a risk for yourself or for other trip participants.
  • Use of drones/UAVs on tours: Unmanned Aerial Vehicles (UAVs), AKA drones, are not suitable for use on most Cheesemans’ Ecology expeditions due to logistical constraints and in many cases, local and national laws or regulations. In some cases, such as on our polar voyages, we operate under environmental regulations that ban the use of recreational drones. Do not bring a drone on safari without contacting us first.
