About Trek Alaska

Our backpacking guides can take you places and show you sights that few are ever lucky enough to see. Come with us and go far beyond the tour bus and cruise ship and get up close and personal with a very special wilderness area.

Our commitment to the quality of your experience means individual attention. Group sizes are kept small to ensure a low client/guide ratio with most groups in the 4-5 guest range. Small groups allow for a more intimate encounter with the wilderness.

The Guides

Our Alaska backpacking and hiking guides are skilled and experienced professionals with a depth of outdoor knowledge. They are seasoned guides and instructors of wilderness skills who will help you to meet any challenge. All are trained in wilderness first aid and certified as Wilderness First Responders.

Greg Fensterman, Owner


Greg first fell in love with mountains as a young lad on a Boy Scout backpacking trip to Philmont Scout Ranch in New Mexico. On his way to Alaska he made detour to Washington state where he spent six years exploring extensively in the Cascades of central and northern Washington. He was active in the Seattle branch of the Mountaineers where he instructed in a range of outdoor skills including navigation, route finding, snow shoeing, avalanche awareness and rescue, winter camping, ice ax self arrest and others.

In 2002 Greg moved to Alaska and fell in love with Wrangell-St. Elias on his first trek there which was the Seven Pass route. There was no turning back and the next summer was spent exploring remote routes in the park. Greg has traveled extensively in Wrangell-St. Elias National Park including the pioneering of many new hiking routes in the backcountry of the park. His passion is exploratory treks on untried routes and tries to get in at least one of those each summer.

In the spring of 2008 his book Hiking Alaska's Wrangell-St. Elias National Park was publish by Falcon Guides.

Emily Escapule, Wilderness Backpacking Guide

Emily is enthusiastically coming up on her fifth summer as an Alaska guide. A few years ago she  came to Alaska to work as a glacier guide and there was no turning back.

In 2013 she bought land at mile 46 of the Richardson Highway and built a cabin where she is currently living. Thompson Pass gets one of the biggest snow loads in Alaska, so clearly she likes snow. Snowboarding, ice climbing, hiking, backpacking and glacier exploration are all passions as well as rock climbing and just getting out into the wilderness.

After working as a glacier guide for a few years, her ambition grew beyond day long adventures. She completed the NOLS Instructor Course and is now certified to teach mountaineering courses for them.

Emily is eager to explore the Wrangell Mountains this summer and get into some serious backcountry with Trek Alaska.

Alaska Backpacking and Hiking Guide

Kathryn was born in Nome, Alaska. The daughter of a gold miner she spent her summers playing in remote mining camps around the Seward Peninsula. After years of spending summers in the Last Frontier and winters in California, she made the move North permanent a couple years ago.   

Kathryn left her profession in finance to devote her life to exploring the wilderness full-time. She now chases snow and ice around the state during the winter and guides clients through untouched wilderness in the summer. She has made it her mission to explore the world through climbing trips in the Alaska Range, the Himalaya, Thailand and Canada. This is her second season guiding in Alaska and first with Trek Alaska.

Ian Colgrove, Backcountry Guide


Ian hails originally from Pike County, Ohio but is currently making his home in Bellingham, Washington. This summer will be Ian's fourth season in Alaska; he finds himself drawn back the wild backcountry the state has to offer. A seasoned ornithologist and history nerd, Ian also spends his time eating endless pb&j sandwiches (although he does know how to cook, folks, don't panic). He is an avid rock climber, ice climber, backpacker, trail runner and has recently began an new interest in backcountry skiing. Basically, Ian loves to spend his time exploring new spaces outdoors and staying active. 

Ian has guided multi-day and multi-trip sports in prior Alaskan summers, including sea kayak camping, glacier hiking, and backpacking. From dodging bears in Denali or spitting camels in Morocco, scuba diving in the Bahamas or climbing peaks in the Winds, Ian lives for his next adventure and the good company along the way. As a certified Wilderness First Responder with a Degree in EcoTourism and Adventure Travel, Ian is passionate about leading people into the mountains of Alaska, adventuring with new folks, and guiding them to the best of his ability.
