Fat Bear Week 2025: A Celebration of Nature’s Giants at Katmai National Park

The anticipation is building as the bracket for Fat Bear Week 2025 has been unveiled, showcasing 12 remarkable brown bears from Katmai National Park and Preserve in Alaska. This beloved annual event invites global participation, allowing fans to vote for their favorite bear, culminating in the crowning of the “fattest bear” of the year. The voting period runs from September 23 to September 30, with online ballots open daily from 12 PM to 9 PM ET.

The Origins of Fat Bear Week

Fat Bear Week began in 2014 as a modest one-day event, initiated by Mike Fitz, a former park ranger and resident naturalist at Explore.org. Fitz noticed the stark transformation in the bears’ size as they prepared for hibernation, prompting him to create a platform that would highlight these magnificent creatures. Sarah Bruce, a park ranger at Katmai, emphasized the importance of this event, stating, “It’s a really great way to kind of showcase these bears that we have in southwest Alaska.” The event has since evolved into a week-long celebration, making the remote park more accessible to those unable to visit in person.

The Bears’ Remarkable Weight Gain

As winter approaches, these bears can gain an astonishing 700 pounds, with some reaching weights exceeding 1,400 pounds. Bruce explained, “A fat bear is a healthy bear,” underscoring the critical role that fat reserves play in their survival during hibernation. Over a span of five to six months, these bears consume a year’s worth of food, preparing for the harsh winter months when they will not eat.

The winner of Fat Bear Week receives no tangible prize; rather, their victory signifies their ability to survive another winter, a feat that is both challenging and vital for their species.

Meet the Contenders for 2025

The contenders for this year’s competition were announced during a livestream event, a stark contrast to last year’s bracket reveal, which was delayed due to a tragic incident involving two grizzlies. While approximately 80 bears frequent the Brooks River during the active season, only 12 are selected based on specific criteria, including photographic evidence of their size transformation.
