The park is mostly renowned for the grizzly bear population which is the largest in the world.  There are approximately 2,200 grizzly bears living within the protected area.  One of the best places to see them is from the observation deck at Brooks Falls.

As many as 70 bears have been documented to visit the falls for fishing the spawning salmon.  One of the most intriguing parts of this experience is identifying the different techniques that each of the bears employs to catch their own fish.

Bears are plentiful, however, some of the most populous areas of the park include Chiniak Bay, Geographic Harbor, Hallo Bay, Kaflia Bay, Kukak Bay, and Kuliak Bay.  The majority of visiting people head to Brooks Camp, which is one of the main developed areas in the park.

Katmai is wilderness and the majority of people are more adventurous in their engagement with what it has to offer.  Typical activities include backpacking, camping, hiking, kayaking, and cross-country skiing during the winter months.


The Katmai area is renowned for grizzly bears and just seeing one is a highlight for most people.  However, the highlights are abundant in Katmai when it comes to grizzly bears.

The area is also abundant with sockeye salmon and one of the most remarkable experiences in sitting in the observation area and watching a group of grizzly bears fishing the rivers for salmon.

The Brooks Falls viewing platform is the place to be when the salmon are spawning upriver.  The majority of videos and pictures of bears fishing come from this region.  The best months for viewing bears occur between July and September.

Although grizzly bears are the highlight, there are another 28 species of mammals found within the park boundaries.  Birdwatchers can keep eyes open for the 137 species of birds that fill the skies.  The majestic bald eagle is a coveted sighting.
