Katmai National Park and Preserve is a United States national park and preserve in southwest Alaska, notable for the Valley of Ten Thousand Smokes and for its brown bears. The park and preserve encompass 4,093,077 acres (6,395.43 sq mi; 16,564.09 km2), which is between the sizes of Connecticut and New Jersey. Most of the national park is a designated wilderness area.

 

The park is named after Mount Katmai, its centerpiece stratovolcano. The park is located on the Alaska Peninsula, across from Kodiak Island, with headquarters in nearby King Salmon, about 290 miles (470 km) southwest of Anchorage. The area was first designated a national monument in 1918 to protect the area around the major 1912 volcanic eruption of Novarupta, which formed the Valley of Ten Thousand Smokes, a 40-square-mile (100 km2), 100-to-700-foot-deep (30 to 213 m) pyroclastic flow. The park includes as many as 18 individual volcanoes, seven of which have been active since 1900.

 

Initially designated because of its volcanic history, the monument was left undeveloped and largely unvisited until the 1950s. The monument and surrounding lands became appreciated for their wide variety of wildlife, including an abundance of sockeye salmon and the brown bears that feed upon them. After a series of boundary expansions, the present national park and preserve were established in 1980 under the Alaska National Interest Lands Conservation Act.

Katmai National Park and Preserve offers spectacular bear viewing opportunities.

 

It is important that all who visit Katmai respect bears and are armed with the knowledge to stay safe in bear country. The urge to take the perfect photograph or maintain the best fishing hole with your fly rod can be strong, but bears need space to sleep, eat, rest, travel, and play.

There are more than 2,000 grizzlies living in this wilderness on the Alaska Peninsula, and each adult can grow to more than 1,000 pounds. That's a lot of weight for Katmai National Park to bear, especially adding the nearly 40,000 humans a year who pay a visit as the Brooks River swells with countless salmon. Bears can be spotted fishing for their fill along the river in the summer and fall, gorging on sockeye to fatten up for hibernation. You don't have to trek all the way to Alaska to observe them, though: Staycationers can get a great view of the feeding frenzy via webcam.
