Katmai National Park and Preserve is a natural park and wild reserve of the United States in the south of Alaska, known as the Valley of Ten Thousand Smokes.
Below, you’ll find the ultimate guide to Katmai National Park, including how to get there, when to visit, where to stay, and so much more.
Katmai National Park
Together, the park and preserve cover an area of 4,093,053 acres, roughly the size of Wales. Most of this is an area dedicated to nature and wildlife where hunting is strictly prohibited.
About Katmai National Park
The park was named after the stratovolcano of Mount Katmai.
First, the area was designated as a national monument in 1918 to protect the area created by the great volcanic eruption of 1912 of Novarupta, which formed the Valley with a pyroclastic flow of about 24,710 acres.
The park has 18 individual volcanoes; seven of these volcanoes, since 1900, are still active.
After its designation, the monument was underdeveloped and not visited by tourists until the 1950s.
Initially designated due to its violent volcanic activity, the monument and its surroundings are now appreciated for their abundance of red salmon and brown bears, which feed on these, and a wide variety of Alaskan wildlife.
Katmai is located on the Pacific Ocean side of the Alaska Peninsula, off Kodiak Island in the Shelikof Strait.
The main features of the park are its coast, the Aleutian mountain range, which has a chain of fifteen volcanoes that crosses the southeast region of the park, and a series of large lakes in the western part of the park.
The most significant town closest to the park is King Salmon, where the central offices are located.
The Alaska Peninsula Highway connects Lake Naknek, near the park entrance, to King Salmon, continuing to the mouth of the river at Naknek.
The road is not connected to the Alaska highway system. Access to the interior of the park is by boat through Lake Naknek.
Another road goes from Brooks Camp to Three Forks, which has a view of the Valley of Ten Thousand Smokes.
The 497 miles of coastline runs from the entrance to Cook Cove in Kamishak Bay to the south of Cape Kubugakali. The mountains go from the southwest to the northeast, about 15 miles inland.

Is Katmai National Park worth visiting?
Katmai National Park is one of the most remote parks in America. That being said, those who make the journey here will undoubtedly find it worth the effort.
To really make the trip worthwhile, plan on staying a few days to get the whole experience.
History of Katmai National Park
The area is known today as Katmai National Park and Preserve came into modern history with a big bang. In 1912, the Novarupta erupted - one of the most significant volcanic eruptions in history - forming the Valley of Ten Thousand Smokes.
Before the explosion, the native Alutiiq and Sugpiaq communities called the area home for about 9,000 years. Unfortunately, these groups were forced to resettle after the eruption.
It was declared a National Monument on September 24, 1918, to protect this area.
The national monument was extended three times by presidential proclamation: on April 8, 1942, by Franklin Roosevelt; January 20, 1969, by Lyndon B. Johnson (94,394 acres); and, finally, on December 1, 1978, by Jimmy Carter (1,369,952 acres).
After these series of border expansions, the current park and preserve were established in 1980 under the Alaska National Interest Lands Conservation Act, finally by the Congress of the United States.
The oil spill of the Exxon Valdez company in Prince William Sound on March 24, 1989, produced extensive contamination along the coast of Katmai. By the beginning of April, oil had reached Kenai Fjords National Park.
The spilled oil reached Cape Douglas in Katmai on April 26 and placed south in the next week. In early May, a variety of oil-removing ships were working in the Shelikof Strait; however, 90% of the Katmai coast was contaminated.
The most affected areas were Cape Cjiniak, Chiniak Lagoon, Hallo Bay Beach and its lagoon, Cape Gull, Kaflia Bay, and Cape Douglas. It is estimated that approximately 8400 birds died due to the spill.

The best time to visit Katmai National Park
Although the park is open year-round, most visitors come to catch the iconic bear feeding between June and September.
The summer is also the only time when all park services are in operation, including the main hub at Brooks Camp.
Transportation may also be hard to find during the off-season, but the park remains open for those who make their way here.
Weather and Seasons
Spring
The park begins coming alive again in late May. Temperatures begin to rise, and snowfall continues to melt, but this is still a chilly time to visit and rainy days are not uncommon.
Summer
Summer is undoubtedly the best time to visit Katmai National Park. Early July, in particular, is when most visitors flock here in order to see the bears feeding on salmon from Brooks Falls.
The salmon usually arrive between the end of June and early July, and by August, they are generally far upriver. Summer also tends to have the nicest weather, though it rarely heats up to what most consider hot.
Summer highs usually peak in the low 60s, and nighttime temps often dip below 40 degrees. Pack plenty of layers, and don’t forget your rain jacket as afternoon showers are not uncommon in the summer.
You should also pack plenty of insect repellent if you visit during the summer as black flies and mosquitos are abundant - especially in the backcountry.
Autumn/Fall
Early fall is a great time to visit Katmai. September is your best option if you choose to visit in the autumn, as temperatures are still moderate and most services and transportation options are still up and running.
You might even spot some bears meandering around the lower part of the river at this time.
Winter
While it's technically possible to visit the park in the winter, you will likely have difficulty finding a way to get there. In addition, temperatures are freezing, snowfall is hefty, and no services are available during this time of year.

Top Things to Do in Katmai National Park
Katmai Bears
Katmai is also well known for the brown bear populations and the sockeye salmon. Katmai has the world's largest population of protected bears, estimated at about 2200 bears.
Bears usually congregate at Brooks Falls when salmon are spawning, and many well-known photographers flock to the visitor's platform to take photographs.
Compared to other rivers, salmon arrive early at Brooks Falls. Between 43 and 70 bears were documented in the waterfalls in July, and the same number of bears were seen in the lower part of the river in September.
Coastal areas, such as the Hallo, Kukak, Kuliak, Kaflia, Geographic Harbor, and Chiniak bays, also harbor high densities of bears throughout the year, due to the availability of edible clams and Sedges, as well as salmon and other fish.
It is mainly known for its brown bears, the park with the largest population in the world. Brown bears gather in large numbers in Brooks Falls to catch migratory salmon.
Fed by this rich supply of protein, Katmai's brown bears can grow to large sizes: large males exceed 10 feet and weigh up to one ton.

Hiking in Katmai National Park
Always carry the ten essentials for outdoor survival when exploring.
There are less than five miles of maintained trail inside Katmai, but hikers will still have plenty of opportunities to explore.
Backcountry hiking is allowed, so many choose to “pick their adventure” when it comes to hiking in the park. Below, we’ve highlighted some of the most popular areas and trails.
Brooks Falls Trail - Easy - 1.2 miles - Out & Back
Brooks Falls Trail is perhaps the most trekked mile in the entire park. This flat, easy trail connects Brooks Camp to the bear viewing platforms along Brooks Falls.
You’ll likely see bears before you even reach the falls, as they also use the trail!
If you encounter bears as you hike, keep your distance, make noise, and step off the trail to let them pass if necessary. It’s also a good idea to hike in groups along this short trail.
Cultural Site Trail - Easy - 2 miles - Out & Back
While much of the park’s charm comes from its natural history, its cultural history is also worth noting.
Along this short and easy trail, hikers can learn more about the human history of the park as they stroll past prehistoric camps and a traditional semi-subterranean native dwelling.
Dumpling Mountain Trail - Moderate - 3 miles - Out & Back
This is one of the park’s more challenging routes, though the climb up to the overlook is worth the extra effort.
You’ll pass through boreal forest and alpine tundra before you reach the summit, and the best part is you’ll likely have the trail all to yourself - even in the busy summer months.
The overlook rewards hikers with incredible views of Brooks River, Lake Brooks, and Naknek Lake.
The Valley of Ten Thousand Smokes
If you want a unique experience in Katmai National Park, don’t miss the Valley of Ten Thousand Smokes.
The valley’s otherworldly landscape results from a volcanic eruption, and the park offers a guided tour to help you get the most out of this extraordinary area.
This is a full-day excursion; the bus trip alone takes eight hours.
Once you arrive, you’ll complete a three-mile hike through the ash and pumice that still cover the valley floor.
Tours leave from Brooks Camp.
Backcountry Hiking
After exploring the park’s developed trails, you can head off into the backcountry.
No permits or fees are required for backcountry hiking, though it takes some skill, and hikers should be physically fit.
It is also crucial to know what to do when encountering a bear (which is extremely likely), so don’t miss the bear talk at the visitor center when you arrive.
Brooks Falls is one of the first places in Katmai where salmon are available to bears. Bears numbers at Brooks Falls peak in mid-July.

How can you beat the crowds at Katmai National Park?
The park is open year-round, but 99% of visitors come between May and September.
This is mainly because this is the only time all the services are up and running, and the Bear Viewing is at its best between late June and early July when the salmon migrate from Bristol Bay into park waters.
Your best chance of beating the crowds at Katmai is visiting outside of late June and early July, though that also means you’ll miss most of the park's main draws.
If you hope to see the bears but still want some solitude, consider backcountry camping. That way, you can still see the main attractions AND revel in the complete wilderness that the park is known for.
Where to stay when visiting Katmai National Park
Quite a few lodging options are located inside Katmai National Park, though most will cost you a pretty penny.
If you prefer modern conveniences like running water, a bed, and a restaurant serving tasty meals, these lodges may be worth the steep price.
Most lodging options have limited availability, so plan on booking months in advance if you want to snag a spot. Below, we’ve outlined some of the most popular lodging options inside of Katmai.
Brooks Lodge
Brooks Lodge is in the park's center near the world-famous Brooks River and the beautiful Naknek Lake.
The lodge was originally a fishing camp in the 1950s, but today, it is a beautiful retreat with 16 modern cabins and a main lodge with a large fireplace, restaurant, and bar.
All the cabins are one-room, featuring two sets of bunk beds to accommodate four guests comfortably.
Due to its central location, Brooks Lodge is the most sought-after accommodation inside Katmai National Park, making it extremely hard to get reservations.
The lodge is so popular that they use a lottery system for reservations. Applications for the following year are available online each December.
If you’re not one of the lucky ones who win the lottery, don’t give up.
It’s common for people to cancel their trips, so try calling a few months before your trip to see if any spots have been freed up. Don’t be shy - you may need to call a few times before you have any luck!
Kulik Lodge
Kulik Lodge also started as a fishing retreat and still caters to anglers today.
This historic lodge sits along the beautiful and abundant Kulik River, and you can even book guided fishing tours during your stay.
The lodge has 11 cabins, all outfitted with modern conveniences like electricity and private bathrooms.

Katmai National Park Camping
Brooks Camp is the only designated campground in the park. This is the central hub and the park’s summer headquarters, so pitching your tent here is highly convenient.
Not surprisingly, spots fill up quickly, so make your reservations well in advance.
The campground has no designated campsites but one large communal area that can accommodate up to 60 people.
An electric fence surrounds the area to keep the bears away and features shelters, food storage caches, fire rings, vault toilets, and potable water.
Brooks Camp is open year-round, though only limited services are available between mid-September and May.
If you couldn’t snag a spot at Brooks Camp Campground or seek a more rugged experience, backcountry camping is also allowed at Katmai National Park.
No permits or fees are required - but remember that you are in bear country, so food must always be kept in bear-proof containers.
