September 8, 2023, Three Forks Overlook

Here at the end of the Confluence Trail you can to Three Forks where the Lethe and Windy Creek merge to form the Ukak River, also known as Knife Creek. The water flows downstream from here to Ukak Falls.

The trail through the valley is not difficult, but be sure you are prepared for the river crossing. People have died here before and at the Lethe Crossing near miles 5-6.

From here you get fantastic views of the valley. Mount Katmai erupted in 1912, shattering the peak and giving the valley its name. The trail leads to a waterfall along the Lethe at mile 6, and from there there is no official marked path. You can push on to a dilapidated hut, lakes at the base of Mageik, Katmai Pass, Novarupta, Mount Griggs, and more.

The trail descends from the park road steeply and passes through cow parsnip which can grow 3-8 feet tall. You may want to wear long pants for this section due to the underbrush. After about a mile and a half the trail flattens out and opens up into the valley. The trail skirts the base of the peaks and gets more sandy and less rocky as you climb.

The two-tiered Brooks Falls viewing platform is the most popular place to be in Katmai National Park, because it offers great overlooks of the biggest and most dominant bears fishing around the waterfall. It can get crowded in July, so you should expect to wait a while before being allowed onto the platform. Your time on the platform may also be limited, usually to about an hour. There are restrictions on tripod use as well.

September 8, 2023, Riffles in Brooks River

The most dominant bears tend to do their fishing around Brooks Falls, visible from the Falls viewing platform. However the Riffles platform, situated about 100 yards downstream from the Falls platform, has some advantages. There is usually no time limit for occupancy, and you are allowed to use tripods here. It's also a great place to watch sows teaching their cubs how to fish, and subadults trying out their new skills. You can view bears fishing in the Riffles via a NPS webcam: explore.org/livecams/brown-bears/brown-bear-salmon-cam-the-riffles

September 8, 2023, Brooks Lake Picnic Area

This picnic area on the shores of Brooks Lake offers a vault toilet, food cache, and covered cooking/eating area. The lake outlet, near the picnic area, is a good place for salmon-viewing in August and September. Sometimes you'll see bears fishing here, too. Human anglers also use this area as a starting point to access the upper Brooks River.

September 8, 2023, Ukak Falls

Ukak Falls, a mighty cascade of ash-laden water, is one of the common destinations on ranger-led hikes from the Robert F. Griggs Visitor Center in Katmai National Park. Use caution if you wander near the canyon rim β€” its edge can be unstable.
