Park Comparison
Katmai & Preserve vs Kenai Fjords
Two iconic parks, different strengths. Here's how they stack up.
Updated
The Quick Take
Katmai & Preserve
Katmai is where you go to watch brown bears catch salmon at Brooks Falls: one of the most concentrated wildlife spectacles on the planet, with dozens of bears fishing the same river bend during peak July runs. Across 5,800 square miles of volcanic wilderness, the park also holds the Valley of Ten Thousand Smokes from the 1912 Novarupta eruption and Mount Katmai's crater lake. The trade-off is access: you fly in by floatplane from King Salmon, lodging is scarce, the campground holds 60 sites, and the season runs essentially June through mid-September.
Kenai Fjords
Kenai Fjords is the most road-accessible glacier experience in Alaska, with Exit Glacier reachable by car from Seward and the Harding Icefield (feeding 40 separate glaciers) viewable on an 8.2-mile climb above it. The boat tours from Seward thread fjords full of sea otters, humpbacks, orcas, and tidewater glaciers calving into salt water. Across 1,416 square miles, you get glacier, mountain, and marine ecosystems on day trips. The trade-off is that the park is mostly water; boat tours sell out, summer weather is wet, and the deep park requires a kayak or charter.
At a Glance
The Crowd Picture
Both parks draw millions, but the crowd experience is different.
Katmai & Preserve
Katmai's 36,000 annual visitors are entirely seasonal: Brooks Camp essentially closes from October through April. July and August concentrate 70 percent of the year's traffic into the bear-viewing platforms, where the park enforces a permit system to manage capacity at the Falls. The 60-site Brooks Camp Campground fills months ahead for those weeks. Stepping away from the bear platforms (a backcountry trip into the Valley of Ten Thousand Smokes, for example) drops you into one of the emptiest wildernesses on the continent.
Kenai Fjords
Kenai Fjords funnels nearly all of its 419,000 annual visitors through Exit Glacier and the Seward boat-tour fleet, both clustered into a four-month window. July alone draws 132,000. The Exit Glacier parking lot fills by 10 a.m. in summer, and popular boat tours sell out a week ahead. The Harding Icefield Trail thins out within the first mile; most visitors turn back at the first glacier viewpoint. Off-season, the park essentially empties; even the road to Exit Glacier closes in winter.

Trails & Activities
Both parks are trail-rich, but they cater to different trip styles.
Katmai & Preserve
Katmai offers 95 miles of trail, but the math is misleading: most visitors hike only the 1.5-mile Brooks Falls Trail to the bear platforms or the 2-mile Naknek Lake Trail. The serious routes are remote and trailless: the 23-mile bus-and-hike day to the Valley of Ten Thousand Smokes, or the multi-day backpack to Mount Katmai's 6,715-foot summit and crater lake. This isn't a trail-hiking park; it's a wildlife park with a few trails, and the wilderness extends in every direction without marked routes.
Kenai Fjords
Kenai Fjords concentrates 50 miles of trail around Exit Glacier. The 1-mile Exit Glacier Trail is paved and accessible, with retreat markers showing how rapidly the ice has shrunk. The 8.2-mile Harding Icefield Trail climbs 3,250 feet through alder, then meadow, then bare rock to a view of the icefield itself: one of Alaska's defining day hikes. Beyond Exit Glacier, most park access is by boat or kayak; Grewingk Glacier and Lowell Glacier require water transport.
Camping
Katmai National Park & Preserve offers significantly more camping options.
