Alaska: America's Last Great Wilderness (Complete Adventure Guide)

Alaska is 1.7 million square kilometers — larger than all of Western Europe — with a road network of 24,000km. The math tells you immediately: most of Alaska is inaccessible by road. Getting to the extraordinary parts requires small planes, boats, or extended hiking. The inaccessibility is the point.

Denali National Park

Denali National Park has one road — 148km long — and private vehicles are restricted to the first 24km. Everyone beyond that travels by park bus. The road crosses the taiga and tundra of the Alaska Range, with Denali (6,190m — North America's highest peak) visible on clear days from multiple sections.

Wildlife: Denali's wildlife density is extraordinary — grizzly bears, moose, caribou, Dall sheep, wolves, and golden eagles are all regularly seen from the park road. The Alaska Range provides a spectacular backdrop.

Climbing Denali: 1,200 people attempt the summit each year; approximately 50% summit. The standard West Buttress route takes 17-21 days. Requires mountaineering experience, a permit ($400), and registration with the National Park Service.

Flightseeing: A glacier landing flight (60-90 minutes, landing on one of the Alaska Range glaciers) from Talkeetna delivers the most dramatic mountain scenery in North America. Operating companies: K2 Aviation, Talkeetna Air Taxi.

Kenai Fjords National Park

Southeast of Anchorage, accessible from Seward. Tidewater glaciers calving directly into the ocean, humpback whales in Resurrection Bay, black bears on the shoreline, and more Steller sea lions on a single rock than you have ever seen in one place.

Exit Glacier: The most accessible glacier in Alaska — a 1-mile walk to the ice face, longer hikes to the Harding Icefield. The recession stake markers (showing the glacier's position in each decade) document climate change more viscerally than any graph.

Boat tours: Full-day Kenai Fjords boat tours from Seward visit the Harding Icefield glaciers, sea bird colonies on the Chiswell Islands, and open-water whale-watching. Major Marin, Kenai Fjords Tours, and Sunny Cove Sea Kayaking operate from Seward.

Katmai and the Brown Bears

Katmai National Park is accessible only by floatplane from King Salmon (3 hours from Anchorage by commercial flight) or charter from Homer. The reason to go: Brooks Falls, where approximately 100 brown bears congregate to catch sockeye salmon leaping upstream July-October.

Brooks Falls is one of the world's great wildlife spectacles — bears at the falls' lip catching salmon mid-air, bears lying in the river as salmon bounce off their faces. The Katmai bear cam (accessible online) provides year-round viewing; being there in person is an entirely different level of experience.

Logistics: NPS cabins at Brooks Camp must be booked months in advance through recreation.gov (they sell out within minutes of release). Floatplane charter from King Salmon: $550-700 per person roundtrip.

The Inside Passage and Southeast Alaska

Juneau: Alaska's capital, accessible only by sea or air. The Mendenhall Glacier is 20 minutes from downtown — a tidewater glacier (receding dramatically) that can be approached on foot.

Glacier Bay National Park: One of the most rapidly advancing and receding glacial systems in the world. The tidewater glaciers of the bay calve icebergs while humpback whales surface in the fjords below. Cruise ships access the bay; NPS-permitted kayaking expeditions provide a more intimate experience.

Sitka: Former capital of Russian Alaska. The Russian Orthodox Saint Michael's Cathedral in the center of town, the Sitka National Historical Park (Tlingit totem poles), and the extraordinary ocean views.

Practical Alaska Tips

Getting there: Alaska Airlines dominates internal Alaska routes. From Anchorage, small plane access to the park towns (Kenai, Kodiak, Cold Bay) is via Ravn Alaska or Grant Aviation.

Best time: June-September for most destinations. July is peak for wildlife (brown bears fishing for salmon at Brooks Falls). September is extraordinary for fall colors and fewer tourists.

Bear safety: Mandatory bear awareness. In national parks, bear canisters are required for backcountry food storage. Bear spray is essential. The bears of Alaska are not habituated to food rewards — they remain wild and generally avoid humans if given space.
