Mountains include Denali in the Alaska Range, the Wrangell Mountains, and the Ray Mountains. The native people of the interior are Alaskan Athabaskans. The largest city in the interior is Fairbanks, Alaska's second-largest city, in the Tanana Valley. Other towns include North Pole, just southeast of Fairbanks, Eagle, Tok, Glennallen, Delta Junction, Nenana, Anderson, Healy and Cantwell. The interior region has an estimated population of 113,154.

The Alaska Range is a relatively narrow, 600-mile-long (950 km) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest end to the White River in Canada's Yukon Territory in the southeast. The highest mountain in North America, Denali, is in the Alaska Range. It is part of the American Cordillera.
Denali National Park and Preserve, formerly known as Mount McKinley National Park, is an American national park and preserve located in Interior Alaska, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompass 6,045,153 acres which is larger than the state of New Hampshire. On December 2, 1980, 2,146,580-acre Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga, with tundra at middle elevations, and glaciers, snow, and bare rock at the highest elevations. The longest glacier is the Kahiltna Glacier. Wintertime activities include dog sledding, cross-country skiing, and snowmobiling. The park received 594,660 recreational visitors in 2018.
The Nenana River is a tributary of the Tanana River, approximately 140 miles (230 km) long, in central Alaska in the United States. It drains an area on the north slope of the Alaska Range on the south edge of the Tanana Valley southwest of Fairbanks.
The Glenn Highway is a highway in the U.S. state of Alaska, extending 179 miles (288 km) from Anchorage near Merrill Field to Glennallen on the Richardson Highway. The Tok Cut-Off is often considered part of the Glenn Highway, for a total length of 328 miles (528 km).
The George Parks Highway, usually called simply the Parks Highway, runs 323 miles (520 km) from the Glenn Highway 35 miles (56 km) north of Anchorage to Fairbanks in the Alaska Interior. The highway, originally known as the Anchorage-Fairbanks Highway, was completed in 1971, and given its current name in 1975.
The Alaska Railroad is a Class II railroad that operates freight and passenger trains in the state of Alaska. The railroad's mainline is over 470 miles (760 km) long and runs between Seward on the southern coast and Fairbanks, near the center of the state and the Arctic Circle, passing through Anchorage and Denali National Park where 17% of visitors arrive by train. The railroad has about 656 miles (1,056 km) of track, including sidings, rail yards and branch lines, including the branch to Whittier, where the railroad interchanges freight railcars with the contiguous United States via rail barges that sail between the Port of Whittier and Harbor Island in Seattle.
The Edgerton Highway is a minor highway in the U.S. state of Alaska that extends 33 miles (53 km) from the Richardson Highway near Copper Center to the town of Chitina. The McCarthy Road, within the Wrangell-Saint Elias National Park and Preserve, is a 58-mile (93 km) extension from Chitina to McCarthy.
The Iditarod Trail, also known historically as the Seward-to-Nome Trail, is a thousand-plus mile (1,600 km) historic and contemporary trail system in the US state of Alaska. The trail began as a composite of trails established by Alaskan native peoples. Its route crossed several mountain ranges and valleys and passed through numerous historical settlements en route from Seward to Nome. The discovery of gold around Nome brought thousands of people over this route beginning in 1908. Roadhouses for people and dog barns sprang up every 20 or so miles. By 1918 World War I and the lack of 'gold fever' resulted in far less travel. The trail might have been forgotten except for the 1925 diphtheria outbreak in Nome. In one of the final great feats of dog sleds, twenty drivers and teams carried the life-saving serum 674 miles (1,085 km) in 127 hours. Today, the Iditarod Trail Sled Dog Race serves to commemorate the part the trail and its dog sleds played in the development of Alaska, and the route and a series of connecting trails have been designated Iditarod National Historic Trail.
The Gulkana River is a 60-mile (97 km) tributary of the Copper River in the U.S. state of Alaska. Beginning near the southeastern end of Summit Lake in the Alaska Range, the river flows generally south to meet the larger river 9 miles (14 km) northeast of Glennallen. The Richardson Highway and the Trans-Alaska Pipeline run north–south, nearby and roughly parallel to the Gulkana River. Slightly south of Summit Lake the river passes under the east–west Denali Highway near its junction with the Richardson Highway at Paxson.
Denali State Park is a 325,240-acre (131,620 ha) state park in the U.S. state of Alaska. It is located in the Matanuska-Susitna Borough adjacent to the east side of Denali National Park and Preserve, along the Parks Highway.
The Stampede Trail is a remote road and trail located in the Denali Borough in the U.S. state of Alaska. Apart from a paved or maintained gravel road for 8 miles (13 km) between Eight Mile Lake and the trail's eastern end, the route consists of a primitive and at times dangerous hiking or ATV trail following the path of the original road, which has deteriorated over the years. The route ends at an abandoned antimony mine at 63.740739°N 150.379229°W along Stampede Creek, a couple miles past Stampede Airport's grass airstrip.

The Teklanika River is a 91-mile (146 km) tributary of the Nenana River in the U.S. state of Alaska. The Nenana is a tributary of the Tanana River, which is part of the Yukon River drainage in the central interior region of the state. Flowing northward from headwaters at the Cantwell Glacier in the Alaska Range, the Teklanika drains an area widely visited by tourists to Denali National Park and Preserve. The park's only road crosses the river at milepost 31 and a National Park campground is located on its eastern bank at milepost 29.
The 2002 Denali earthquake occurred at 22:12:41 UTC November 3 with an epicenter 66 km ESE of Denali National Park, Alaska, United States. This 7.9 Mw earthquake was the largest recorded in the United States in 37 years. The shock was the strongest ever recorded in the interior of Alaska. Due to the remote location, there were no fatalities and only one injury.
The Tangle Lakes are a 16-mile (26 km) long chain of lakes connected by streams in interior Alaska. They form the headwaters for the Delta River.
