Alaska has always been a land of wild beauty, where towering mountains, massive glaciers, and untamed wildlife create an adventure unlike anywhere else. In 2025, the state’s national parks are drawing record numbers of visitors, even as staffing cuts reduce ranger-led programs. Despite these challenges, Alaska remains a paradise for those seeking close encounters with bears, moose, caribou, and whales. From the viral excitement of Fat Bear Week to the timeless appeal of glacier hikes, this guide explores the top 8 national parks in Alaska where unforgettable adventures await.
Why Alaska’s National Parks Are Unique
Alaska is home to more than half of all U.S. national park land, making it a true wilderness frontier. These parks protect ecosystems where Alaska wildlife thrives from grizzly bears and bald eagles to humpback whales and massive caribou herds.
Visitors come not only for the animals but also for the landscapes: fjords carved by ice, sand dunes in the Arctic, and the tallest peak in North America. Seasonal highlights add to the magic summer brings endless daylight for hiking in Alaska, autumn showcases Fat Bear Week in Katmai, and winter offers aurora-lit nights.
In 2025, however, travelers should be aware of changes. Staffing shortages mean fewer guided hikes and educational programs, especially in Denali and Glacier Bay. At the same time, cruise tourism is booming, with nearly 60% of visitors arriving by ship. This combination makes planning ahead more important than ever.
What’s New in 2025: Staffing Cuts and Visitor Experience
Recent reports confirm that Alaska’s national parks are facing significant staffing shortages in 2025. Denali National Park has already reduced ranger-led youth programs, and the Mendenhall Glacier Visitor Center in Juneau is operating with limited hours. While this means fewer guided hikes and educational talks, it also highlights the importance of self-guided exploration and private wildlife tours. Visitors should plan ahead, book early, and prepare for a more independent adventure experience.
