ABOUT DENALI RAFTING ADVENTURES
Navigating the Nenana River Since 1974
Established in 1974, Denali Raft Adventures is the original rafting company on Alaska’s Nenana River, just outside Denali National Park. As a family-owned and operated business, we specialize in providing unforgettable Alaskan rafting experiences, combining thrilling whitewater action with stunning natural landscapes.
Our Story
Our journey began when Jim Raisis moved from California to the Denali region in the 1970s. Jim, originally a raft guide and mechanic, partnered with Valerie, a raft guide, in 1989. Falling in love with the area’s beauty, they made Denali their permanent home, raising their son, Demetrios, who now continues their legacy as the current Operations Manager.

The Nenana River and Denali Region
The Nenana River, a glacial river, forms the eastern boundary of Denali National Park and is one of Alaska’s most popular rafting destinations. It offers a variety of rapids suitable for different skill levels, making it ideal for both novices and experienced rafters. The river’s unique path includes a U-turn through the Alaska Range, creating a wide, low corridor that has favored the construction of both the Alaska Railroad and the Parks Highway.
Denali National Park, encompassing over six million acres, is home to North America’s tallest peak, Denali. Established in 1917, the park offers diverse ecosystems, from forested lowlands to glacial highlands, providing a habitat for a wide array of wildlife. It’s a haven for mountaineers, hikers, and adventurers seeking to experience Alaska’s raw, untouched wilderness.
Environmental Stewardship
At Denali Raft Adventures, we are deeply committed to preserving the natural beauty of Denali and the Nenana River.
But our commitment goes beyond maintaining the beauty of the area—we aim to inspire that same sense of care and respect for the outdoors in everyone who joins us. Through our actions, our guides share their love for Denali and the river, showing guests how to enjoy these pristine landscapes responsibly. It’s not just about experiencing the beauty of Denali; it’s about fostering a lasting appreciation for nature and encouraging guests to protect it long after they leave.
We believe that by sharing our passion for the land, we can inspire others to become stewards of the environment, embracing the same sense of responsibility and care. Every rafting trip we guide is an opportunity to cultivate a deeper connection with nature, reminding us all that protecting these wild places is a shared responsibility, and it’s through these shared experiences that we can make a real impact.
