Why Visit Garrison Dam

We often get asked, "is Garrison Dam worth visiting?" Our team unequivocally says yes. As one of the largest earthen dams in the world, the sheer scale of Garrison Dam North Dakota is a testament to human ingenuity, holding back the vast waters of Lake Sakakawea, the third-largest man-made reservoir in the United States. The dam area offers not just impressive views of Lake Sakakawea and the Missouri River, but also a gateway to abundant outdoor recreation. From its role in hydroelectric power generation to flood control and supporting diverse fish and wildlife populations, the dam is a vital part of North Dakota's landscape and economy.

Beyond the engineering marvel, visitors are drawn to the tranquility and recreational opportunities that Lake Sakakawea and the Missouri River provide. Whether you're a nature enthusiast, an angler, or simply seeking a peaceful escape with stunning vistas, the Garrison Dam area delivers.

It's an essential stop on any comprehensive North Dakota itinerary, offering a unique blend of history, engineering, and natural beauty.

Getting There & Parking

Understanding how to get to Garrison Dam is straightforward, as it's centrally located in North Dakota, near the town of Riverdale. Most visitors arrive by car, and the dam is easily accessible via well-maintained state highways. If you're coming from Bismarck, the state capital, it's roughly an hour's drive north on Highway 83, then west on Highway 200. Minot, another major city, is also about an hour's drive away.

For Garrison Dam parking, you'll find ample space at the various attractions. The Garrison Dam Project Office and Information Center, the Garrison Dam National Fish Hatchery, and the Power Plant tour entrance all have dedicated parking areas. If you're visiting Lake Sakakawea State Park, a daily vehicle entrance fee of $7 applies, or you can opt for an annual permit at $35 for a single vehicle or $61.25 for a family (two vehicles in the same household). These permits can be purchased online, through the call center (800-807-4723), or at any state park office. We recommend checking the specific parking instructions for any guided tours or events you plan to attend, especially for the Power Plant tours where visitors are asked to wait in their vehicles until directed to enter a secure gated area.
