🌲 North Dakota’s Deepest River Gorge — 30 Miles of Trails Through the State’s Largest Forest — A dramatic river gorge recreation area with 30+ miles of multi-use trails for mountain biking, horseback riding, and OHVs, North Dakota’s largest continuous forest, Pembina River kayaking, and Icelandic heritage — Cavalier County, North Dakota
Pembina Gorge State Recreation Area protects one of North Dakota’s most dramatic landscapes — a steep, forested river valley carved by the Pembina River that shelters the largest continuous, undisturbed forest in the entire state. The gorge sits at a remarkable ecological crossroads where boreal forest, eastern deciduous forest, and central grassland all converge, creating biodiversity found nowhere else in North Dakota.
With 30+ miles of multi-use trails open to mountain bikers, equestrians, and off-highway vehicles, this is North Dakota’s adventure-sport destination. The nearby town of Walhalla preserves deep Icelandic heritage — settlers arrived in the 1870s and built what was the largest Icelandic settlement in the United States.

Frequently Asked Questions
Is this really North Dakota’s largest forest?
Yes. The Pembina Gorge protects the largest continuous, undisturbed forest in the state — a dramatic exception to the prairie landscape that dominates North Dakota.
Can I kayak the Pembina River?
Best in spring/early summer when water levels are highest. It’s often called ND’s only “whitewater” river, though it’s relatively tame. Seasonal rentals available in Walhalla.
What’s the Icelandic connection?
Walhalla and the surrounding area were settled by Icelandic immigrants in the 1870s — the largest Icelandic settlement in the US at the time. The Vikur Lutheran Church is the oldest Icelandic church in North America.
Keep exploring: The closest neighbors are Icelandic State Park (within about an hour’s drive) and Turtle River State Park (elsewhere in the state).
