Icelandic State Park

Icelandic State Park sits near the Pembina Escarpment in northeastern North Dakota, a region settled by Icelandic immigrants in the late 19th century and still celebrating that heritage. The park centers on Renwick Dam Lake, a quiet reservoir on the Tongue River, surrounded by the wooded hills of the escarpment — a landscape remarkably different from the flat Red River Valley just to the east.

The park offers swimming, boating, fishing, camping and hiking in a family-friendly wooded lakeside setting, alongside the Pioneer Heritage Center — a museum complex interpreting the Icelandic and other immigrant heritage of the region. With its quiet lake, wooded setting and cultural depth, Icelandic State Park is a beloved four-season retreat and a treasured icon of northeastern North Dakota.

Summer (June through August) is the prime season, with warm lake temperatures, swimming, boating and camping at their best, and the park at its busiest. Spring and fall bring quieter shores, good fishing and the beauty of the wooded escarpment in new green or autumn color. Winter offers a quieter park and ice fishing. Summer for the lake and swimming, and fall for the wooded color, are the highlights — come in summer for the full lake experience or the shoulder seasons for solitude and fishing.

The wooded hills and lake of Icelandic State Park harbor white-tailed deer, wild turkeys, beavers, and a diverse birdlife — waterfowl on the lake, forest songbirds in the woods, and raptors overhead — while the lake holds walleye, northern pike and perch. The wooded escarpment and the lake support a variety of wildlife richer than the surrounding open prairie. Icelandic offers pleasant wildlife watching and birding, with waterfowl, forest birds and the deer among the highlights, in the wooded lakeside park.

Renwick Dam Lake is a family lake — wear life jackets and follow boating rules (watch for other boats and windy conditions that can raise waves). The water is cold early in the season; supervise children at the beach and swim in the designated area. The woods have ticks and mosquitoes (use repellent and check for ticks). In winter, ice conditions vary (check before ice fishing). Respect the lake, the boat traffic, the cold water, the ticks and insects, and (in winter) ice conditions.

Icelandic State Park offers swimming and a beach on Renwick Dam Lake, boating and kayaking, fishing (walleye, pike and perch), camping (electric and primitive sites, modern camper cabins), hiking on wooded trails through the escarpment, picnicking, and visiting the Pioneer Heritage Center. A disc golf course and playground add variety. Swimming and boating on the lake, hiking the wooded trails and exploring the heritage center are the signature draws. The combination of a quiet lake, wooded park and family-friendly facilities makes Icelandic one of the most popular parks in northeastern North Dakota.

Northeastern North Dakota was settled in the 1870s–1890s by Icelandic immigrants who were drawn to the region’s fertile prairie and named the surrounding communities (Mountain, Akra, Hallson) for places in Iceland. The Pioneer Heritage Center at the park preserves and interprets this Icelandic and broader immigrant heritage — with historic buildings, artifacts and programs celebrating the settlers who built the region. The park itself was established to protect the wooded escarpment lake and share it with the public. Icelandic State Park is a treasured natural and cultural icon of northeastern North Dakota.

Icelandic State Park lies near the Pembina Escarpment, a prominent ridge in northeastern North Dakota marking an ancient shoreline of glacial Lake Agassiz — the vast Ice Age lake that covered the Red River Valley. The escarpment’s wooded, hilly terrain (of glacial deposits and the old lake bed’s edge) rises above the flat Red River Valley to the east. Renwick Dam Lake was created by impounding the Tongue River. The glacial lake’s ancient shoreline, the escarpment ridge and the impounded river created the park’s lake and wooded hill setting.

Icelandic State Park protects a stretch of the Pembina Escarpment woodland — oak, ash, elm and other trees on the hilly glacial terrain — and the Renwick Dam Lake reservoir, forming a woodland-and-lake ecosystem on the edge of the Red River Valley. The wooded hills and the lake are ecologically significant, providing habitat for wildlife scarce in the surrounding farmland. Protecting the lake’s water quality, the woodland and the riparian habitat sustains both the ecology and the recreational beauty of Icelandic State Park.

Icelandic State Park holds a special place among the icons of northeastern North Dakota — a family recreation park on a quiet wooded lake, celebrating the Icelandic immigrant heritage of the surrounding communities through the Pioneer Heritage Center. The region’s Icelandic settlers are honored in the park’s name and programs, a proud heritage unique in North Dakota. The park embodies both the natural beauty of the Pembina Escarpment and the cultural richness of northeastern North Dakota’s immigrant heritage.

Icelandic State Park is in Cavalier County in northeastern North Dakota, near the town of Cavalier (about 8 miles south), reached via U.S. 81 and State Highway 5. A state-park entry fee applies. The park has modern camping (electric sites and camper cabins), a swimming beach, boat ramp, hiking trails, a disc golf course, playground, and the Pioneer Heritage Center (with its own hours and fees). Check ND Parks & Recreation for the entry fee, camping reservations, Heritage Center hours and conditions before visiting.

North Dakota Parks & Recreation protects Icelandic State Park and Renwick Dam Lake. Visitors help by cleaning, draining and drying watercraft to prevent aquatic invasive species, keeping the lake and shore clean (pack out all trash), staying on trails to protect the woodland, respecting wildlife, and following all park rules. The lake’s water quality, the woodland and the heritage buildings are sensitive and valued. Protecting them sustains both the ecology and the recreational and cultural value of Icelandic State Park.

A state-park entry fee applies; camp only in designated sites (reservations recommended in summer). Clean, drain and dry watercraft to prevent aquatic invasive species. Follow North Dakota boating laws and life-jacket requirements; observe speed limits. Fishing requires a North Dakota license. Pets must be leashed. Drones are restricted. Fires are permitted only in designated areas. Pack out all trash. Check ND Parks & Recreation for the fee, reservations, Pioneer Heritage Center hours and rules before visiting.

The town of Cavalier (the Pembina County seat), the Pembina Gorge State Recreation Area and its forested canyon (about 40 miles southwest), the International Peace Garden on the Manitoba border, the city of Pembina on the Red River, and the northeastern North Dakota prairie lie near the park. The Pembina Escarpment and the Red River Valley define the region. Icelandic State Park anchors the recreation and heritage of northeastern North Dakota, easily combined with the Pembina Gorge, Cavalier, and the International Peace Garden.

Base at Icelandic State Park for a summer lakeside retreat — swim and boat on Renwick Dam Lake, fish for walleye and pike, hike the wooded escarpment trails and visit the Pioneer Heritage Center to learn about the Icelandic immigrant heritage of the region (check Heritage Center hours in advance). Come in fall for the wooded color of the escarpment and quieter camping. Clean your boat to protect the lake, bring insect repellent and check for ticks in the woods, and combine your visit with the spectacular Pembina Gorge to the southwest.
