The park's terrain was formed by the retreat of the Des Moines Lobe glacier approximately 10,000 years ago.
Mountain Lake is a spring-fed kettle lake, formed when a buried block of glacial ice melted, leaving a depression.
The park protects rare native prairie remnants that have never been tilled by agriculture.
Visitors can find a mix of three distinct biomes: tallgrass prairie, deciduous forest, and oak savanna.
The park features an accessible fishing pier located on the shore of Mountain Lake.
Glacial Lakes State Park features a unique landscape shaped by the last glacial retreat, creating a transition zone between tallgrass prairie and hardwood forests. The park covers over 1,700 acres and includes the spring-fed Mountain Lake, which is noted for its high water clarity. Visitors utilize a network of trails for hiking, horseback riding, and snowshoeing throughout the diverse topography. The park provides primitive and electric campsites, along with camper cabins for overnight stays. Wildlife viewing opportunities include waterfowl, deer, and various grassland bird species. The area is situated on the terminal moraine of the Des Moines Lobe glacier, resulting in rolling hills and kettle lakes. Facilities include a swimming beach, a boat launch, and picnic areas equipped with tables and grills. The landscape is managed to restore native prairie remnants through controlled burns and invasive species removal.
The scenic overlook near the trailhead of the glacial ridge path offers a panoramic view of the rolling prairie and Mountain Lake.
Bring binoculars to identify grassland birds in the prairie sections, especially during early morning hours.
Check the Minnesota DNR website for prescribed burn notices before arrival, as some trails may be temporarily restricted.
Wear sturdy, closed-toe hiking boots to navigate the uneven terrain of the moraine hills.
Do not attempt to swim outside of the designated beach area, as some lake edges are soft or obstructed by submerged debris.
Park grounds are open year-round, though some seasonal amenities like water access or specific campsites may be winterized.
Practice Leave No Trace principles; keep dogs on a 6-foot leash at all times; do not remove any plants or historical artifacts.
