The Ice Age National Scenic Trail (IAT) is one of the most unique long-distance trails in the United States. Stretching for more than 1,200 miles across Wisconsin, this trail follows the path left by glaciers during the last Ice Age. It highlights geological formations like moraines, kettles, eskers, and glacial lakes, making it both a hiking adventure and a journey through Earth’s ancient history. Ice Age National Scenic Trail .
The trail passes through prairies, forests, rolling farmlands, and small towns, offering a mix of rugged wilderness and cultural landscapes. It is part of the U.S. National Scenic Trails system, which also includes famous routes like the Appalachian Trail and the Pacific Crest Trail.
Hikers come from around the world to experience its variety, whether for short day hikes, section hikes, or the entire thru-hike. What makes the Ice Age Trail famous is not only its length but its rare combination of geological history, natural beauty, and accessible segments for all levels of hikers.
Best Time to Visit
The Ice Age Trail can be enjoyed year-round, but conditions vary with Wisconsin’s seasons:
- Spring (April to June): Mild weather, blooming wildflowers, and flowing streams. Trails may be muddy from melting snow.
- Summer (July to August): Warm temperatures and long daylight hours. However, mosquitoes and ticks are common.
- Fall (September to October): The most popular time, with cool air and spectacular autumn foliage.
- Winter (November to March): Snowshoeing and cross-country skiing are possible in many sections, but cold weather and snow make thru-hikes challenging.
For long-distance hikers, late spring or early fall is usually the best balance of comfort and trail conditions.
How to Reach
Since the Ice Age Trail crosses much of Wisconsin, access depends on the section you plan to hike.
- By Air:
- Milwaukee Mitchell International Airport (MKE) and Madison Dane County Airport (MSN) are the closest hubs.
- Green Bay Austin Straubel Airport (GRB) is convenient for northern segments.
- By Train/Bus:
- Amtrak connects Milwaukee, Madison, and Chicago, from where buses and local transport reach nearby trail towns.
- By Road:
- Many trailheads are accessible by car. Parking lots are available near state parks, forests, and trail junctions.
Because the trail spans an entire state, it’s common for hikers to plan section hikes starting at easily accessible towns.
Entry Fees and Permits
- General Access: The trail itself is free to enter and hike.
- State Parks and Forests: Some sections pass through Wisconsin State Parks or campgrounds, which may charge entry or camping fees (approx. $5–$15, subject to change).

Unlike other U.S. long trails, the Ice Age Trail does not require a single thru-hiking permit. Ice Age National Scenic Trail .
Food Availability and Meal Options
One of the advantages of hiking the Ice Age Trail is its proximity to small towns and communities:
