The Three Eagle Trail is a 12.7 mile non-motorized hiking/biking/ski trail that connects the towns of Three Lakes and Eagle River, Wisconsin.

The trail is largely off-road, pedestrian pathways surfaced with crushed, compacted limestone, an ideal surface for biking, walking and running. Separating two sections by about 1.5 miles are asphalt surfaced town roads, Sundstein Road and Section 9 Road.

The plan for the future is to connect the two sections with another off-road route. A more detailed description of the two existing trail sections is available at http://www.3eagletrail.com/background.html

In the winter, 5 miles of the trail is groomed for traditional straight-track and Nordic skate cross country skiing.

Free parking is available at both trail heads in Eagle River and Three Lakes. Free parking is also available at the mid-route trail heads at Sundstein Road, and at the trailhead for the cross country ski trail off of Highway 45.

The trail is supported by the Three Eagle Trail Foundation, whose goal is to develop, construct and maintain a safe, family friendly, biking and walking transportation route connecting the Town of Three Lakes and the City of Eagle River, and to support future connections of the trail to a larger network of non-motorized trails across Vilas (much existing) and Oneida (still only in concept) counties.
