Glacier Trails Conference

The Glacier Trails Conference was formed in preparation for the 2025-26 school year, and consists of seven high schools. Three members (Kettle Moraine Lutheran, Kewaskum and Plymouth) left the defunct East Central Conference to help form the new conference. The other four schools to enter the league came from the North Shore Conference (Port Washington, West Bend East and West Bend West) and the Fox River Classic Conference (Sheboygan South).^[1] The Glacier Trails Conference was named after the glaciers that shaped the Kettle Moraine, a geological region that coincides with the geographic footprint of the conference.^[2][3] Conference membership is set to expand to eight schools per the WIAA Board of Control's ruling in March 2026 that Grafton will be joining the Glacier Trails from the North Shore Conference for the 2027-28 school year.^[4]

Football competition is set to begin with the 2026-2027 WIAA realignment cycle, and all members with the exception of Sheboygan South will be participating. The addition of North Shore Conference members Grafton (currently affiliated with the Woodland Conference for football) and Nicolet will bring the conference's football membership to eight schools.^[5][6]
