About the count: 101 sellers are mapped with a verified street address and pinned above; 1 more are participating but haven't confirmed an exact address yet, so we don't pin them rather than place them wrong. Smaller home sales also line the corridor for the full 177 miles without registering — drive day-of and watch for hand-painted signs.
For one weekend each August, the shoreline roads around Michigan's Thumb turn into a long ribbon of yard sales, barn sales, and small-town antique stops. The M-29/M-25 Yard Sale Trail follows the water — up M-29 along the St. Clair River from New Baltimore, through Port Huron where M-25 begins, then north along the Lake Huron shore around the tip of the Thumb and down the Saginaw Bay side toward Bay City. It is well over a hundred miles of coast if you drive the whole thing, strung across the little harbor and farm towns that ring the Blue Water and Thumb country.
This is old resort-and-farm territory, and the goods reflect it: lake-cottage and cabin finds, nautical and fishing gear, cast iron and hand tools out of Thumb farmsteads, vintage glassware and kitchenware, primitives, and the everyday Michigan Americana that comes out of a shoreline garage cleanout. Port Sanilac, Lexington, and Port Austin anchor the classic Lake Huron stretch, while the St. Clair River towns of Marine City and St. Clair bookend the south end.
The trail is pulled together each year by the Great Lakes Event Network, whose official trail magazine publishes the participating household sales, multi-family groups, and antique-shop stops town by town along the route. Individual property owners, harbor communities, and shoreline shops all take part, so density varies from town to town — the map above pins every stop we can confirm, from New Baltimore in the south up around the Thumb. Most sellers keep roughly 9 a.m. to 5 p.m. each day. Pick a stretch of coast, or run the whole shoreline; most shoppers base around Port Huron or one of the Thumb harbor towns and work a segment at a time.
This route runs through these anchor towns. Drive any segment, or the whole route — most folks pick a stretch and work their way through it.

Friday, August 6 through Sunday, August 8, 2027. Most sellers keep roughly 9 a.m. to 5 p.m. each day, rain or shine; harbor and farm towns along the route set their own hours, so the earliest stands open Friday morning.
Along Michigan's Thumb shoreline — up M-29 from New Baltimore along the St. Clair River through Marine City and St. Clair to Port Huron, then north on M-25 up the Lake Huron coast through Lexington, Port Sanilac, Harbor Beach, and Port Austin at the tip, and down the Saginaw Bay side through Caseville toward Bay City. The map above pins each anchor town.
From south to north the corridor runs through New Baltimore, Marine City, St. Clair, Port Huron, Lexington, Port Sanilac, Harbor Beach, Port Austin, Caseville, and Bay City — ten anchor towns around the Thumb. Most shoppers pick a stretch of coast rather than driving all of it in one day.
Yes — the Great Lakes Event Network publishes an official trail magazine each year listing the participating household sales, multi-family groups, and antique-shop stops town by town, with several community maps along the route. Participation is still up to individual property owners and shoreline communities, so density varies year to year. MapMySales pulls every confirmed stop into one map so you can see the whole route and plan how to drive it.
It runs every year on the first full weekend of August. The 2028 dates will follow the same pattern; we'll update this page when they're confirmed.
