M-37: Old Mission Peninsula End to End

Some road trips are measured in days. This one is eighteen miles and can be driven in half an hour, which is precisely the wrong way to do it. Old Mission Peninsula is a narrow sliver of land splitting Grand Traverse Bay into two arms, and M-37 runs up its spine from Traverse City to the lighthouse at the tip — with water visible on both sides for much of the way, vineyards and cherry orchards running down to the shore, and roughly ten wineries strung along the route. It is the most concentrated scenic drive in Michigan, and the shortest entry on any list of the state's great roads.

The Shape of the Peninsula

The peninsula is about eighteen miles long and narrow enough through much of its length that a driver can see water on both sides at once from the higher ground along the ridge — Grand Traverse Bay's east arm on one hand and west arm on the other. That geometry is the whole appeal, and it is genuinely unusual; very few roads anywhere offer sustained water views in both directions.

It is also the reason the agriculture works. The deep water surrounding the peninsula on three sides moderates temperature enough to delay spring budbreak past the worst frost risk and to hold warmth into autumn, which is what makes cool-climate viticulture viable this far north. The vineyards are not decorative; they exist because of the specific shape of the land the road runs along.

The Wineries

Old Mission Peninsula is one of two designated American Viticultural Areas around Traverse City, with roughly ten wineries along its nineteen-mile stretch — compact enough that the whole peninsula can be worked in a day without significant driving between stops. Riesling is the signature grape, alongside pinot gris, cabernet franc, and other varieties suited to a short cool season.

That compactness makes Old Mission the right choice for a first visit or a short one, particularly compared with the larger and more spread-out Leelanau Peninsula across the bay. Every tasting room welcomes walk-ins, though larger groups should call ahead. The transportation question deserves honest thought — shuttle and tour operators work the peninsula precisely because driving between tasting rooms all afternoon puts visitors in an obvious bind.

The 45th Parallel, Approximately

Markers and signs along M-37 celebrate the peninsula's position on the 45th parallel — the line of latitude halfway between the equator and the North Pole — and the association with the great cool-climate wine regions of Europe at the same latitude has been a fixture of local identity for generations.

There is a small and enjoyable complication. The 45th parallel does not actually pass through the commonly marked point; it lies a few hundred feet north of the peninsula's tip. The markers are approximate rather than precise, which does nothing to diminish the fact of the latitude but is worth knowing for anyone inclined to take a photograph and believe they are standing exactly on the line. They are standing very near it.

Mission Point Lighthouse

The road ends at Mission Point Lighthouse, built in 1870, standing at the tip where both arms of Grand Traverse Bay open out on either side. It is a modest, wooden, house-style light rather than a towering masonry structure, which suits the setting — this was never a coast that needed a monumental beacon, only a reliable one.

The lighthouse is open most days from May through October and weekends only in November, generally from ten in the morning until five in the afternoon, with self-guided tours available for a small fee that includes access to the tower. The surrounding park has beach, trails, and the shoreline at the very end of the peninsula, and it is the natural place to spend an hour after driving up. Checking current hours before making the trip is sensible, since the November schedule in particular is limited.

How to Drive It

The correct approach is to treat eighteen miles as a full day. Drive north on M-37 with stops at wineries, farm stands, and the overlooks along the ridge, spend time at the lighthouse and its park at the tip, and return south in the late afternoon when the light comes across the bay at a low angle. Cyclists should note that the peninsula is a popular ride, though the road is narrow and summer traffic is real.

Season shapes the experience more than on longer routes. Late summer and early autumn bring harvest and the best of the farm stands; spring is quieter with the vineyards bare; winter empties the peninsula entirely and a number of tasting rooms stay open through it, which makes for an unexpectedly good cold-weather afternoon. Whatever the season, this is the drive to recommend to someone with one afternoon in Traverse City and no idea what to do with it.
