Mackinaw City to Port Huron Road Trip Guide

The Mackinac Bridge linking Michigan's Upper and Lower Peninsulas marks the start of this journey. At 4,600 feet, its main span is one of the longest suspension bridges in the Americas. From its base in Mackinaw City, you'll head southeast along the Lake Huron shoreline toward Port Huron.

This route covers roughly 280 miles and can be driven in about 5 hours without stops. But many hidden gems lie off US-23 and I-75. Consider an extra day to explore lighthouses, beaches, and small towns.

The Lake Huron shoreline offers sandy beaches, limestone bluffs, and dense forests. Richardson's Wildfowl Refuge near Oscoda is a birdwatcher's haven. The sunsets over Lake Huron are spectacular.

• Negwegon State Park: Quiet hiking trails.
• Tawas Point Lighthouse: Iconic photo spot.
• Local markets: Alpena Farmers Market on Saturdays.

The primary route is US-23 south from Mackinaw City to Standish, then I-75 south to Port Huron. US-23 hugs the coast for stunning views, while I-75 is faster. Fuel stations cluster in towns like Cheboygan, Alpena, and Tawas City; rural stretches require planning.

• Fuel economy: Expect around 25-30 mpg on this mostly flat route.
• Rest stops: Michigan rest areas on I-75 are well-maintained.
• Road quality: US-23 is generally good but can be narrow in sections.

Deer are common at dusk; use high beams when safe. Plan stops every 2 hours. Family-friendly attractions include the Great Lakes Maritime Museum in Alpena and the Huron Lightship Museum in Port Huron.

• Child suitability: Many beaches have gentle slopes.
• Pet-friendly: Dogs allowed on most state park beaches.
• Rest zones: Alpena's Starlite Beach has picnic tables.
