Nearby communities include Beulah to the east, Elberta directly across the Betsie River to the south, Honor to the southeast, and Traverse City approximately 50 miles to the northeast along US-31.

Frankfort has the feel of a classic northern Michigan harbor town, where maritime traditions, local shops, and a tight-knit community define daily life. The local economy is anchored by tourism, seasonal hospitality businesses, commercial fishing heritage, and small retail along Main Street and the waterfront. Year-round residents enjoy a quiet, outdoor-oriented lifestyle with access to beaches, trails, and Betsie Bay, while summer months bring a lively influx of visitors drawn to the lakefront.
Transportation
Frankfort is primarily accessible via US Highway 31, which runs along Michigan's western Lower Peninsula and connects the city to Traverse City to the north and Manistee to the south. Michigan Highway 115 also provides an inland route connecting to communities further east. The nearest commercial airport is Cherry Capital Airport (TVC) in Traverse City, located roughly 50 miles northeast of Frankfort.
History
Frankfort was established in the mid-19th century as a harbor and lumber town, benefiting from its natural deep-water port on Lake Michigan at the mouth of the Betsie River. The city became a significant hub for the lumber industry during Michigan's great logging era, and later developed a strong commercial fishing trade. The historic Frankfort North Breakwater Light, which still stands at the harbor entrance, has guided mariners safely into port since the late 1800s and remains one of the most photographed landmarks in Benzie County.
Did you know?
One surprising fact about Frankfort is that it sits at the terminus of the Ann Arbor Railroad's car ferry route across Lake Michigan, a service that once transported entire railroad freight cars across the Great Lakes — a remarkable piece of transportation history. The natural alignment of the Betsie River valley also makes the Frankfort area one of the best spots in Michigan's Lower Peninsula to observe the Northern Lights on clear nights.
