Thunder Bay River Kayaking Guide

The Thunder Bay River is northeast Michigan's great unknown — a substantial river system running from the Atlanta area eastward to Alpena and Lake Huron, with well over 80 miles of potential river corridor. It flows through a landscape of state forest, farmland, and small towns, offering the kind of uncrowded, exploratory paddling that is getting harder to find. For kayakers willing to do their homework, it promises long quiet reaches, good fishing, and a genuine sense of discovery.

The honest framing comes first: detailed public documentation for paddling the Thunder Bay River is sparse. No reliable segment-by-segment mileages are published, and the river's multiple impoundments and dams mean it cannot be treated as one continuous float — every trip must be planned within a known free-flowing reach, with dams identified and portaged. This guide does not invent distances or routes; it gives you the confirmed access point, the character of the river, and the planning approach the river demands.

What is documented is encouraging. The Thunder Bay River State Forest Campground, about 9 miles southwest of Alpena, offers a small launch with water access at each campsite — a rustic, affordable base for exploring the nearby river. The surrounding state forest land means long stretches of undeveloped shoreline, and the river's cool, clear water holds the fish that make this corner of Michigan a year-round angling destination. Come prepared, paddle conservatively, and you will have a river largely to yourself.

Paddling the Thunder Bay River

Thunder Bay River State Forest Campground Area

The state forest campground is the best-documented paddling base on the river, with a small launch and water access at each campsite. From here, explore the nearby free-flowing reach as an out-and-back, keeping your turnaround well short of any upstream or downstream impoundment. The rustic setting — state forest on the banks, few other boaters — is the river's great reward.

Planning Longer Reaches

Local sources reference more than 80 miles of river between the Atlanta area and Alpena, but without published segment mileages or confirmed portage routes, longer through-trips are an expedition for experienced paddlers only. If you attempt one, identify every dam and impoundment on current maps, confirm each portage on the ground before committing, and travel with a group. For most paddlers, day trips from known access points are the right call.

Hazards & Portages

Dams and impoundments are the critical factor: the river system has several, and each must be portaged — never approach one without knowing exactly where the carry is. Beyond the dams, expect the standard north-woods hazards: strainers, sweepers, beaver dams, and cold water early and late in the season. The river's remoteness means self-sufficiency is essential; cell coverage is spotty and help is far away.

Access & Parking

Thunder Bay River State Forest Campground (map centered near 45.07631, -83.79007 — confirm the campground location with the Michigan DNR before traveling) offers rustic campsites with water access and a small launch. Parking is informal. Because public access documentation is limited, verify your chosen access point with the DNR or local sources before making the drive, and have a backup plan in the Alpena area.
