1. Search a destination
Enter a city, lake, river, harbor or launch name. The finder can locate nearby source-backed launches even when your destination name is not part of the facility name.
Michigan public boating access
Michigan boat launches, on one map
Open the map and browse. Or search one place — a city, lake, river, harbor or launch name — and the map focuses there. Great Lakes and inland public launches are in the same tool.
Michigan DNR is the primary source. DNR launches shown here are source-reported Open. If DNR is still checking amenity data, the detail card says that in plain language.

Green = Michigan DNR currently lists the launch Open. Violet = separately verified municipal launch. Blue = your selected launch. Local NWS weather appears in the selected launch card; it does not change statewide pin color. Map tiles © OpenStreetMap contributors / CARTO.
Find the water first
Michigan boat launches by water
The statewide finder includes Great Lakes, connecting rivers and inland waters. Search any city, lake, river, harbor or launch above, or start with one of these existing guides for high-use Michigan waters.

Use the official source better
How to use Michigan DNR boat launch data
Looking for a boat launch near you or the Michigan DNR boat launch map? This finder keeps Michigan DNR boating-access records as the primary source, then adds destination search, routing, source-state checks and local National Weather Service planning weather. It does not invent a ramp, amenity or coordinate when the source is incomplete.
2. Compare the useful facts
Check ramp type, trailer parking, source-reported status and other facility details when the source publishes them. Missing facts stay labeled as missing.
3. Verify the launch
Open the selected launch card for directions and its source context. DNR review flags are kept separate from open/closed status so a data-review state is not mistaken for a closure.
4. Check the water separately
An open ramp does not mean the lake is safe or comfortable. Use the selected launch weather and the Great Lakes buoy dashboard for wind, waves and water temperature.
Near-me privacy: precise device location is requested only after you tap “Use my location.” The nearest-launch calculation happens in your browser; your coordinates are not stored or sent to this site. You can always search a city, lake, river or harbor instead.
Primary records come from the Michigan DNR boating program. Carefully documented municipal launches are used only to fill specific public-data gaps; guessed or fuzzy-matched launch pins are not shown.
How the launch data and weather are handled
Michigan DNR boating-access records create the statewide inventory. The tool keeps a stable DNR source ID, published coordinate, source-reported launch status, facility-condition field and data-review state as separate concepts. A DNR “review in progress” flag means some record details are still being checked; it does not mean the launch itself is closed or unsafe. Records marked Review Needed, reference-only entries and records without usable source coordinates are withheld. Carefully documented municipal launches can fill a public-data gap only when the operator and launch location are independently supported.
- The map never creates a launch from fuzzy matching or a guessed coordinate.
- DNR condition values are preserved and shown only when the source actually publishes one; blank values are not turned into a rating.
- Missing parking, ramp, fee or hours fields remain “Not listed.”
- Driving distance is used when a destination has been searched and routing is available; otherwise distance is labeled as straight-line.
- Local weather comes from the National Weather Service for the selected launch coordinate. It is planning context, not a statement that the ramp, lake or river is safe.
