Old Yellowstone Trail Park County
The boat ramp is approximately 12 feet wide, which is enough to accommodate most small and medium-sized watercraft. However, it may not be suitable for larger boats or those with trailers wider than 12 feet.
The Yellowstone River is a popular destination for recreational boating, fishing, and other water-based activities in Montana. It is the longest undammed river in the lower 48 states and offers a range of opportunities for anglers, paddlers, and boaters.
According to the Montana FWP, the Yellowstone River is open to all types of watercraft, including motorized boats, canoes, kayaks, rafts, and paddleboards. However, there may be restrictions on the size and horsepower of motorized boats, as well as rules regarding fishing and other activities on the river.
It is important to note that boaters should always check the latest regulations and restrictions before launching their craft at Old Yellowstone Trail Park County or any other boat ramp in Montana. This will help ensure a safe and enjoyable experience on the water.

Boating safety & etiquette
- Check the conditions before you launch
- Use the streamflow numbers, weather, and wind forecast on this page. High-cfs whitewater requires whitewater-specific craft and skill.
- Wear your life jacket
- Statistically the single biggest survival factor in a boating incident. State law often requires one per passenger.
- File a float plan
- Tell someone on shore your put-in, take-out, and expected return time. Especially for multi-day or remote trips.
- Yield at the ramp
- Prep gear in the parking lot, not on the ramp. Launch and clear quickly so others can use the lane.
- Clean, drain, dry
- Inspect, clean, drain and dry your boat between waters to prevent the spread of aquatic invasive species.

About Old Yellowstone Trail Park County
Can I launch a motorboat here?
Most Snoflo-tracked launches support motorboats; check the operator for any horsepower restrictions, paddle-only zones, or seasonal closures.
How fresh is the streamflow data?
USGS streamgauges report continuously (every 15 minutes); the table on this page pulls the latest reading at page load.
Is there a fee?
Many federal and state boat launches charge a day-use fee. Check the operator's site before driving out.
What boat is right for these conditions?
Use the nearby streamflow numbers and river-run panel on this page to gauge current conditions. Wider, slower water is friendly for casual paddling and powerboats; high-cfs whitewater requires whitewater-specific craft and skill.
Can I get alerts when conditions change?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this launch, set a threshold (discharge, wind), and you'll get a push the moment it crosses.
