Inga's is an unofficial river access along Salmon River Road at Duncan Creek, between the 5 and 6-mile markers. Look for the very large pullout.
This access is used primarily by boaters wishing to lap the action-packed top mile of the Butler Run or, sometimes, by boaters coming down from the Nordheimer Run who wish to add another mile of prime whitewater to their day (but why not go all the way down the Butler Run?). Inga's is named for the woman who lived at a riverfront home that is no longer here.
