Old Mission Boat Ramp provides river access to the Coeur d'Alene River via a single launch ramp with ample parking, located next to I-90 at Old Mission State Park.

Upstream paddling may encounter shallow waters and rapids below the I-90 bridge, while downstream paddling requires a shuttle due to strong current; note that shoreline erosion limits landing options and most beaches are on private property.

The launch is conveniently situated near the historic Old Mission State Park and the Chain Lakes system extending toward Harrison, Idaho.
