It services the Umpqua River, which flows into the Pacific Ocean.
The ramp is open to a variety of watercraft, including motorized and non-motorized boats, such as kayaks, canoes, and fishing boats. However, due to the strong currents and potentially hazardous conditions in the Umpqua River and Pacific Ocean, it is recommended that boaters exercise caution and be familiar with the conditions before launching their craft.
Overall, the Gardiner Ramp provides boaters with access to a scenic and popular waterway in Oregon, but it is important to take necessary safety precautions and be aware of any regulations or restrictions in place.
