St. Helens Marina Boat Ramp is a privately owned two-lane ramp offering $5 access to the Columbia River at river mile 86, with a large parking lot across the street and restroom facilities available.

The site is convenient for quick loading and unloading but can get busy during fishing season; boaters should use caution navigating the narrow, congested channel.

Adjacent Grey Cliffs Waterfront Park provides picnic areas and beach access, while the marina itself offers fuel, supplies, and additional amenities.
