Griffin Bay Access is a barge landing on the east side of San Juan Island that serves as an emergency backup facility for the San Juan ferry terminal and provides access for vehicles and freight delivery to outer islands.

The facility features timber stringers and pilings but is currently unusable in its present state; vault toilets are available at the end of Jackson Beach Road nearby.

Access is controlled by a locked gate, and the site is primarily used for commercial barge operations rather than recreational access.
