Milltown Access is a hand-launch water access site on the South Fork Skagit River featuring a dirt boat ramp surfaced with crushed rock that is open for public use.

The site provides access to the Skagit Bay Estuary Unit and is popular for fishing, hunting, wildlife viewing, and paddling activities, with parking available and a private boat launch also located nearby.

Note that tides and river levels may restrict access, so visitors should carry and understand a tide book before visiting.
