The Heybridge Boat Ramp sits on the Blythe River near the town of Heybridge, a few kilometres east of Burnie in Tasmania's northwest, where the river meets Bass Strait. The site is accessible from the Bass Highway (Route 1) at Heybridge.

The Blythe River at this location is tannin-stained and flows through an estuary that can offer productive fishing, particularly during the spring whitebait run when juvenile galaxiids attract sea-run and resident brown trout.

A weir is located approximately three kilometres upstream from the river mouth.
