The boardwalk begins at a paved parking area just off the highway and stretches through muskeg to the rapids of Blind Slough. At the end of the trail, a small day-use shelter sits just above the high tide level of the slough. There is a barrier-free outhouse in the corner of the parking area.

The Blind River Rapids trailhead is 15 miles south of Petersburg on the Mitkof Highway.

A popular place to watch and fish for king and silver salmon during their migrations.
