Mad River Boat Ramp at Mad River Beach County Park provides operational access to the Mad River estuary, located just a couple miles upstream from where the river meets the Pacific.

The ramp accommodates both motorized boats and paddling craft (canoes and kayaks), with a large parking area and restroom facilities available; the river maintains adequate depth for paddling even at low tide due to strong tidal influence.

Day-use fee is $5, and the location is popular for fishing and wildlife viewing, particularly for birding along the muddy banks and riparian areas.
