Plymouth Rock Access is a well-maintained boat ramp located off Cold Water Creek Road and 303rd Avenue, offering ample parking and a short ramp to the water—making it an ideal put-in point for canoe and kayak trips on the Upper Iowa River.

This access marks the beginning of popular paddling routes, including the scenic 4. 3-mile stretch to Cattle Creek Road Bridge, and provides easy access to explore the river's clear waters and limestone bluffs.

The site is situated near the historic Plymouth Rock landmark, a former sawmill location from 1853.
