William O'Brien State Park-Riverway Campground

16821 O’Brien Trail N, Marine On St Croix, MN 55047

Date Visited: June 2018

Site: #40-E, BACK-IN, ELECTRIC ONLY, 30 AMP (DUMP STATION AND WATER FILL AT SAVANNA CAMPGROUND)

We paid: $35 PER NIGHT (PLUS THE DAILY STATE PARK FEE)

Review: This campground is right on the St. Croix River and has lots of brush and trees. Sites are a bit small and the roads are narrow, but we did okay. It was very hot and muggy here (late June).

There is a walking path around the campground and along the river, and there is a biking path that extends north and south of the campground.

We would probably stay here again when in the St. Paul area, though cooler weather would make it much more pleasant.
