Purchased in 1930, this preserve is one of the most serene and pleasant areas in the County. The preserve is bisected by Grove Creek, which has high limestone bluffs on its north and south sides. The campsites are interspersed in a majestic stand of bur oaks. Located just off Highway 20, Seward Bluffs is two miles south of Pecatonica and the Winnebago County Fairgrounds, and is also an excellent overnight area for traveling campers. Host on duty in campground May-October. There are 60 sites (11-50 amp & 49-30 amp), dump station, horseshoe pits, & playground.
