Trenton Bluff Prairie State Natural Area

This 110-acre site consists of two units of dry prairie situated on steep 300-foot Mississippi River sandstone bluffs
capped by massive limestone cliffs. These are some of the best prairies remaining in the region. The western unit has two prairie openings with a wooded draw running between them. The eastern unit is steeper with an open cliff and oak woods. Bobolinks, Grasshopper and Clay-colored Sparrows are found here along with hognose snakes, olive hairstreak and Reakert’s blue butterflies. Bald Eagles and Turkey Vultures glide by on early morning and late afternoon thermal winds and give one a great opportunity to see these birds at bluff-top levels and admire their aerial skills.

Directions: From the intersection of Hwy 35 and Cty VV north of Hager City, go west 1.5 miles on Hwy 35 to a small pull-off in a wooded draw north of the road. For the eastern unit, travel north .4 miles on Cty VV and park along the road. Walk due west through the woods and upslope to the prairie.
