Discover Pinhook Bog

One of only two bogs in Indiana, Pinhook Bog offers a unique glimpse into the region’s geological past. The bog was formed approximately 10,000 years ago when the water from a melting glacial fragment formed a freshwater lake here. With no source of additional fresh water other than rainfall or melting snow, the lake stagnated for millenia, creating the incredible ecosystem we see today. The bog is home to 1/3 of Indiana’s rare or endangered plants, and its acidic water provides the perfect habitat for an amazing assortment of carnivorous plants and the remarkable sphagnum moss that flourishes here. The moss forms a thick bed on the surface of the bog where trees and other plants have taken root. Even the tallest trees here will shake when the water is disturbed, which is why Pinhook Bog is known as a “quaking bog.”

IMPORTANT: Pinhook Bog is only accessible via ranger-led tours on summer weekends. Upland Trail is available any time of the year.

Pinhook Bog & Upland Trail

A floating boardwalk traverses the landscape where you’ll see insect-eating plants and the most unexpected environments in the dunes. While the Upland Trail is open year-round, the bog is only accessible on select days with a ranger.
