Madison County, Iowa is world-famous for its covered bridges and charming small towns. While most people stop by to visit the man-made wonders in Winterset and the surrounding area, Iowa historians and nature lovers flock to Pammel Park. This was one of the first state parks around, and it’s home to the oldest trees in Iowa.

Pammel Park was dedicated in 1928 as one of the very first state parks in Iowa. It's famous for its sprawling woodland beauty and a limestone "backbone" that's a hiking destination in Madison County.

Pammel Park is known for their towering white oaks that date back more than 400 years! When the oldest tree in the state was blown down by a storm, scientists were able to determine it was at least 440 years old.
