The Essential Guide to Indiana Dunes National Park

"This 4.7-mile-long loop was named after Dr. Henry Chandler Cowles, whose early 1900s research here helped establish ecology as a scientific field. The path passes wetlands and savannas before reaching the lake. The final sandy section is strenuous, but the shoreline is worth the effort." - Iona Brannon Iona Brannon Iona Brannon is a journalist with a love for food and travel.
