About Griffith, IN

Nestled in northwest Indiana, Griffith stands out as a charming town with a rich past and a vibrant present. Founded in 1904, it earned the nickname "The town that came to the tracks" thanks to its boom as a major railroad interchange. Five railroads once crisscrossed the town, with over 180 trains rumbling through daily at its peak.

Today, the echoes of that bustling era linger in the Griffith Historical Park and Railroad Museum, a delightful stop for history buffs. Every Labor Day weekend, the town celebrates its heritage with the lively Rock 'N' Rail Street Festival, featuring music, food, and family fun.

But Griffith is far from stuck in the past. Its downtown buzzes with modern energy, boasting eclectic shops, barbershops, restaurants, and even a record store! Families flock to the bowling alley and pool hall, while art enthusiasts wander through the "A Park Full of Art" show.

For nature lovers, Griffith offers a haven in the 576-acre Hoosier Prairie Nature Preserve. Here, amidst marshes, savannas, and wet prairies, you can spot diverse wildlife and reconnect with the tranquility of nature.

Whether you're seeking a glimpse into railroad history, a taste of small-town charm, or a vibrant community for your family, Griffith has something to offer. Its warm atmosphere, diverse attractions, and convenient location near Chicago make it a hidden gem in northwest Indiana.
