DENVER (KDVR) — Get lost in the fall festivities with these corn mazes near Denver.

Most corn mazes open in late September, but you can start planning your trip now. Check out the corn mazes that are already open or are opening soon.

Anderson Farms

Starting on Sept. 20, Anderson Farms, located just outside of Boulder, is opening its corn maze for daytime fun and haunted happenings at night.

The farm is Colorado’s longest-running corn maze, opening back in 1999. It includes 8 miles of trails and allows you to choose one of three games.

Fritzler Farm Park

Fritzler Farm Park opened on Sept. 17 and is only open on the weekends.

The yearly designs of the maze in La Salle are unmatched. This year’s design is of Queen Reba’s face. The maze turns sinister at night with haunted features coming out once the sun sets.

Chatfield Farms

Chatfield Farms opened on Sept. 16 and runs all the way to Oct. 29 in Littleton. From a bird’s eye view, the corn maze’s theme is under the sea with fish, a sea turtle and a mermaid. The maze can be viewed from a 15-foot-tall bridge. There’s also a mini-corn maze for younger kids.

Mile High Farms

Just east of Denver in Bennett sit two corn mazes that span 11 acres. It starts on Sept. 30 and is only open on Saturdays and Sundays. There’s also a petting zoo, antique tractor hayride, pumpkin patch and barrel cart rides.

Cottonwood Farms

This cut-by-hand corn maze in Boulder is a narrow, personal experience. Because it’s not plowed by a tractor, it truly feels like you’re surrounded by corn. It’s perfect for a walk with the family as it’s only 2 acres. It opens for the season on Sept. 23.

Maize in the City

North of Denver is a corn maze, pumpkin patch and fall attraction all rolled into one. It’s open on Sept. 23. While this corn maze is about 20 acres long, it only takes about 40 minutes to complete.

Rock Creek Farm

Starting Oct. 1, Rock Creek Farm opens its 6-mile corn maze. There’s more than just corn in Broomfield. The farm is also known as one of the largest pumpkin patches in northern Colorado with over 8 acres of “U-Pick-Em” pumpkin fields.

These mazes shouldn’t take too long to complete, and most places have more than just corn. Look around the farms or find nearby fall activities to complete your autumn itinerary.
