Green Lake is known for its fishing and recreational tourist community during the summer months.

Area activities include camping, biking, fishing, hiking, golfing, swimming, and boating.

The small town has a number of shops and restaurants that serve Green Lake fish.

Since that humble beginning in 1975, the business has grown from the cheese haus, ice cream parlor, and antiques shop, to include a gallery loft of fine art and furniture.

Nearby is the Green Lake Conference Center, which was founded by the American Baptist Churches USA in 1943.

Also near the conference center are the Golf Courses of Lawsonia, built on the former estate of Victor F. Lawson, the owner and publisher of the Chicago Daily News.

The Dartford Cemetery, located in Green Lake, has been a focus of reported paranormal activity in the area.

Some visitors to the cemetery claim to have been tripped by ghosts or "pushed off" the mausoleum when sitting or standing on it, even seeing apparitions of child victims who died of a disease (possibly polio) or a Native American chief.

These sightings and experiences have been featured in the episode "Legend Trippers" of the Discovery Channel's A Haunting series.
