Explore diving in Illinois

Mermet Springs and Haigh Quarry are two of the most popular dives in Illinois. Both are flooded quarries, now utilized for water recreation and diving. Their long removed pasts only revealed by the relics beneath.

In Mermet Springs, divers have the opportunity to dive in a Boeing 727. At Haigh Quarry, head to Artifact Park-an area created to teach divers how to engage in underwater archaeology. Whilst diving the springs and quarries there are plenty of bluegill and bass, as well as fantastically large channel catfish.

Cold, blue Lake Michigan offers a surprising amount of shipwrecks to discover. Be sure to make a trip to the Tacoma, a tugboat with a stellar propeller.
