Have you completed the Waterways Adventure Labs yet? If not, now is the time to do so!

Seven Adventure Labs that each feature 10 locations were released in 2022 to help people explore Michigan's waterways and maritime heritage. Pathtags and a geocoin can be earned by completing and recording code words from the Adventure Lab stages.

This summer, participate in a separate challenge by completing or finding caches close to Waterways Adventure Lab stages. Complete the results form and submit it no later than October 15, 2026 (11:59 PM). Project-GC will be used to determine the winner of the challenge. NO ENTRY FORM IS REQUIRED.

Players are expected to understand and play by the Common Contest Rules as well as the MiGO Code of Fair Play.

Anyone can play, but only MiGO members can win. For more information on joining MiGO, click here.
