Swim to the Moon is an extraordinary open-water swimming adventure through the picturesque Hiland Chain of Lakes near Hell, Michigan.

Choose your distance — .5 Mile, 1.2 Mile, 2.4 Mile, 5K, 10K or 15K — and have the time of your life swimming through Southeast Michigan’s most sublime waterways, all the while showing support for a very worthy cause: North Star Reach, a camp for children with life-threatening, serious, and chronic medical conditions.

What swimmers are saying:

"The course was truly epic. I had never swum 5k before but really enjoyed the point-to-point concept! There was so much to look at while swimming, it made it feel so much more enjoyable than the standard out-and-back swim on a large lake or ocean that I'm used to."

"A day we will reminisce about. It was great, from the tiki lanterns early this a.m. to the aid stations to the lovely finish, you thought of all of the details. You guys really organized a wonderful event (and we've been to quite a few open water events from Chicago to Chesapeake)!"

"From the packet pickup to the start in the dark with glow stick tails, and especially for the few of us that were recognized for doing the Sunday 10K complete with medals and towels!"
