We went last summer and had a BLAST! I had an 8 year old and a 1 year old at the time.
We went to Miners Beach. It was chilly, the lake usually is, but not so much that we didn't swim. We also went to the log slide. There was a short "hike" on a trail to get to it. There was a HUGE log hauler that we saw on the way. The "slide" goes down to the water. Since there was NO WAY I was going to go down with a 1 year old, my son and hubby went. They had on their swim suits, so they went swimming at the bottom and cooled off. Take water along if you go there. You can google it for the exact location.
We also just went driving one day and pulled off at one of the side of the road places. It turned out to be called the "shallows" . It was SO shallow WAY far out. And it was super warm since it was so shallow. My son thought it was neat to go that far out in Lake Superior! There were a few holes, but it was fine.
My hubby and son took one of the sunken ship tours, too. It was too long for the baby and I , but they loved it. That was out of Mackinaw City , I think though.
We went to a small zoo up there and a bear farm. Can't remember the names (I think the zoo began with a G).
It was such a laid back vacation. We all loved it! Have fun!!!! And eat some pasties!!! (If You go to Muldoon's they have great ones to buy and take home! 1246 W State Highway M28, Munising, MI 49862 )
