My husband and I try to go on hikes to various places we can get to for day trips. About a year ago we also discovered geocaching. So naturally, as much as we can, we try to combine the two. For 4th of July this we we decided to revisit a park, but try a new trail.
We located the park using these sites: http://www.michigan.org/hiking/ and http://www.michigandnr.com/parksandtrails/Default.aspx?SearchType=trails and ended up at Pickney State Recreation area: http://www.michigandnr.com/parksandtrails/Details.aspx?type=SPRK&id=484 We did a great 6 mile hike that was not super easy, but it was well laid out. The trail we took was for both mountain bikers and hikers so on a holiday there was a lot of stepping aside for the mountain bikers, all very friendly.
We managed to find several “caches” while we were out there as well: http://www.michigandnr.com/parksandtrails/Details.aspx?type=SPRK&id=484
