Indiana Dunes consists of 2,182 acres of primitive, beautiful, historic and unique Hoosier landscape. It lies at the north end of State Road 49 in Porter County, and includes more than three miles of beautiful beach along Lake Michigan
This is a lovely trail through the woods, I am not sure what the pictures refer to as you are in the woods the whole time and there are markers with the trail name. The trails are primarily sand and if you go on the extensions, mostly dirt, and all are well maintained. Apart from that you are hiking on sand, which is a new twist for me, and perhaps the length, I'm not sure why this is considered a hard trail as there really are no significant hills. It was very nice though.
No dunes or ridges on this trail. Not sure what the other reviewers were referring to. Mostly flat. Lots of trees, but not terribly scenic. Not sure why it's rated hard. Moderate is more like it. Mostly loose sandy trail slows down the pace a bit, but otherwise a good hike.
Did Trail 9 yesterday. It's labeled as moderate, but I'm heavy and new to exercise. It was definitely challenging, especially in ridge "blowout" areas with deeper loose sand. It was worth it! I felt good about myself when I finished, and the view was BEAUTIFUL!
