no leash is fine, pretty much everyone does it at waway, even on a crowded day you will at best run into 4 groups of hikers max and about the same for bikes as long as you stay away from the beach.
Is the loop starting up hof and ending on iron mountain? if so, you may want to reverse it, iron mountain is a good warm up loop but is not all that interesting of a trail, if you did it as a cool down that works as well.
Should you split the ride into two groups you might want to include mojo and porcupine for the more advanced group(hard to tell if you are doing cherry to nature jims or something else here)
The ride is starting at William Hoeferlin and going South, and ending back at William Hoeferlin.
Yeah, the Iron Mountain around to William Hoeferlin was a cool down finish.
I don't know mojo and porcupine to add them into the ride. Here was my plan:
Starting at the main office parking lot take the William Hoeferlin trail South.
This brings you to Double Pond Tr.
Make a right and go a few hundred feet to Plymouth Lane Tr. on your left, look for the fender. Plymouth Lane takes you to Banker Tr.
Make a right here and ride to Cherry Ridge Tr.
Make a right again and ride to the first trail on your right, Red Dot Tr.
This takes you to the North end of Double Pond Tr.
Make a left, through the campground and up the road / hill past the furnace to the lake and dam. This is Wingdam Tr.,
Go left here and ride past the other dam, through the laurels to Sitting Bear Tr. on your right.
This will take you to South End Tr. on your right. South End will take you to Pumphouse Tr.
Make a right and ride to the end, you’ll see the West end gate parking area.
Make a right down the road, as you start downhill on the paved part look for Iron Mountain Tr. on your left.
Ride this and it comes to the beginning of William Hoeferlin Tr. as it veers right, if you went straight just exits the park by houses.
Coming up the double track section of William Hoeferlin it makes a sharp left onto a wide single track. The road you were on goes straight to the main paved road.
This single track of the W H Tr. brings you back to the parking lot. 15.25 miles.
