The last time I rode the Indian Valley Trail was 8 years ago. The upper section in Donegal and Saltlick townships was indeed a great ride. I tried to do the lower 5 mile section in Springfield but didn't have much luck. I found the trail where it crossed Mill Run Rd but lost it on the west side of the Mill Run Reservoir.
I've heard that section has since been improved going east through the gorge, ending at an old RR bridge where Indian Valley Creek joins the Yough. I also heard there are plans to eventually connect it to the GAP. Might try it again in the spring.
aww man,you missed the best section!
ive been going there for years before it was ever a bike trail

we used to walk down to the end of the old railroad bed and camp out underneath the trestle where indian creek meets the yough.
sorry in advance for the book i write hahaha
when you came down the gravel road by camp christian and turned to the right,
you needed to cross the bridge with the gate closing it off,
theres room to go around.
(gate is there because the guy that monitors the dam on the lake lives back there,
hes super cool,we talk to him often)
then as you go back the path,it splits,
straight follows the lake edge down to the breast of the damn and dudes house,
and LEFT takes you through a beautiful cut with rock cliffs on both sides,
before dumping you out into a very remote area with a killer smallmouth stream that empties into the yough river,
no people/houses/civilization/anything down in there lol
back in the 1800s there used to be a town down there called Hampton,there are still old foundations to be found,
my great grandmother was born there.
ive heard they have been planning to make a foot bridge across the yough at the end of the indian creek trail,to join it to the GAP trail,
i wish they would hurry up and do it already lol
