I just have a
Trail fork ride log, but I usually park at
this lot. It's one of the few free lots and it's a nice central starting point for White Clay and Middle Run.
From here you can take Tri valley-snowgoose or lenape south.
And a few of my favorite sections: Snow Goose counter clockwise, double horseshoe counter, lenape south into lenape north coming off the lot is a great bit too, and tri-valley - lenape going south is fantastic.
If you work your way into white clay, I recommend David English (either direction), Whitely farms, and Wendel Cassel if you have the climb in ya (1 mile, 200ft descent, one way trail). Bryans field is okay but a bit of a climb for not a lot of payoff. The skills park is really fun too if you're into skinnies.
