Spring Creek.
At Fishermans Paradise there is no wading allowed, and it is somewhat groomed, so people fish right from the bank. There are picnic tables there, and porta-potties. It's a very pleasant place.
There is also a PFBC access about half way between Fishermans Paradise and the Route 550 bridge where it's pretty easy to wade and fish.
There are several PFBC accesses in this stretch. But this one has the biggest parking area, a handicapped angler platform next to parking area, and a little shallow pond near the parking area.
You can park there and walk and fish on up around a big bend in the creek. Near the top of this stretch, you'll see a footbridge.
The PFBC owns that land, up past the footbridge a ways, to where you'll see a wall and a fence.
That stretch is probably about half a mile long and it's moderate in gradient, there's a footpath paralleling the stream, and the streambed is mostly gravel, not boulders, so the wading is pretty easy.
So I suggest trying those two places first.
There are other places you might see also as you drive along Spring Creek that are pretty easy to access and wade.
