If you want even more specifics, I think at around the 4:20 mark he is probably right here. I could be wrong though. There are a couple of spots in the preserve that look just like that.
I love it back there, it's very pretty. And fishing is allowed. Watch for bald eagles, they may compete with you for the fish! Have fun
Use the link @stiltzkin posted above and just switch to another map that shows the roads, such as this. You can see there's an upaved road off of Route 532 East of Chatsworth.
