Head out towards Chewton you should do OK,
Actually you will probably come in through Chewton from the freeway, so just have a poke around there. Have a look up Golden Point Rd. From there you could go down to Fryerstown for a bit of a side trip. You can get Graptolites in the Shale in one of the cuttings out near the old Wattle Gully mine, not sure of exactly where.
