Further to my request for information about an annual car park pass for Moel Famau, I’ve got the answer …thanks to Ron, who actually asked the question in the first instance!
For a fee £25 a year (no pro-rata available) you can get an annual car park pass that serves Moel Famau and Loggerheads car parks (and one other). Apparently they send you a plastic swipe card to use at the car park barriers and a paper disc (like a tax disc) with your car registration on. Replacement swipe cards are £5.
For further information contact the Forestry Commision on 0845 6040 845.
