Calling buckinghamshire land rovers

So been told by a few people about a short greenlane in Holtspur near Beaconsfield. Anyone in the area know of it. meant to be a nice easy lane about a mile or so long.
just completly unsure of where to turn off for entrance. apparently there is another one on the ashridge estate which you have to buzz yourself onto the land which i wouldnt mind also looking at if people know anything about this.

ta

There is an ORPA on the OS map from the sewage works to Forty Green called Riding Lane on my map that looks about a mile long. As its an ORPA I don't know the access rights, so a call to the ROW officer for Bucks might be in order. I don't think I've been down it as I usually mark it up on the map when I do.

I had a recce round Ashridge a few years ago on my bike. Barring some short sections, the few BOATs there were had been tarmacked or at least ballasted. I can't recall having to buzz open a gate, so I might not of been everywhere.

Hope that helps

yeah the one on ashridge i heard it was controlled letting you in and you had to be buzzed on and there were reg plate recognition cameras that took a photo of your plate so they could keep a idea of who was going on the byway.
ill keep looking and digging
