No high horses and wont be camping up there either....
Zokes .. If only I could explain, it is an interesting situation.. I dont really know it's origin ... possibly military, there were a lot of American Regiments in North Wales during WWII and needed lots of training, many mountain cart tracks such as the one over the three peaks at the horseshoe pass near Llangollen originated from these US Army Jeep tracks, they never became rights of way other than the road passing from World's End to Minera which the yanks tarmaced after the war as thanks for been welcomed by the locals.
I note that my Garmin Oregon GPS mapping shows many tracks including ones in Caersws forest which are private forest roads used for the downhill racing that the farmer made himself, The OS maps are generally quite good for defining both rights of way and public roads on maps in this area they have only ever recorded it as a physical feature and never assigned any public right of way to it.
I would doubt anyone has seen a recreational 4x4 up there as it's a shoot on sight management strategy for any of the SNP militia who are often seen loitering about in their white landrovers as motorbikes are a regular problem on Conwy Mountain and on Drum, as one poster points out these guys are a whole lot greater grade of unreasonable than the NT wardens who are mostly seasonal and gap year students.
There are a number of well used rides in this area not all are open legally to cyclists and are either footpaths or nothing. . having had meetings with the SNP and County Council to talk about trying to regularise access to some of them, meetings generally seem to suggest they consider unauthorised use by mtbs is predominently local riders who don't benefit by aggravating the landowners, numbers remain minimal and so do not pose a threat so it is easier to turn a blind eye.. if use levels increases or rider behaviour turns for the worse then the situation would be reviewed. I figure the more online route hawkers and web sites featuring the ride as some kind of off road Alton Towers that day of reckoning will come all the sooner.
Before the usual dawn chorus of those braying to suggest we all ignore it and ride anyway, they also might want to note that current plans to build more mtb trails in Snowdonia with 4 or 5 local enterprise groups partly in competition to secure a lot of EU funding to do it, it will be important to have the local councils and national park supporting the plans as they both have the capacity to veto and withhold the needed match funding. If they think opening up more trails just increases the number of visiting mountain bikers who show little respect and increasing acts of trespass on private land in protected landscapes, it is harder to make the case to get the support from the councillors and committees who will have an eye on keeping their local residents as happy as much as eyeing any earnings from incoming visitors
