FC own large blocks of marginal land, often in areas suitable for mountain bike trails. Simplistically, better quality land is usually either built upon or used for houses/ buildings/ growing food. FC has a remit to provide recreational facilities (we fund the FC via taxation) but other, private landowners do not have to do this and I know of nobody who would do so. Further, the area required may be larger than a single parcel of land, raising lots of problems negotiating access etc.
However, there are a few places I know of in Wales that have met and overcome some of these difficulties to some extent.
Cwmrhaedr- community venture on FC land. Free access. You don’t even have to pay for car parking. 4 miles from nearest town/ railway station.
Trallwm- pay to park, private land, free trails. Nearest village about three miles, nearest station about four.
Garw valley trails- slap bang in middle of the village! No train. Free to park I think, free to use. Very compact area.
Penmachno?
Afan- easily accessible from Port Toilet on the cycle track.
Near Ammanford, the local council seem to be building tiny (just a few hundred metres length) skills trails in the local parks, as well as in the local ‘Country Paks’ like Llyn Llech Owain, Millennium Coastal Path and various others.
Bike Park Wales and Antur Stiniog both cost to use because they are private ventures. I’ve not been yet so can’t comment any more.
Fort William is hardly a huge distance from the trails at Nevis Range.
OP- I think you are trolling or unaware of what is being done in some places and also of why it is not being done in other places. Ordnance Survey maps show Right’s of Way and other paths and tracks. Inverness, with its very civilised Scottish land access laws will have lots to offer if you look. Go ask at the local bike shop.
‘I live in Harrogate. Nearest ‘proper’ trail centre is in Les Gets. ‘ Fantastic 🙂
