π Technical Details
Upland walking on grass, moorland and stony paths with some steep, sustained climbs and descents; no scrambling or significant exposure. Sure-footedness needed on rough, boggy ground.
Waymarked across farmland but unmarked on open hill and moorland; the National Park Authority states map-and-compass competence is essential and signage is sporadic. Some trackless sections. Sits at the upper end of Hard, approaching Expert in poor visibility.
Mix of firm farmland tracks and rough, faint upland paths; boggy and tussocky moorland on the Black Mountain and Mynydd Du sections pushes some days approaching A Bit Of A Slog territory.

π Best Season
Best in late spring to early autumn for daylight and conditions; the high moorland is exposed and serious in winter with short days. Walkable year-round by the experienced.
π Logistics & Budget
Pub meals and B&Bs add up quickly; baggage-transfer packages raise the flashpacker figure. Dirtbag assumes discreet wild camping and supermarket/shop resupply.
Eastern start at Abergavenny is on the Cardiff-Hereford mainline (frequent trains, station parking).
Western end at Llangadog has a request stop on the sparse Heart of Wales line with the nearest significant hub is Swansea. Best done by train as a point-to-point.
B&Bs, guesthouses, pubs-with-rooms, bunkhouses/hostels and campsites along or near the route. Wild camping is not a legal right in Wales. It should be done very discreetly on high ground (pitch late, leave early) or with landowner permission.
πΆ Vibe
A quiet, rugged through-route stringing together the Black Mountains, the central Beacons and the Black Mountain (Mynydd Du), with castles, standing stones, glacial lakes (Llyn y Fan) and Welsh-speaking villages. Genuine solitude on most days, punctuated by the busy Pen y Fan honeypot.
π Safety & Inclusion
Very low crime. The principal hazards are weather, exposure and navigation on unmarked moorland, plus limited and patchy phone signal. Standard UK mountain-safety precautions apply.
