Sugar Loaf [Y Fal]

Sugar Loaf [Y Fal]

Sugar Loaf rises to 596m above Abergavenny in the Black Mountains, within Bannau Brycheiniog (Brecon Beacons) National Park. Its prominence is 411m, and the hill is a Marilyn, Dodd and Dewey. The summit is at SO272187.

Choosing an approach

• Mynydd Llanwenarth summit circuit: start and finish at the National Trust car park, SO268167. The National Park’s 5km circuit follows a grassy approach and western embankment to the summit, then descends south to rejoin the outward path at SO266179 and return to the car park. Allow 2–3 hours; the publisher grades it strenuous.
• Abergavenny town circuit: the Angel Hotel publishes an approximately 13.5km walk starting and finishing at the hotel, 15 Cross Street. It climbs through St Mary’s Vale via Pen-yr-Heol, reaches the summit, and descends towards Rholben before returning along the woodland edge and Chapel Road. Allow 5–6 hours for this strenuous outing. A different town starting point changes the distance.

Follow a current map and a complete itinerary. Offa’s Dyke Path follows the Hatterrall Ridge in this part of the Black Mountains; it does not run over Sugar Loaf.

Ground and summit

The slopes include grass, heather and bracken, with several intersecting paths. Rock and loose material make the upper climb and descent rougher. A trig pillar marks the summit area; the hill database notes nearby rocks slightly higher than the worn ground at its base.

The open top gives wide views over the Black Mountains and Usk Valley, with more distant horizons dependent on visibility. There is no season that guarantees clear views.

Geology and local history

The hill is formed from Devonian Old Red Sandstone rocks. Its lower slopes include the Senni Beds and Brownstones; resistant quartzitic sandstone of the Wern Watkin Formation caps the summit. These are sedimentary rocks, associated with ancient river systems.

The English name describes the hill’s sugarloaf-like outline. Below it, Parc Lodge preserves the landscape of a medieval deer park, including a surviving boundary bank. St Mary’s Vale and the Cibi Valley lie between the hill’s wooded southern spurs.

Getting there

Llanwenarth’s small car park is reached by narrow lanes. The road passes the vineyard and continues uphill to the walking start. The National Trust currently recommends Fairfield car park in Abergavenny, NP7 5SG, as an alternative, with a longer walk that needs planning.

Abergavenny has a railway station and bus services, but the upper trailhead is not directly served by public transport. Check current connections and allow for the onward walk or transfer. Use town facilities before setting out.

Safety

Steep, uneven ground and loose stones need care, especially when wet. Mist can make route-finding difficult among intersecting paths. Check the mountain forecast, carry suitable clothing and navigation equipment, and keep dogs on short leads around livestock.
