Prince William’s Seat from Glencullen
Prince William’s Seat (555m) is said to be named either after the Fitzwillliam clan, owners of these uplands in the 16th and 17th Centuries, or in commemoration of the visit of the English monarch William III in the 18th Century. Regardless, its summit is classified as an Arderin (from the Irish Ard Eireann) — an Irish mountain over 500m. From Boranaraltry bridge, follow Yellow Man signposts, initially passing above the picturesque Glencullen valley, which is best experienced in the autumn. The trail later leads steeply up and out of a conifer forest to reach a junction with a Wicklow Mountains National Park signpost. Leave the waymarked path here and veer right to ascend a heathery and grassy slope southwest for the summit, marked by a trig pillar.
Park at the large car park along Ballybrack Road or lay-bys on Boranaraltry bridge
From Johnnie Fox’s Pub, head west at Glencullen crossroads along Ballybrack Road (R116). After about 1.6km, pass Boranaraltry Lane on the left and then a large car park on the right. Or, drive down Boranaraltry Lane and park on narrow lay-bys on Boranaraltry bridge where there are limited spaces. Moderate

Getting there: Level: Length/ Time: Pack:
Food and a pint of ‘the black stuff’ at the famous Johnnie Fox’s, which claims to be the highest pub in Ireland. Their hooley nights are a big tourist draw, but the place still retains its original charm.
