Apparently named after William, son of George IV, after a royal visit in 1821. This begs the question: What was it called before that? There must have been a native Irish name. Unfortunately Price provides no answer to this in PNCW. On the map of Wicklow contained in Wright's A Guide to the County of Wicklow (1827) this area is named Commons B.nulty, i.e. Commons of Ballynulty, which is a sub-division of the townland of Annacrivey. Since Prince William's Seat and Knocknagun they are only separated by a small saddle, it is possible that the name Knocknagun was applied to both peaks, but this is only conjecture.   Prince William's Seat is the 413th highest place in Ireland.

The information in Simon's comment about Prince William's visit to Ireland in 1821 begs the question: what was this mountain called before? Here is part of a map made in 1822, engraved by Sidney Hall. Can anybody read the place-name circled in red? It appears to be exactly where Prince William's Seat is now, but the name may refer to a townland rather than the peak. The names around it are: Glancullin (Glencullen), B.brew (Ballybrew), ?Black Anacree (?connected with Annacrivey), Knockbawn, Clon (Cloon) and Glanduff (presumably Glendoo, though expected further NW). Any ideas welcome! Linkback:

Climbed this last Sunday. Definitely not one for the solitude seekers. There were people on the summit when I arrived and when I returned from Knocknagun I had a minute to myself before more people arrived at the summit. I easily came upon 30 people on the climb incl. mountain bikers, a sport which looks insane but fun! The climb up through the forest was a different experience to most mountains in the range. Got back to the car park to see it now resembled a Formula 1 paddock! Linkback:

Took advantage of a free afternoon today to get up a hill in the scorching sunshine. I only met other seasonsed walkers and a chin strapped group of foreign students. From Glencree I took the Wicklow Way South. To my horror Coilte have been felling pretty much the entire mountain side making it look like a moonscape. Thankfully they left the Wicklow Way markers and red paint arrows to navigate through the lunar chaos. Getting above what was the woods the summit areas are pretty much the same. Took a quick side tour to Ravens Rock for the east coast views, too hazey to see the Cooleys or the Mournes. Went on to Prince Williams Seat and then Knocknagun. It was unusually easy underfoot thanks to the dry weather. Petty about the plastic bottles stashed in the grooves of the cairn, Coca Cola Bottlers should be made climb up and clear them away. Went back the same way. Good walk, great views and in fantastic weather! Linkback:

Has there been a change to the paths to the summit?
by dewsbury  14 Aug 2010
August 1st 2010. A group of us walked south-to-north along the Wicklow Way.

According to our map there should have been 2 paths to the summit of Williams Seat directly from the wicklow way. We skipped the first path (presumably this is the path which also goes to Ravens Rock). However we were unable to find the second path to the summit.

We carried on walking on the wicklow way and skipped the Williams Seat altogether.

Does anybody know if the paths to the summit have changed ?

My Daughter Andi and I walked on this Sunday. Quite a nice stoll thru the winding Wicklow way forest pass from the carpark at O18501680 starA. Until that is you come off the metalled road onto the forest proper. Following a horrid line of pink srpay paint on some of the rocks and stunmps, that interspersed the Wicklow Way marker posts.

Only the Joy of seeing the grin on Andis face lifted my spirits as she say the Trig point and her tired lges sprinted the last 150 meters from the way up over the purple sea of heather.

Good views, visability was great, Lunch fine while shelded from the wind on the east side of the trig points mound.

Andi found the largest ( and hairiest ) caterpiller i have ever seen - pic to follow ! Linkback:

Prince William Seat a grand place to be of a warm summers eve
by YoungJohn  3 Jun 2010
Set off yesterday from Dublin City for a hike in the Wicklow Mountains with three friends who were hill walking for the first time. We parked at the entrance to the Wicklow Way on the road out of Enniskerry heading for Glencree of a glorious summer evening. We set forth with intent of taking in some views and were at the foot of the Ravens Rock when one member of the party veered right preferring to let the remainder of the party head uphill. We ventured along the wicklow way taking in the beautiful views on offer of Dublin Bay, Bray and Greystones and admiring Great Sugar Loaf. We came across a rough track to the left just as the wicklow way seemed to go down hill. This track led us to a Cairn on the summit of Prince Williams Seat. I beleieve that this granite topped mountain has enticed two more souls into the hillwalking fraternity! The views of Kippure and the Dublin and Wicklow mountains were enthralling, Sugarloaf majestic. We headed back across the mountain top via a different track which led us back to the granite flagstones part of the wicklow way. We met up with the very relaxed and unlathered fourth member of our walking party who was sitting in the car with the aircon on! A lovely walk taking in two fine counties! Linkback:
