[RWD version 1 ]
Yr Eifl is often one of the most visible summits from the Dublin or Wicklow mountains. It is a bit nearer and a bit lower, often under any cloud ceiling over Snowdonia to the north. With Yr Eifl North Peak it has a distinctive shape.
This walk was done as part of a surveying expedition, nevertheless it turned out to be a reasonably effective way of visiting both Yr Eifl and the surrounding peaks.
Park as shown where there is space for 2 or 3 cars and enter a field via a footpath gate. Extraordinarily there are two of these gates within 5 metres of each other. Navigation is not difficult and takes you past a largish outcrop (Caer Gribin) before reaching the col between Yr Eifl and the hillfort of Tre'r Ceiri. It would also be possible to go more directly to the top. The summit of Yr Eifl has great views and an odd, decorated trig pillar with the letters 4AH on some decorative ironwork. It turns out 4AH is part of the postcode. Although tracks to the west are shown on the 1:25k these did not see to go far so it is necessary to heather bash to the rough road below.
Yr Eifl North has been extensively quarried on the north east side and has some sort of rails for a rock carrier with steps beside it, handy for ascent. The top has great views along the coast and you may see some goats.
The route shown from Yr Eifl N to Tre'r Ceiri follows a faint animal path through high heather. This is nothing brillant but certainly better than what would otherwise be an unpleasant bash through high heather.
The hillfort of Tre'r Ceiri is an extraordinary experience. The route taken goes through an outer and then an inner wall both of which, even in ruins, are impressive structures with great detail such as fortified gates. Inside the inner area there are the foundations of over 100 buildings created during the Iron Age.
Descend the summit via the SW gate and a developed path to return to the start and then push on to Mynydd Carnguwch. The route shown went through a herd of cattle and some sheep and returned via more northerly outside the field beside a fence. Possibly the more northerly route is less intrusive though it is difficult because of traffic and high barbed wire fencing. The top is covered in a large cairn which appears to dominate much of the surrounding ground.
