October 22, 2025, Elidir Fawr Summit

Poor Elidir Fawr! It has been bashed about and big lumps knocked out of it at Dinorwic Quarry, it has had a power station built inside it, and has a reservoir for that reservoir almost at the very top. Fortunately when you climb it from Nant Peris you will only see the reservoir, the rest of the damage is ot of sight.

On the longest day of the year, sunlight flows into the passageway of this Neolithic burial grounds. Bryn Celli Ddu Burial Chamber is one of Anglesey’s most famous prehistoric landmarks, Bryn Celli Ddu (the ‘Mound in the Dark Grove’ in English) is actually two sites in one. In the early Neolithic (New Stone Age) period, a henge (bank and ditch) enclosing a circle of stones was built here, to be replaced later by a chambered tomb beneath a mound measuring up to 85ft/26m in diameter. Inside, a long, narrow passage leads to an octagonal chamber 8 feet/2.4m across, where artefacts such as human bones, arrowheads, and carved stones have been found.
