Waking up once again at 5am due to the early light, I spent a while on Criccieth beach before enjoying a superb second breakfast, with proper tea cup and everything, at the Tir A Mor café as soon as it opened at 08.30. They’d put a few tables out on the square (“we didn’t ask, but nobody’s said anything”) and it was rather fun sitting under a rain umbrella eating breakfast with the town going about its business around me, although they all probably wondered why my boots kept squelching water all over the pavement. They'd been full since the previous morning and I'd enjoyed the usual delicious pleasure of putting them on again this morning.
Sadly it was time to head back north, using NCN 8 to Caernarfon and Bangor. It’s not the most interesting of cycle trails, but I perked up once I realised that at the half way point were the Nantlle Vale quarries I’d foregone the previous day! Bad luck folks, there’s more

. The quarries used to be served by a fascinating railway line linking them all together. It had the very unusual gauge of 3 feet and was horse-worked for its whole life. It was built in 1825 – the same year as the famous Stockton & Darlington railway – and incredibly lasted in the same form until 1963. The most incredible part of all was that horses were used until the day it closed by which time it was actually part of British Railways. Goodness knows whether HQ in London even knew they had a horse-drawn railway. You can imagine the baffled looks upon receiving a claim for expenses…. “oats? horse-shoes? What on earth are they
doing up there?”.
As with the quarries in the previous couple of days, one could have spent hours and hours nosing around. I followed the railway track through many pits including Cefn Coed, Talysarn, Cilgwyn, Dorothea, Twll Ballast, Twll Mawr, and Penybryn; all sorts of fascinating structures are hidden in the undergrowth, including Talysarn Hall, a quietly crumbling mansion partly overrun by slate waste tips – many of them looking like standard BBB bivvy spots in different circumstances!
I then remembered it was a good idea to have come back this way because I’d printed a few historical photos and brought them with me to see what has changed. One of them was a picture of the end of the railway where it started to climb an incline into Pen Yr Orsedd quarry only a few yards from where I changed route the previous day. It took rather more than half an hour to find the exact spot, even though it turned out I was more or less standing on it in the first place. For a bit of fun I tried to take a “then and now” photo…. plus a restoration project for someone…
Turning back down the valley, the final port of call would be Dorothea quarry, recent scene of many a diving difficulty sadly. It too has its own unique monument being criminally left to moulder away – a Cornish beam engine, one of the last three ever built, in 1906. It pumped water from over 500’ deep in the quarry until 1951. Apparently grants have even been made available for restoration but work has foundered due to access problems. Everything is still intact although the pump rod has been severed. What a superb addition a restoration would make to Wales’s industrial heritage. Sigh.
Again I’d spent far longer than I intended soaking up the atmosphere, I was still only half way back to Bangor, so it was a quick ride up to Caernarfon, a snap of the castle for form’s sake, then the final leg to Bangor. I have to say that this section of NCN 8 is possibly the nastiest cycle trail I’ve ever been on. It runs next to the main A487 at one point then down into the town. The road was a howling monster, and the route through the town traversed areas that, how can we put it delicately, were not in the peak of urban health. My mood was not enhanced when a tattooed harridan in a BMW pulled straight out in front of me at a roundabout. My fingers-on-brakes and full expectation of this at every roundabout saved me, but of course she thought it was my fault she hadn’t stopped at the give-way lines and jumped out to harangue me. My one Welsh swear word came in handy, but legging it proved the sensible option. And that was Bangor’s fond farewell to me as I went to the station and boarded the 18.05 to Crewe and Milton Keynes.
If you've stuck this out to the bitter end I compliment you. You are now an Official Slate Nerd like me
