Having likely got thoroughly lost on Day 3, Day 4's directions can briefly be summed up as "Mainly follow the A487", which will be a relief. The day starts (and mainly continues) by heading north, first to Haverfordwest then on to St David's. For those who don't know, St David's is the smallest city in the UK, population somewhere just shy of 2000 people, and I grew up in what many regard as the largest village in the UK (Lancing, population around 19,000), so, yeah, that's just a bit silly isn't it?
Ah, so if Lancing had a cathedral it too could be a city!
Onwards through Fishguard and Cardigan to Aberyswyth. I may even wear a cardigan in Cardigan just so I can say I have done so. Continuing northwards the place names get ever more unpronounceable and hoard "L"s as if there was once a shortage. Skirting the Snowdonia national park it will be onwards to Porthmadog, and then west to Pwllheli before heading onwards to Caernarfon. North once more to cross the Menai Strait on the Britannia Bridge at Llanfair Pwllgwyngyll, the place with the really long rail station signs and then skirting the edge of Anglesey on my "wrong way round" bit of my trip. I will actually have crossed over my route for Day 5 at Llanfair PG as I will be using the Menai Bridge to get back onto the mainland.
I would claim this is a future picture of me, but I've been to Llanfair PG before!
