The Conwy estuary path is free — last train east 21:40, Sunday is buses

Park once if you have to, then ignore the castle kiosk. The estuary path is the North’s secret that is not a secret: free, windy, and better than a timed slot. Hour out, hour back. Pontio is Bangor if you wanted a billed night after; the last train east is still the constraint.

Sunday: Chester–Llandudno Junction is buses. A55 westbound is overnight works. If you only read one thing, read that, then go anyway.
