Afon Soch

The Afon Soch's estuary is probably one of the most pictured on the peninsula, with fantastic views across the bay to Snowdon, providing a stunning backdrop.

The river starts at Rhos-ddû, between Dinas and Llaniestyn in the centre of the peninsula and flows south through a fairly steep valley to Sarn Meyllteyrn. It then passes the eastern slopes of Mynydd Rhiw and flows through Botwnnog towards Porth Neigwl (Hell's Mouth).

At one point the river is only about half a mile from the wide bay of Porth Neigwl, but then turns back in the other direction, past Llanengan and through a sharp glacial gorge to Abersoch on the calmer east coast. The picturesque harbour in the village centre only fills up on high tides, but when it does it can be quite deep and sluice gates have been installed to prevent it running further up the valley in these circumstances.
