Quite unusual, this church: its tower, its cruciform plan and - that I’ve not seen before - it’s oriented SW-NE. (And why not??) Inside, it’s peaceful calm, welcoming and with a cared-for atmosphere. Go visit if you’re passing.

A beautiful old mill with a lovely café, a lovely garden, and a small shop. You can also buy their own products there, such as wool blankets. A very nice stop while cycling or hiking.

The B4329 climbs up to Bwlch-gwynt ("Windy Gap"), forming the highest road pass in the Preseli Hills at an elevation of 404m. The climb from Brynberian is 4.3km in length with an average gradient of 6.4% and the steepest section around 11%. There are a lot of sheep freely crossing the road, or possibly over-taking you. Rain, mist and thick fog will frequently be experienced on this route.

The ruins of Aberfelin Corn Mill stand over Aberdraw Bay. They probably date from the fifteenth century. On the western gable was a wheel driven by a mill pond. The mill probably stopped operating in 1918. The place inspired Crwys (William Williams) to write the poem "Felin Trefin".

A short, sharp climb - leading up to the village of Mathry. The village itself was a site of a former Bronze-Age defensive hill fort, acting as a perfect high point to spot an approaching enemy. Today, it's a little more quiet and the locals don't worry about that sort of thing so much.
