This is no longer Blasus, it is now Pasta Boy which I do highly recommend. Very tasty pasta dishes and their coffee is excellent too.

Very interesting and remote, Fields can get high in grass so do keep that in mind to walk a bit further in and you will see the stones in the landscape.

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.

This pretty little chapel stands near the village of Mynachlog-ddu on the fringes of the Preseli Hills. From here, you could hike to Carn Menyn, Carn Siàn, Foel Drygarn and Foel Dyrch.
