January 24, 2024, Garreg Lwyd Summit

This is a very undervalued area of the western Brecon Beacons. The walking here is raw and wild, which is one of the reasons why it is also a quieter part of the park, so it will appeal to many. Here you also will find some of the best examples of Iron Age hillforts you can ever hope to see anywhere. Y Garn Goch and Y Gaer Fach are some of the most impressive hill forts in Wales. At 11.2 and 1.5 hectares, respectively, these are impressive structures and in their day provided considerable defensive structures to the native inhabitants. The large stone defensive ramparts, which are large rubble banks today, once stood 10m high and 5m thick. You can access both forts from a small car park at the base of the hill.
