As you cross over an ancient stone bridge into Merthyr Mawr, you feel as if you've entered another world. From stone cottages with beehive-shape thatched roofs to the Victorian-era Church of St. Teilo, with the pieces of its long-gone 5th-century predecessor lined up in its churchyard, it's an idyllic place to wander around. The picturesque ruin of Ogmore Castle is just off the B4524, but the most memorable way to reach it is via the walking path that starts in the car park at the very southern tip of the village. The mile-long route goes through a farm and a Shetland pony stable.
