April 3, 2025, The Garth Summit

The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

At 1,056 feet (322 m) tall, Mynydd Meio is a fairly modest hill rising immediately west of Caerphilly. From the summit and much of its rounded bulk, you can enjoy wonderful views of the surrounding hills, valleys and across to Caerphilly Castle.

We walked miles. Up to the waterfall on Gillies trail, followed the path up onto the rocky and then to the trig point on Twyn Brynbychan, above the cynnon valleys. Enjoyed a breather on top, before trekking around the back forestry where you can see Aberfan and Merthyr Vale and headed over to the bronze age sight before descending down to Cwmaman and back to the car.
