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

The weir spans the River Taff, which flows directly through the heart of South Wales. It's a nice place to stop and refuel with picnic benches and a peaceful atmosphere.
