A huge garden with flowerbeds as far as the eye can see. The roses are currently in season and the variety and quality is outstanding. Thank you to all those who maintain this flower Paradise ❤️

Nice ascent from Crosskeys, but watch out for very overgrown pathways on the Machen side. Great views from the top!

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.
