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 ❤️

Roath Park Lake has stunning vistas and tree-lined pathways. Lots of birds relax on the shores.

Wonderful cafe perched right over the edge of the lake - feels like being in a rowboat right on the lake! Enjoying a generous baked potato and chilli con carne marks a great end to a wonderful hike.
