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

lovely part of Cardiff, particularly on a sunny day. good spot for a stroll but very busy with families and people walking so not very suited for cycling

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.
