This bridge gives great views of the marina, and forms part of the Cardiff Bay loop

The Barrage connects Penarth to the Cardiff peninsula. It offers stunning views across the sea to one side, and the freshwater bay on the other. One of the highlights of the Cardiff Bay tour

Quite steep in places, wouldn’t call it an easy walk.

Nice easy flat ride. Can be busy with walkers and other cyclists, particularly on weekends. Early mornings are the best, with so much birdsong and wildlife. Take a moment to enjoy the view of the Weir, which usually has a row of gulls fishing on it.

This tree carving is masterful and the size of an adult. Its remote location imbues an aura of mysticism.
