February 8, 2026, Cardiff Bay - Bute Park Loop

Relaxing routes following Cardiff Bay Trail, and then into Bute Park, crossing at Blackweir Bridge. Perfect Sunday afternoon ❤️

This route is almost exclusively on dedicated cycle paths away from cars. Such a relaxing ride!

September 29, 2025, Bay Park Ride

This route visits the sea, the bay, Pontcanna fields, trees, rivers and bridges. It's always an absolute pleasure cycling this route

A wonderful sea and park tour just as all the baby birds are taking their first steps on land. Lots of hissing geese but lots of cute fluffy ones as well. Cute for now 😄🐥😈
