The 3 Cardiff Castles

Starting from Cardiff Castle, a simple walk up the Taff Trail, passing through Glamorganshire Canal Nature Reserve, stopping at Castle Coch and then continuing up to Caerphilly Castle, finishing in the Court House for drinks and food if you like.

Train back to Cardiff Central.

11.5 miles / 18km - a gentle 400m elevation gain aside from the one bastard of a hill at Castell Coch.
