Built in 1280, this castle has a fascinating life story. It is the second largest castle and grounds in UK, slightly smaller than Windsor castle. The water defenses are now home to plenty of birds and the grounds offer fantastic views of this stunning castle

Caerphilly Castle has had a £5m investment into conservation and repair of the structure - from late October '22 the scaffold and sheeting that protected the works will be removed. Caerphilly Castle is the biggest castle in Wales, and second biggest in the UK. Wales’s very own Leaning Tower, even wonkier than that of Pisa — courtesy of Civil War gunpowder is probably the castle’s best-loved feature.

Fantastic cycle lane surrounding a lot of the castle to get a good view from different angles.

Best way up on a bike - use the lower right hand route then go up the side of the mountain from in a SE direction. You can then choose the fun route down!

From this spot, you get a stunning view of Caerphilly Castle over the reflective water of the moat. With massive walls, towers, gatehouses, and water defences covering 30 acres (12 ha), Caerphilly is the mightiest castle in Wales and is second in size only to Windsor Castle in the whole of Britain. The castle was built from 1268 after the rise of the powerful Prince of Wales, Llywelyn ap Gruffudd, persuaded Marcher lord Gilbert de Clare that he needed a fortress building fast.

Good little cut through up over into Lisvane. Good climb up through the farm Passable on a road bike just turns a bit rough past the farm. Also watch out for the gate after the first decent.

This part of the trail is a little flatter than the sections before and after. It's also fairly smooth so makes for good running even when it's wet. Great views down into the valley!
