Nice ascent from Crosskeys, but watch out for very overgrown pathways on the Machen side. Great views from the top!

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

The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

Caerphilly Mountain is located in the Vale of Glamorgan in Caerphilly and stands at 271 m above sea level. There are some magnificent panoramic views on offer here across Cardiff and Caerphilly, Feet, and on a sunny day, even over to Flat Home and Steep Home Islands, a pair of welsh islands lying in the Bristol Channel.

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.
