Barry Island Pleasure Park is an amusement park on the coast of the Vale of Glamorgan, about 10 miles south west of Cardiff. It sits opposite the sandy beachfront and has fairground rides, games and stalls, and food outlets. Rides range from high-energy thrill rides to classic ones the whole family can share, and you pay for what you ride using tokens.

Coity Castle, also called Castell Coety, is a ruined Norman castle in Coity Higher, near the town of Bridgend. It was built by Sir Payn de Turberville, said to be one of the legendary Twelve Knights of Glamorgan. Today it is a Grade I listed building, and plenty of the medieval castle is still there to explore.

Tip: A small parking area sits beside the main gatehouse on the west side of the ruins, but it isn't clearly marked.

Castell Coch, Welsh for "red castle", is a 19th-century Gothic Revival castle above the village of Tongwynlais. Its conical-roofed towers rise out of the ancient beech woods of Fforest Fawr, and it has often been voted a favourite building in Wales. The architect William Burges rebuilt it for the third Marquess of Bute on the remains of a 13th-century fortress built by Gilbert de Clare.

Tip: The castle car park is free during site opening hours, and booking online saves 5% on tickets. Check Cadw's visitor notice for conservation work first.

Caerphilly Castle is the largest castle in Wales and the second-largest in the UK. Gilbert de Clare began it in 1268, and its concentric rings of walls, large twin-towered gatehouses and wide artificial lakes inspired Edward I's castles in North Wales. Historian Allen Brown called its water defences "the most elaborate water defences in all Britain".

Tredegar House is a Grade I listed Charles II-era mansion on the edge of Newport, run by the National Trust. For over five hundred years it was home to the Morgan family, later Lords Tredegar. It was rebuilt in red brick, a rare material in Wales at the time, and has been described as one of the outstanding houses of the Restoration period in Britain.

Tip: Dogs are welcome on a lead almost everywhere, but only assistance dogs are allowed in the mansion house. Keep them out of the lake.
