4-Bedroom Hot Tub Barn in Llanellen

Big Pit is a real coal mine and one of Britain's leading mining museums, standing on the heather-clad moors above Blaenavon. It worked as a colliery from 1880 to 1980 and opened to the public in 1983. The star attraction is the Underground Tour, which takes you 300 feet down with a real miner to see what life was like for the men who worked the coal face.

Tip: Underground tour places on the day aren't guaranteed a time slot and queues can build when busy, so book a timed Job-A-Knock ticket in advance to secure your spot.

Raglan Castle sits just north of the village of Raglan in Monmouthshire, south east Wales. Built and rebuilt between the 15th and early 17th centuries by the Herbert and Somerset families, it was once a luxurious, fortified home, and its large hexagonal keep is known as the Great Tower or the Yellow Tower of Gwent.

Llanthony Priory is a partly ruined Augustinian priory in the secluded, steep-sided Vale of Ewyas, in the Black Mountains area of the Brecon Beacons National Park. Founded around 1100, it became the first priory of Canons Regular in Wales and grew into one of the great medieval buildings of the country, mixing Norman and Gothic styles. The main ruins are cared for by Cadw.

Tip: The priory is about seven miles north of Abergavenny on the old road towards Hay-on-Wye, so allow time for the winding valley drive.

Goodrich Castle is a ruined medieval fortress on a rocky sandstone outcrop above the River Wye, near Ross-on-Wye. Begun after the Norman Conquest, it grew into a stone castle with a square keep, big corner towers and a gatehouse with a barbican. William Wordsworth called it the "noblest ruin in Herefordshire".

Tip: Book advance tickets online through English Heritage, and pick up the family game from the ticket office when you arrive.

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.

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".

Bristol Zoo Project is a wildlife conservation park in South Gloucestershire, run by Bristol Zoological Society. It covers a large site, and its areas are designed to link ecosystems and conservation programmes around the world. Current areas include Bear Wood, Benoué National Park and Discover Madagascar.

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.
