Wales Ape and Monkey Sanctuary sits between Caehopkin and Abercraf in Powys. It began as a hill farm and grew into a final home for unwanted primates, including chimpanzees, baboons, spider monkeys, capuchins and marmosets. Its first chimpanzees arrived in 1999, when seven were taken in from Penscynor Wildlife Park after it closed.

Zip World Tower is an adventure park on the site of Tower Colliery near Aberdare, which was the oldest continuously working deep-coal mine in the UK until it closed in 2008. The preserved mining structures surround the rides, so you get a good look at the history as you go.

Tip: Book in advance, and arrive 30 minutes before your start time. Wear warm clothes with boots or trainers, and no sandals or open-toe shoes.

Hay Castle is a medieval fortification with a 17th-century mansion alongside, right in the centre of the book town of Hay-on-Wye. Founded by the Normans and rebuilt in stone around 1200, it has been attacked and burnt several times over the centuries.

Tip: Use the large public car park off Oxford Road, which has free electric vehicle charging points. Dogs must stay on a lead, and are welcome on the ground floor, in the café and in the grounds.

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.

The National Waterfront Museum in Swansea's Maritime Quarter tells the story of industry and innovation in Wales over the last 300 years. It is part of Amgueddfa Cymru – Museum Wales, housed in an original listed warehouse linked to an ultra-modern slate and glass building.

Tip: There's no dedicated car park, but several pay and display car parks are a short walk away. For satnav, the museum's site suggests postcode SA1 3ST.

Swansea Museum is the oldest museum in Wales, opened in 1841 in a Grade II* listed neo-classical building in the Maritime Quarter. Its six galleries hold objects from Swansea, Wales and the wider world, with everything from an Egyptian mummy to a Welsh kitchen. Temporary exhibitions change through the year, so there is usually something different to see.

Tip: Parking at the museum is limited to a few free spaces, so the City Gates NCP or East Burrows Road car parks, both about a 4-minute walk away, are a good fallback.

Carreg Cennen Castle stands on a high rocky outcrop above the River Cennen, near the village of Trap and four miles south east of Llandeilo. It sits within the Brecon Beacons National Park and is cared for by Cadw. The castle you see today was probably built by John Giffard and his son after Edward I's conquest of Wales.

Tip: The castle is reached by a steep climb up the hill from Castell Farm, near the car park, so wear sensible footwear.

The National Botanic Garden of Wales is in Llanarthney, in the River Tywi valley. It is both a visitor attraction and a centre for botanical research and conservation. The centrepiece is the Great Glasshouse, the world's largest single-span glasshouse at 110 m long and 60 m wide. It stands virtually on the site of Cockerell's mansion, the new Middleton Hall.

Tip: Look out across the restored eastern view towards Paxton's Tower, which was designed to be seen from the mansion's east side.
