Day 1
Start your tour with a visit to Dyffryn Gardens just outside Cardiff. Work began in 1997 to restore this Grade I listed Edwardian garden to its former glory. You will find over 30 different themed areas amongst broad sweeping lawns including - the famous Pompeian garden, theatre garden, cloister garden, rose garden, and exceptional arboretum containing many rare trees.
Spend the rest of the afternoon wandering through 1000 acres of historic parklands and ornamental gardens at Margam Park. Visit the magnificent 18th century Orangery, Tudor-Gothic style Victorian Mansion House, and 12th century Chapter House. Look out for the deer herd roaming through the grounds.
Day 2
Today starts with a visit to The National Botanic Gardens at Llanarthne. The first botanic garden in the UK - dedicated to conserving plant species. Set in 600 acres of 18th century parkland with exotic flowers and foliage, lakes, waterfalls and cascades. The centrepiece is its impressive great glasshouse – the world's largest single span glass structure.
From here it's just a few minutes to Aberglasney Gardens in the beautiful Tywi Valley, Carmarthenshire. Described by many as The 'Garden lost in time' - it is a jewel in the British gardens' crown. Covering approximately 9 acres, including two woodlands, it has a unique Elizabethan and Jacobean cloister garden. Spring is an ideal time to visit when many of its rare spring flowers are in full bloom.
End the day on a romantic note by exploring Wales' most dramatically sited castle Carreg Cennen. It sits on a limestone crag 300 ft above a sheer drop to the river Cennen below – so be prepared for a steep climb to the top.

Your last stop is Llanerchaeron, an unusual National Trust property just outside Aberaeron.
