These 19th Century landscaped gardens of 50 acres contain probably the finest collection of rhododendrons in Wales, including some which grow to 16m high. They were established by the wealthy Vivian family who organised expeditions to collect exotic plant specimens from abroad. Interesting areas include the bog garden, lake and waterfall with Japanese Bridge. There is also a bluebell wood and wildflower meadow. During May, the “Clyne in Bloom” Festival is celebrated here, with many fun activities.
