The ' Yakshi,' the concrete sculpture of a legendary enchantress done by Kerala's best-knowm sculptor Kanayi Kunhiraman, is one of the major attractions here. This is the nude figurine of a giant woman, head flung back and hands poised to tear her hair, in sensuous exuberance and power. The Yakshi is an appropriate adornment to the glory of the landscaped gardens and the dense natural beauty of the Malampuzha Dam, called the 'temple of modern age' by Pandit Jawaharlal Nehru.

An interesting feature of the rock garden is that it is made of and decorated with unwanted and broken pieces of bangles, tiles, used plastic cans, tins and other waste materials. The garden is a master work of sculptor Padmashree Neck Chand Saini. His best work, the rock garden in Chandigarh, is world famous and attracts thousands of tourists every year.
