Munnar is one of best hill station of India. Sprawling tea gardens, lush evergreen forests, dams, waterfall and what not. The tea museum is very unique and informative esp about the importance of green tea. Speed Boating in Mattupatty dam is one of the best experience. You can enjoy the elephant safari also. Eravikulam national park is the only place where you can spot the famous nilgiri gaurs. The best season is obviously winters but it is dependent on ones own choice. Munnar is the must go for the travellers.
