Tamil Nadu is a perfect place for a pilgrimage tour where the vibrant Hindu temples are not only the haven to seek spirituality but to be in awe of the imposing architecture and rich culture as well. Otherwise a sultry destination, Tamil Nadu is sparsely dotted with some of the most beautiful hill stations like Ooty and Kodaikanal that make an ideal escape during the peak summer season. The famed UNESCO World Site, Nilgiri Mountain Railway, monuments of Mahabalipuram (Mamallapuram), Chola temples at Thanjavur, Darasuram, and Gangaikondacholapuram simply add to Tamil Nadu's tourism.
