Janardhanaswamy Temple in Varkala is located 25 km north of Thiruvananthapuram. The temple is dedicated to Lord Vishnu, and the annual Arattu festival held here draws thousands of devotees. It is an ancient temple dating back around 2,000 years. Varkala has been a Hindu pilgrimage site since the 12th century, and the temple was built during this period.
The Varkala sands have become an ideal spot for confluence of various cultures. Varkala also houses a leading pilgrim centre in Kerala. The temple, dedicated to Lord Vishnu and Hanuman, atop the hill has brought a sobriquet for the region, Southern Kasi (Benares). Non-Hindus are not permitted to enter the inner sanctum but can hang around the temple.
