The tour, of sites mentioned in the Ramayana legend, is part of a marketing effort by the island's tourist promotion agency to increase the number of visitors from India, which has emerged as a key tourism market for Sri Lanka.
"A big increase is expected in the Indian outbound tourism market," Kalaiselvam told a conference for American investors.
"We being close to India will benefit from that increase."
Kalaiselvam said the 'Ramayana trail' tour package was well positioned to draw Indian visitors as there was no competition for the product.
"A group of 500 visitors is expected from India in December, and in January we expect a 1,000-strong group."
The tourism authorities are developing a host of sites depicted in the Ramayana, the ancient Sanskrit epic popular especially among Hindus, ranging from jungle shrines to mountains, streams, and caves.
The poem tells the tale of Rama, an incarnation of the Hindu god Vishnu, whose wife Sita is abducted by Ravana, the demon king of Lanka.The number of tourists visiting the island has increased sharply since the end of its 30-year ethnic war in May when government forces defeated the Tamil Tiger separatists.
The war had been the main deterrent to tourists.
The Sri Lanka Tourism Development Authority has said the island hopes to attract 2.5 million tourists by 2016 and has launched several projects to increase the number of rooms to cater to the anticipated numbers.
Tourist arrivals into Sri Lanka in September 2009 rose 28.6 percent to 37,983 from a year ago, with strong growth from key European, East Asian and south Asian markets, the Tourism Authority said.
It was the fourth straight monthly rise in visitors since May, with a big increase in arrivals from India, a tourism market that has been growing in importance in recent years.
