Kochi, Aug 19 - Nine years after they quit the Indian Navy, two men here are basking in the success of the adventure tourism company they started in Kerala, with their innovative products even fetching them an award this year.

Commander Sam T. Samuel, 50, managing director of Kalypso Adventures, who is a former naval pilot with over 4,000 hours of flying experience, told IANS he has no regrets over quitting the navy because their company is doing roaring business.

'Our latest products - 'voluntourism' and 'accessible tourism' - have started reaping clients, especially from the UK. For voluntourism, we have tied up with UK-based World Challenge Youth Organisation and Raleigh International and we have already handled a group of 100,' said Samuel.

He started the company along with Commander Thomas Zacharias, a former electronics engineer with the navy, who is executive director of the company. Both put in 20 years of service in the navy.

Kalypso Adventures was declared winner of the award for Innovation in Adventure Tourism 2009 given by the Adventure Tour Operators' Association of India.

As part of the company's 'voluntourism' offer, those looking to fulfil corporate social responsibility or even otherwise come here to do some sort of voluntary work, be it painting a school or building a compound wall or any sort of physical activity. This segment attracts people from abroad in the age group 18 to 24.

Spread over a period of more than 10 days, a group splits its time between physical activity and travelling and exploring the beauty of the state.

Another tourism product which has now been accepted is their effort in chalking out packages for physically challenged travellers from abroad - as part of 'accessible tourism'.
