For Delhi-based Nupur Singh, 55, a few days of work-related travel to Bhutan way back in 1995 translated into wanderlust for life. She was mesmerised by the beauty of the hills and went back on a personal solo trip to explore the country. Eventually, she fell in love with the idea of travelling on her own. Singh now runs a Delhi-based travel company, Triponary, which offers experiential trips to students, women, and corporate groups.
