A total 21.4 million of them were domestic tourists, while the remaining were foreigners, Pintu told reporters here.
The tourists' inflow in Bihar last year was higher by about 20 per cent in comparison to the 1.83 crore in 2011, he said adding the government was happy with the increased inflow of tourists in recent years.
However, the government would like to build infrastructures like roads, transportation, communication networks, hotels and related facilities to lure more tourists to Bihar in future.
