A legacy of 46 years and still continuing, Ratan Lal Biswas is a name distinguished in all variants of trekking and mountaineering.

His journey began with a formal trek to Alpathra Lake Trek and Sandakphu in the year 1972 and in 1973 during his third year in college, together with a newly met acquaintance, he went to trek in the Gangotri and later the Pindari Glacier. Later on he was to meet Kanailal Ghosh, the man with whom he would be exploring new mountain routes and other places in the Western Nepal and more.

This year in 2017, Mr. Biswas has crossed a milestone of 100 treks, which include the Himalayas, coastal area and the desert. In this 45 years of time span, his journey has been wonderful and inspiring. We, Top Five Buzz team congratulate him and wish him all the best for more years to come.
