Gangtok, Oct. 28: A Swiss and Dutch team has conquered the 6,010m-high Mt Thingchingkhang in West Sikkim. This is the third successful ascent to the peak in just over a year and is expected to give a big boost to adventure tourism in the state.

The expedition led by the 57-year-old Swiss mountaineer Robert Allenbach included his wife Susana Cornelia, a medical assistant, Robertus Laan, a Dutch national living in Switzerland and Paul P.E. Van Rivere from the Netherlands. They have returned to base after reaching the summit earlier this week.
