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.

The expedition was organised by Adarsh Tours and Travels, an agency promoting mountaineering in Sikkim.

Allenbach is an Everester, having scaled the highest peak (8,848m) in the world way back in 1978. A technical engineer by profession, Allenbach has also participated in a number of expeditions in Ladakh.
