I am lucky enough to have traveled by helicopter to Everest base camp and Kala Patthar. I was planning this trip for a long. But, I finally made it this year. Thanks to Naba for putting effort into making my trip on fixed departure dates. The sightseeing experience was unmatched. Omg! Everest was humongous from Kala Patthar. The Khumbu Icefall, glaciers, and moraines, all were inspiring it a great experience. Also, the rate was affordable. I am planning for the Annapurna Base Camp trek this year autumn season. Can't wait to be back in Nepal and I will choose them again and for every Nepal adventure.
