CIRCUIT GOKYO ~ CONNECTING NANGPA, GOKYO, THAMCHO VALLEY ~ NEPAL, MAY 2023 What happens when you successfully explore a new col, when you connect another known pass with it to connect three valleys and make a circuit trek, when you trek through a virgin route and valley and view and capture some breathtaking sights, with excellent landscapes, towering Himalayan peaks of Nepal and Tibet, adventurous trek route, crossing a new col, flora, and fauna, get to meet some world-famous sherpas (some ... See more who have climbed Mt. Everest 22 times and all the 14 eight thousand peaks), know about the local habitats ?? ~ it was something which will be cherished for long. Above all, when the highest authority of Nepal Trekking and Expedition, TAAN (Trekking Agencies Association of Nepal) acknowledges us with an appreciation certificate for our exploration, the joy is much sweeter. Along with Partha Sarathi Moulik, with the able guidance and support of Mr. Binod Karki (he was with us who guided) of Himalayan Adventure Intl Treks and one porter, we self-supported and conducted with GPS and map, successfully explored and crossed a new col, for the first time ~ THONAK LA (5416 m), on 29th May 2023, which connects Nangpa Valley with Gokyo Valley, to reach Thonak Tso and then Gokyo Lake. This col is not so technically difficult to cross from Nangpa to Gokyo Valley as the other passes in the nearby area, which are technical. Then trek from Gokyo Lake to Thamcho Valley by crossing the known Renjo Pass (5435 m) on 31st May 2023. Thus, we connected the three beautiful valleys of the Khumbu area in Nepal, namely Nangpa, Gokyo, and Thamcho Valley in a circuit named GOKYO CIRCUIT. Thamcho and Nangpa Valley are less visited, Becoz, only when a few trekkers complete two passes Tashi Lapcha which ends at Thame, and Renjo Pass which ends at Lungden and Thame. Nangpa Valley is hardly visited. Thus, this beautiful, adventurous but much easier trek route can attract many trekkers tourists in the future. Our route was Salleri ~ Thamdanda (jeep) ~ Paiya, Chheubas ~ Phakding ~ Namche Bazar ~ Thame ~ Lungden ~ Sumna Phu ~ cross new col Thonak La ~ Thonak Tso ~ Gokyo ~ cross Renjo Pass ~ Lungden (lunch) ~ Thame Teng ~ Namche Bazar ~ Lukla ~ Kathmandu See less...
