Rolwaling and Everest base camp trek is a 21 days trek with 3 camping nights that runs through the upper section of GHT connecting the Gaurishankar conservation area and Sagarmatha national park. This is a moderately difficult trek that involves camping on the glacial moraine, vertical climbing, and crossing the Tashi Lapcha pass at an altitude of 5,750m.
The trek first starts with a bizarrely remote Rolwaling valley walled by the crystal crispy peaks dominated by the holy Mount Gaurishankar 7134m. The GMT of Kathmandu has been referenced to the summit of Gaurishankar. In the valley flows the Rolwaling river directly descending from the Tsho Rolpa Lake. By the side of the river are the villages of Beding and Na, with no electricity, network, tourists, and only a few people. You will camp by the Tsho Rolpa Lake, melt ice for water, and advance through the constantly crackling glacial moraines. You will have to fix ropes and climb 100m vertically and camp at the windy and snowy Tashi Lapcha pass. You may spot mountaineers clinging on the Pachermo peak. By the time you reach the pass, you will be completely exhausted and as the night falls those beautiful mountains begin to look like giant ghosts in the dead cold darkness.
The next day you wake up amid the tallest natural skyscrapers with the floating clouds gazing at the golden sun rays on the silver mountains. Descending down you will enter the Sagarmatha national park with improved trails, teahouses, and the highest mountains. You will trek by the beautiful Gokyo lakes, cross the Cho La Pass 5,420m, and get to the Everest base camp. You will stay overnight near the Everest base camp and hike to Kalapatthar for the iconic view of Mount Everest. You will continue trekking through the Pheriche below the towering Amadablam and get to the Namche Bazar via Tengboche. From Namche Bazar, you will trek to Lukla and take a flight back to Kathmandu.
