I'm an old client of Third Rock; I've been doing trek with them since 2017. I knew Naba from 2015. I have done Annapurna Base Camp Trek, Tilicho Lake Trek, Kathmandu Valley Tour, Chitwan tour and Upper Mustang Trek with them. And this time I did Tengboche Monastery trek with them. As always they took care of me and let me enjoy the trek to the fullest. The guide are professional and caring. I would always highly recommend Third Rock Adventures to anyone who wants to explore Nepal.
