Third Rock exceeded my expectation. I never had imagined such service from local travel agency in Kathmandu. The guide were experienced with brilliant history of trekking in Nepal. Naba was friendly and quick to address all my queries. We talked over Whatsapp to ensure everything was going great. Before I book, I checked their reviews and found it genuine and a deciding factor to go with them. I loved the adventure, all thanks to my hardworking guide Bimal and Naba for operation in the background.
