Our trip from Kathmandu to Everest Base Camp, Kala Pattar, Cho La Pass, Gokyo Ri and back to Kathmandu was a total success due to the organisation and guidance of Adventure Thamserku. The leader Dawa Geljen Sherpa and his Sherpa guides, cook and porters were truly professionals of the highest standard. I would recommend this trekking company to any group or individual that is planning to trek, climb or mountain bike in Nepal or Tibet.
