Simply the best in the business.

We climbed Lobuche East, Manaslu, and Everest with SST. The quality of guidance, Sherpa support, training, and service was second to none.

Due to Covid, we had to combine our Lobuche and Manaslu expeditions, normally this would be a huge logistical nightmare for any other company, SST have the team size, logistic support, and experience to make this happen…. All of this was also done during the lockdown. We were in a unique position being a national team, we could isolate ourselves before travel and upon arrival in Nepal, we had no fixed timeline to meet and had the use of a military aircraft for travel so SST presented this to the Nepalese Government who agreed to use us as the test case and allow us to climb in autumn 2020 and see if it would be possible to open the Khumbu for the spring 2021 season.

Both Lobuche and Manaslu were a huge success, the basecamp and higher camp setup were fantastic, the staff was amazing throughout and it made us look forward to Everest.

Everest was even better, the training, trek, and climbing were fully supported, we didn’t have to ask for anything, SST fixed the ropes to the summit and planned our climb perfectly, and we were the first team to the summit on the first day of the first weather window… couldn’t have planned it any better. We felt fully supported and safe throughout!

We went for an all-inclusive package so booked all of our travel, insurance, kit and equipment, full basecamp and climbing service included, as well as a full 90-minute documentary made by their climbing camera team.

Overall an amazing company that I would thoroughly recommend to everyone, their experience, skills, reputation, and connections within all levels of government mean they can provide what others can’t…. Don’t always believe the hype around other companies…. They’re almost always on an SST permit, using SST Sherpas and base camp staff and use SST to set up their base camps, etc… around 50% of climbers on Everest in 2021 were on SST permits.
