The trek is far from transport and normal infrastructure, taking in tiny settlements and mountain pass trading points along the route. High-slung rope bridges cross deep glacial river valleys and the giant peaks of Everest, Nuptse, Lhotse, Ama Dablam are a constant backdrop to colourful Buddhist prayer flags and monasteries.

The terrain is mountainous and changes daily with incredible views if you are not climbing through cloud at the time! The team hope to Summit above 5,400 metres (18,000’) where sub zero temperatures and oxygen parched air make progress slow but rewarding.

The team will learn about the culture and people along the route, sharing with the Sherpa people and meeting other races dependent on the mountain trade routes to maintain their wilderness way of life. The expedition is not for fundraising, but is contributing to environmental and micro economy projects in the Sargamatha region. The expedition will be carbon neutral and subject to environmental impact and comprehensive risk assessments.

Whilst the primary aim is to complete the base camp trek and a series of peaks en route, there is a further goal. The team have specialist skills to carry out an intrepid attempt at a World First with Girlguiding's new hot air balloon if conditions allow. Details of this will be updated as we go, so watch the site as time goes by.

This will be a bunch of Girlguides showing what their developing skills, training and support can achieve in a world challenge. Discover your potential.
