Welcome back to the Good Trekker Series. We're pleased to introduce our newest expert, Dr Yak! No one knows about living at high altitude like a yak and this yak has all the answers. We are also introducing our new Altitude Tip cards. A version of the card will be distributed to all three clinics this spring run by the Himalayan Rescue Association (HRA) in the villages of Manang in the Annapurna region and Pheriche on the Everest trek. They will also be available at Everest ER at Mt Everest base camp. Make sure you visit these hard working doctors at the clinics and ask for your Musa Masala Attitude Tips card!
