Do you have any advice for potential travellers?
Key advice is to make sure you have the right clothing for the trip, the weather is really very unpredictable. So definitely take waterproof trousers and a balaclava, woollen mittens and a hat that covers up your ears and will stay on in a blizzard. Also a waterproof bag and waterproof case for your camera.
It can be sunny one minute, then hail can smack you across the face the next, and then it's snowing!
Embrace the unpredictability of the trip and don't be disappointed if things don't go according to the itinerary.
