Do you have any advice for potential travellers?
Layers - I didn't bother with a down jacket, i know my body varies in heat, so I layered up and peeled of as and when required.
Thermals& Fleece - Invest in decent merino wool layers. I purchased Icebreakers, they were smell proof and well insulated...well worth every penny.
Snacks - you will always get to buy snacks along the way, it's good to contribute torwards the local economy, so don't get too bogged down on buying and bringing snacks from home.
Water - Handy to bring water purification tablets, there are safe water drinking stations along the way (not at every place, so please check with the guide in advance)
Food - Never had any problems and enjoyed every meal, there was a varied selection. Daal baath, is always the safest option for protein and plenty inclusive refills. Try the different teas at the teahouses. I recommend purchasing peanut butter to add to your toast/rotis at breakfast.
