We are in Arequipa and the weather here is sunny and warm, with lovely clear blue skies. Not far away there is a volcano that has started to smoke and in the nearby central highlands there have been some unseasonal and heavy snow falls. We journey from Arequipa to Puno tomorrow but thankfully we are not going by road. We fly early in the morning and we'll let you know in the next blog how we get on! If you don't hear from us we are either stuck in snow or the Internet doesn't work well. If it is the Internet, don't worry, we'll catch up in a day or two. If it is the snow, don't worry, Richard has a spade.
