Hi Jonathon, I'm looking to travel in December the Annapurna circuit alone. I've seen your post you did January 2009 about whether it's safe to travel alone. Do you mind if I tap into your knowledge? I felt you had the same questions/reservations the first time round that I have now on my first possible excursion to Annapurna. My key areas of concern are: (1) My average altitude will be 2500m - 3500m, I would take a tent. The suggestion has been that the temperatures won't drop dangerously low at night. What temperatures have you experienced at night at these heights in January? (2) What was your average altitude in Annapurna, and how did you find the prospect of dealing with altitude sickness alone? This worries me a lot out of most. (3) What is your opinion of alone trekking in Annapurna, do you think it's dangerous? (4) How are locals with tourists? Thanks for your help in advance if you have the time! Regards, Antony
