My friends and I went on a 6 day trek with Shiva in the Annapurna mountain range. It was the best thing I have done in my life so far. Shiva was a very pleasant companion (even taught us a few Nepalese folk songs). He knew the trail and the mountains very well, and was able to answer all of our questions (he knows everything about each mountain you might see during your trek) I highly recommend Shiva to any trekker interested in going to Nepal!
