If you are going for a week, or even for two months, and want to experience everything Nepal has to offer without the hassle of looking for the right hotel, competent guides, where to catch your bus, or want to discover that marvelous hidden stupa which everybody talks about without getting lost in interwinding streets, then your best bet is to have your trip organized by agencies in Nepal. You can join a package tour, or have one tailored to your specific needs so as not to worry about the day-by-day arrangements.
