Great place for trekking
I was in Nepal for about two weeks for Everest trekking. In Kathmandu, they don't have traffic lights. They have traffic police to manage the intersection. So, traffic is quite chaotic.
Insider Tip:Some shopping tips if you're going to trek: 1. Get a travel insurance. 2. I came from the states. I found that it's cheaper to just get your trekking gear from the states. You can save money by buying quality gears from used stores such as Goodwill or Ebay/Amazon/Craigslist. 3. Chocolate candies are also more expensive here than in the states. Nepal imports them from other countries.
