After visiting so many trekking agency and reading so many online review on trip advisor.com, we chose welcome nepal treks for our Everest base camp trek. Mr hair was the great organizing the trek for us and made sure we met our guide and porter at arrival day at hotel lobby. Our guide Mr Rajan was very experienced and has been to Everest base camp many time before. We would like to to highly recommend Mr hair owner of this company and welcome nepal treks. We are already thinking about the next trek with them, thank you so much.
