My stay in Nepal and the trekking tour via Namche Bazar to Kala Patthar as well as via Cho La Pass to Gokyo and back to Lukla was a wonderful and unforgetable experience thanks to Nepal Holiday Trek and Tours. The tour was very well organised and everybody was very friendly and helpful. I had an exellent guide with a long experience who explained a lot in good English. He also made sure that I could carefree enjoy the fantastic nature (e.g. with calling at tea houses to reserve rooms prior to our arrivel). Talking about nature, the scenery on this tour is truely stunning: high mountains, glaciers, green valleys, clear rivers, breathtaking views. Sadly I stumbled over some hidden piles of rubbish in the middle of nowhere and with some distance to villages. So to all the trekkers out there: Please avoid buying plastic bottles (tap water can easily be treated) and take your rubbish out of the beautiful mountains (rubbish thrown in bins at tea houses might end up on those piles). I warmly recommend booking this tour with Nepal Holiday Trek and Tours.
