I recently completed a trek with 4 mates through Luxury Holiday Nepal. We Flew into Lukla and trekked from there to Gokyo (climbing Gokyo Ri)and up the valley to Everest Base Camp and Kala Pattar. The organization of the trek was very good, and the assistance we received from our guide. They were meticulous in preparing us for the altitude we had to face. Our acclimatization was very carefully managed for climbing Gokyo Ri, and Kala Patthar and their attention summit day was excellent and an effort in getting us out of EBC at the end of our trek. The guide did everything possible to ensure that we arrived back in Kathmandu for our international flights. Next time I travel to Nepal I will be arranging my trek through Luxury Holiday Nepal and requesting the same guide.
