I booked my trip with Passang as single female trekking, to sleep at Everest Base Camp. He was very organized, very thorough and answered all my questions immediately. Our lead guide and assistant guide were amazing and made the trip very enjoyable. The two porters were like magic elves carrying and delivering my bag from one village to the next. The trip was fabulous… Definitely a trip of a lifetime. I would highly recommend Highland Expeditions. Their expertise, knowledge and organizational skills are what you need for a trek like this.
