It’s undoubtedly challenging but exceedingly rewarding. Good combination of dramatically high mountains and rural villages of Nepal. The trek leading to Thorangla pass is a memory for a lifetime. Crossing high pass over 5000 meters is more of a personal accomplishment for me. Glad to make it with mild Acute Mountain Sickness. My first 2-weeks long trek in the Himalayas and felt like my training in gym and day hike in weekends back home helped me a lot.
