I am saying this frankly! The trek is strenuous as you trek to the base camp of Kanchenjunga through rougn-n-tough trail. I walked for at least 5 hours for many days. Some of the villages were isolated and with very limited facilities for trekkers. Thank god, the guide managed everything perfectly, and I guess that's how we can distinguish a good travel company from bad. From the first day to the last day of the trek, I was cared and provided good options. I was lucky that I got to view stunning views of Kanchenjunga and other peaks. Glad I did this trek.
