Kanchenjunga Himal is very remote area of Nepal. Kathmandu to Taplejung daily bus services are available it takes at least 2 and half day to reach Taplejung (trekking starting point) but Trekkers choose flight to Biratnagar then Suketar airport near by Taplejung for their luxuries Journey because overland tour is very worse. Kanchenjunga area people they established the lodge facilities but it is very normal accommodation and meals available so wesuggests book the trekking as camping (Tent to tent camp) that makes your holiday better.
