Trekking in Eastern Nepal includes an eastern approach to Everest. This region is very isolated but has some of the the best trekking in Nepal. The most popular areas for trekkers is the Makalu Barun National park on the border of Tibet and the Kanchenjunga massif on the border to Sikkim. Trekking to the very remote Makalu (8475 m) and Kanchenjunga (8598 m) base camps are two of the finest treks in Nepal. This area is rarely visited by trekkers and this is an area with diverse and colorful culture at the lower elevations and rich in wildlife at the highlands. To make trips to eastern mountains, either domestic flight or long journey by bus is necessary. The main domestic airports are Tumlingtar, Lamidada and Taplejung which have direct connection with Katmandu.
