The Arun valley provides really superb views of both Mt Everest and Mount Makalu. It is located between the Sagarmatha andMakalu-Barun National Parks. Trekking in this valley provides an alternative approach to the Khumbu region. We recommend this approach to those people who have already been in the Everest region and want revisit Everest Base Camp (Kalapattar) via a less traveled route. The trek requires stamina and fitness to fully appreciate the beauty of the region, which provides some outstanding mountain views. Commencing with a flight to Tumlingtar to the East of Everest, the first week is spent trekking through virgin territory into the Solu Khumbu region before a push up on the main Everest trail to Kallapattar for tremendous close ups of Everest Nuptse and Lhotse along with many others before a journey back to Lukla and a flight to Kathmandu.
