2015 Nepal Trips

Tenzing-Hillary Everest Marathon

Run the world's highest marathon and support post-earthquake relief funds.
September 21st - October 10, Race day October 5

Starting at Mount Everest Base Camp (17,500 feet) the Tenzing-Hillary Everest Marathon is the WORLD’S HIGHEST MARATHON and one of the most adventurous trail runs in the world. Due to the earthquakes that shook the region in spring 2015, we've moved this year's marathon from its usual date on the anneversary of the Tenzing-Hillary first ascent to the fall. The upcoming race on October 5, 2015 will be the 13th edition of this annual race held since 2003. This marathon is an international event with runners from over 20 countries competing each year.

Ultimate Annapurna Trek

Hike from the Himalaya foothills to the high passes of the stunning Annapurna region.
September 18th - October 10th, October 9th - 31st
November 6th - 28th, November 27th - December 19th

The classic Annapurna Circuit trek first became accessible to the world of adventure travelers as recently as 1977, when the Nepalese Government derestricted the Manang Valley, which had previously been closed on account of its proximity to the Tibetan border. Providing a combination of spectacular high mountain scenery, picturesque lowland farms and villages, a wealth of cultural interest and a challenging pass crossing, the Annapurna Circuit trek is justifiably popular. We start out from Besisahar, ascending the surprisingly wild and unspoiled Marsyangdi Valley to reach the north side of the Annapurna Massif. In terms of its sheer scale, the valley of the Marsyangdi is unsurpassed. Throughout our walk, we enjoy regular contact with friendly villagers, as well as ever-changing panoramas of some of the world's greatest peaks, including Manaslu and the Annapurnas. See the One World Trekking website for more details.

Lost Valleys of Narphu Trek

Get off the beaten path in the magical valleys of the Narphu region.
October 3rd - 23rd
This unique and seldom traveled route offers the adventurous trekker a bit of everything that makes Nepal so special. From Besisahar, we will gradually ascend the Marshyangi River Valley to Koto. Here, we head northwards and enter the recently opened NarPhu Valleys of Upper Manang. Passing through the chorten gate that designates the entrance to NarPhu, it's as if we've been transported into a land where time has stood still. The Himalayan Pine quickly give way to high plateau, remote Tibetan villages built of stone, ancient Buddhist monasteries and grand views of the Annapurna Range. See the One World Trekking website for details.
