I have just returned from this trek and after many years of travelling with Exodus I have to say that this trip is second to none and is far better than the Everest region, or Nanda Devi. Being a circular trip you are able to have an amphitheatre of high peaks over 7,000m+ nearly every day, once out of the initial valley. The daily walks were very varied with steep ravines, village life and extraordinary mountain ranges in front and behind you. The days are long in the beginning but you always have something to look at that makes you smile. Some of the tea houses are very basic the higher you go and make sure you have warm gear for the evenings. Gaining altitude is gradual with half days and afternoon walks to acclimatise you. The very early start to get over the pass was very cold and a tough day but if the weather is good the scenery is superb. Be sure to have a good working head torch with lithium batteries. If you area seasoned trekker do this one. You will not be disappointed. Do not lave it too long as the Nepalese are likely to get the road built and this valley will become like Annapurna and possible spoilt for those that like remoteness with beauty.
Great experience. If you're not afraid of the somewhat basic lodging conditions, you'll not be disapointed. Landscapes are so dramatics, with so many nice little villages and not a lot of trekkers on it. Do it before it becomes too popular (which it will be soon, I'm afraid!)
Gokyo and Everest Base Camp We all around loved our trek in the Everest region. Chaatra was there to greet us in Kathmandu and Ram and Thukpa were our guides for 12 days. Even though winter had not quite left the Himalayas when we were there (March 2015), everything went smoothly. We acclimatized slowly so we did not get altitude sickness and were healthy throughout the trek. Our guide Ram knew the region, trails, and teahouses well. He spoke English well and explained which peaks were which and answered all our questions. Thukpa, our porter, was strong and patient. He didn't even complain when we had to change routes (Cho-La pass was closed due to snow, but we still wanted to see both Base Camp and Gokyo Lakes. We appreciated the flexibility in our schedule, which allowed us to go faster when it made sense to. Overall, I would give Nepal Eco-Adventures and unreserved recommendation.
