We have just returned from an 18 day trek to Gokyo and Everest Base Camp. We travelled as two families with four children aged from 10 years to 15 years old. We had originally planned to trek from Gokyo to Lobuche via the Cho La Pass, but on the advise of our wonderful guide we amended our plans and trekked via Phortse, Pangboche and Dingboche instead. Definitely the right choice when we spoke to others who had attempted the pass - very icy.
We cannot speak highly enough of Hari - he was an amazing guide. Always willing to share his expertise, with over 30 years of guiding. He knew all the best places to stay, and acquired the best rooms for us (some even with an ensuite toilet!!). He gave wise advice on staying fit and healthy, to the extent that no-one went down with gastro, and we all acclimatised well to the altitude with a sensible pace. We would absolutely recommend taking Environmental Treks - Nava gave great advice before we left, as there were concerns regarding the aftermath of the earthquake. We needn't have worried as lodges and tracks to Gokyo and EBC were all in excellent condition. Hari somehow engineered a special meal for us to celebrate Christmas - greatly appreciated and fondly remembered. Thanks for your leadership and friendship Hari - if you're travelling with kids then your best move would be to ask for Hari.
