We just returned from a 13 day trek and really liked Nepal Environmental. We were already in nepal when we searched for a reliable company and honestly after showing up at several different agencies, Nepal Environmental was the most professional, friendly and affordable by far. Our package included everything from jacket rentals to airport transfer and yeah, we were happily surprised how comprehensive they were based on their price point. Our guide Hari was amazing. He has over 30yrs of experience and was very attentive about our health/acclimatization pace. He's also just a really sincere and good person and was knowledgeable about the life, culture and history of the Himalayan region/communities. Hari speaks English really well and is super easy to get along with. One thing to note is that Lukla airport had halted flights for about 4days due to weather and Hari made the suggestion to take a Jeep into a town called Phaplu so we could stay on schedule. Best decision ever. Phaplu was a really challenging trek but we were able to really interact with Nepali folks and be far away from the hyper touristy trail. Our schedule was flexible and Hari adjusted it based on our health ect. Overall, amazing time. Highly recommended.
