I have done the EBC trek twice with Ace the Himalaya. They are a fantastic company to trek with as they take care of every single detail for you. All you really need to do is arrive at Katmandu International Airport and they take very good care of you for the complete time in Nepal. I have used the same guide Milan A and I will always request him because of his knowledge, experience and relationships with the business owners along the trail. He got this 65 year old up to EBC twice so he is a master at motivation and empathy. I expect to do Langtang Valley with him next year. I highly recommend Ace and Milan as you can’t find any better in Nepal.
