I did a longer version to EBC (21 days). Highly recommended. Great experience. The scenery is incredible. You stand at an altitude of 4,000 meters and all around are mountains that are another 4000 meters higher. I have known the owner for a long time and I can only recommend him. A very smart guy; Krishna, the guide, is very recommended too. They always take care of you. The company is an excellent choice for trekking in Nepal!
