I would highly recommend Happy Treks. Myself and friend went on a 3 day trek to Poon Hill with trekking guide Prem and porter Ramesh. A fun and fantastic experience made even better by such an experienced and knowledgeable trekking guide. The company is well run and very helpful with any questions or concerns you have before, during or after the trek. Both guide and porter were very helpful along the trek and went at our pace. Poon Hill was beautiful, we had an amazing time with amazing and humble people.
