We used Protrek Adventure for our trekking trip to Nepal. It was a wonderful and enjoyable adventure. The prompt response to emails was the first thing that impressed us. The entire trip was meticulously planned. The guides and support staff were all nice and helpful. And we are glad we chose them 🙂 The tea houses where we stayed on the trek were excellent and of high quality. It was an overall well-organized trip. I highly recommend them for trekking and mountaineering.
