This is 3rd time that Third Rock Adventures has organized trekking trips and peak climbing for me and all of them have been of a very high standard at very reasonable prices. The personal service provided is first class, communication is quick and efficient with no language barriers and the whole team go out of their way to meet our needs. Our mountaineering leaders (and guides) have always been capable and professional with no major incidents on any of our climbing and treks. They have well-crafted itineraries that I shouldn't be thinking of changing, but nevertheless, they are always ready to customize it as per my need. The Pisang Peak climbing is a great adventure, and you should definitely try it. Not to mention, they do provide you pre-climbing training which is really helpful.
