Formed after the eruption of the mountain Prau, the Dieng Plateau is a caldera complex situated at 2,000 meters above sea level. Its location makes it one of the coolest destinations in Indonesia, and the change is easily noticeable coming from the surrounding lowlands. The major sights to visit there include a multicolored lake, a hot spring, breathtaking sceneries from the peaks and ancient Hindu temples. Different in character from the rest of Java, trekking through the lush rolling hills, passing by beautiful plantations, and breathing in the fresh air while looking at the mountains in the horizon, is one of the most fascinating journeys to be taken in the area.
