The Dieng Plateau, nestled in the highlands of Central Java, is often celebrated for its ancient Hindu temples, the oldest in Indonesia. However, to focus solely on these historical treasures is to miss a more expansive and breathtaking aspect of the region. This article is a guide to discovering the natural beauty of Dieng, a landscape of volcanic craters, serene lakes, and mystical landscapes that are just as captivating as its cultural heritage. Situated at an altitude of over 2,000 meters, Dieng offers a cool, crisp escape from the tropical heat, and its unique geothermal activity creates a world unlike any other in Indonesia. As a geologist from the Volcanology Research Center, Dr. Ahmad, noted in a report on February 15, 2025, “Dieng is a living laboratory, a place where the earth’s raw power is visible in every corner.”
One of the most remarkable natural features is the “Sikidang” Crater, an active volcanic crater that constantly spews plumes of sulfurous smoke. The landscape around the crater is otherworldly, with bubbling mud pits and the distinct smell of sulfur hanging in the air. Visitors can walk on wooden planks across the moon-like terrain, observing the earth’s raw, geothermal energy firsthand. It’s a powerful and humbling experience that highlights the dynamic nature of the region. A tourist, who shared their experience on a travel forum on March 10, 2025, described the visit as “a surreal walk on another planet.” This geothermal wonder is a key part of discovering the natural beauty of Dieng and a reminder of the plateau’s volcanic origins.
Another highlight of Dieng is its collection of multi-colored lakes. The most famous is Telaga Warna, or “Colorful Lake,” whose water changes hues from green to turquoise to yellow, depending on the sunlight and the concentration of sulfur in the water. The best way to view this phenomenon is from a viewpoint on a nearby hill, where you can see the kaleidoscope of colors laid out before you. The experience is both visually stunning and spiritually calming. According to a local tour guide, Ibu Ani, a respected figure in the community, the lakes are considered sacred, and “each color has a spiritual meaning.” This adds a layer of mysticism to the already enchanting scenery. The vibrant hues of Telaga Warna are a perfect example of discovering the natural beauty that the plateau is known for.
In addition to its craters and lakes, Dieng is also a perfect destination for those who love hiking and fresh air. The plateau is dotted with lush fields of carrots and potatoes, cultivated by local farmers who have adapted to the challenging mountainous terrain. The sunrise from Bukit Sikunir, often referred to as “the Golden Sunrise,” is a famous attraction. The trek to the summit begins in the pre-dawn hours and is rewarded with a panoramic view of the sun rising over a sea of clouds, with the silhouettes of Mount Sumbing and Mount Sindoro in the distance. This vista, a perfect end to a journey of exploration, is the final piece of discovering the natural beauty that makes Dieng a truly unforgettable destination.
