Aek Rangat Pangururan, also known as the Pangururan Hot Spring, is a renowned natural attraction located on the slopes of Mount Pusuk Buhit in Siogung Ogung Village, Pangururan District, Samosir Regency, North Sumatra. The hot spring originates from geothermal activity associated with the Toba caldera, resulting in sulfur-rich waters believed to offer therapeutic benefits, particularly for skin conditions. The water’s temperature is naturally high, so it is mixed with fresh water to achieve comfortable bathing temperatures.
Aek Rangat is surrounded by striking white sulfuric rocks, creating a unique and picturesque environment. The area offers serene views of Lake Toba and the surrounding hills, providing a tranquil setting for relaxation.
Aek Rangat is approximately a 10–15 minute drive from Pangururan town center. For those traveling from Medan, the journey involves a ferry crossing to Samosir Island, followed by a drive to the hot spring location. A visit to Aek Rangat Pangururan offers a blend of natural beauty, cultural significance, and relaxation, making it a must-visit destination on Samosir Island.
