About
Located approximately 4 km to the northeast of Kızılcahamam town center, the Acısu Stream Valley is home to natural mineral water sources. The temperature of the water at its source ranges between 31 and 34 degrees Celsius. In the vicinity of the mineral water source, travertine formations have developed as a result of calcium carbonate deposition, creating a unique natural landscape. The area is visited for day trips, particularly for nature walks and photo safaris. Dense forest cover is especially observed in the area between Aksak and Çukurca.
