An Extraordinary Hot Spring Sanctuary in Chile

Hidden within the native forests of Villarrica National Park near Pucón, Termas Geométricas is one of Chile's most distinctive thermal spas. Designed by renowned Chilean architect Germán del Sol, the retreat blends contemporary architecture with the natural landscape, creating a striking contrast between vibrant red timber walkways, lush temperate rainforest and steaming geothermal waters.

A network of elevated red wooden boardwalks winds through a narrow canyon, connecting 17 thermal pools fed by naturally heated mineral springs. The walkways follow the course of the Aihué Stream, while small timber changing huts with grass covered roofs blend seamlessly into the surrounding forest, creating an atmosphere that is both tranquil and deeply immersive.

Set within a landscape of waterfalls, native vegetation and rising steam, the experience is unlike a traditional hot spring resort. Rather than transforming the environment, the carefully considered design works in harmony with it, inviting visitors to move slowly through the canyon as they soak in pools of varying temperatures surrounded by nature.

Termas Geométricas is celebrated not only for its therapeutic waters but also for its award winning architecture, making it one of South America's most remarkable wellness destinations. Each place tells a unique story, beyond the postcard.

Opened in 2004, Termas Geométricas was designed by acclaimed Chilean architect Germán del Sol, whose vision was to make the natural landscape accessible while preserving its integrity. Constructed almost entirely from locally sourced timber, the network of red walkways follows the natural contours of the canyon and allows visitors to experience the thermal springs with minimal impact on the surrounding environment. Today, it is recognised as one of Chile's finest examples of architecture integrated with nature.
