The thermal baths at Santa Maria Coghinas, known since Roman times, feature visible thermal springs along the slow-flowing river. The water remains warm year-round. At the bottom of a granite gorge, through which the Coghinas River flows, stands the Torre dei Doria on the western side, overlooking the area.
The tower can be reached via an uphill nature trail through the Littu Park, or by parking near the dam for a shorter walk.
