Mirador Ullúm overlooks the Ullúm reservoir and the road-and-water landscape near the Dique. Photograph layered shorelines, winding inlets, and wide sky reflections—especially with dramatic clouds. Best light is sunrise or late afternoon; mornings are calmer for water texture and fewer crowds. Accessible by car; park at/near the mirador area and expect local road conditions typical of regional San Juan.
