The Colonia del Sacramento Lighthouse, a iconic landmark within the city's UNESCO World Heritage historic quarter, offers panoramic views of the Río de la Plata and the charming old town. It is easily accessible on foot within the historic district. Visitors typically ascend independently, though it's often a highlight included in broader walking tours of Colonia. The lighthouse is generally open year-round, though hours may vary seasonally, with potential closures during adverse weather. There is a small entrance fee to climb the approximately 118 steps to the top, and a typical visit lasts between 15-30 minutes. It's highly recommended for its breathtaking vistas, particularly at sunset, and is a must-visit when exploring the historical architecture of Colonia del Sacramento.
