Visitors can easily enjoy it solo or as part of a wider walking tour of the city, with a typical visit lasting 5-15 minutes for photos and admiration. There are no seasonal restrictions, though early mornings or late afternoons are ideal for photography to capture the arch, often with Volcán de Agua in the background, with fewer crowds and better light.
