In San Isidro is Huaca Huallamarca (also called Pan de Azúcar, or "Sugar Loaf"), at the corner of Av. Nicolás de Rivera and Av. El Rosario. The perhaps overzealously restored adobe temple of the Maranga Lima culture has several platforms and is frequently illuminated for special presentations. It's open Tuesday through Sunday from 9am to 5pm; admission is S/5 for adults and S/3 for students.
