Wednesday, 10 April 2024 - Visited the Sillar Route quarries at the base of Chachani Volcano, exploring hand-hewn blocks and seeing makeshift chapels, hiked through the Culebrillas Canyon to view petroglyphs, then spent the afternoon exploring Arequipa's main square, Basilica Cathedral, Church of the Company, and other historic sites, admiring frescoes, carved pulpits, and gold and silver details.
