While the Sacred Valley in Peru is generally safe due to its popularity among international tourists, it is always recommended to exercise caution while walking alone at night. As darkness falls, navigating the uneven streets can become a challenge, amplifying vulnerabilities to personal accidents. Additionally, basic safety measures suggest not venturing into less-traveled paths alone after daylight hours. Hence, it is recommended that solo female travelers take taxis during late hours, preferably from a trusted company. Overall, maintaining vigilance and adhering to good safety practices will ensure a memorable travel experience.
