Panamá Viejo, a UNESCO World Heritage site, is the original settlement of Panama City, offering a glimpse into the 16th-century colonial era. Accessibility can be limited in certain areas due to the ruins. Exploring solo allows for a personalized pace, while guided tours provide deeper historical context. There are typically no seasonal restrictions, though the dry season (December to April) offers more comfortable weather. The entry fee is minimal, and a typical visit lasts around 2-3 hours. Be sure to wear comfortable shoes for walking and bring water, especially during hotter months. The site provides a fascinating look into Panama's past.
