Parque Arqueológico San Andrés, a significant Mayan archaeological site in El Salvador, offers an enriching historical experience. It is best accessed by car, though public transport options might require transfers; the site paths are generally navigable but may present minor accessibility challenges for wheelchairs. Visitors can explore independently, but hiring a local guide (available on-site for an extra fee) is highly recommended for deeper historical context. The dry season (November to April) is ideal, as the rainy season (May to October) can make paths muddy, though the site remains open year-round. Expect an entrance fee of approximately $3-$5 USD for foreigners, and plan for a typical visit duration of 1.5 to 3 hours, which includes exploring the pyramids, administrative structures, and the on-site museum. Don't forget water, sun protection, and comfortable shoes for walking around the ancient city.
