San Agustín Archaeological Park, a UNESCO World Heritage site in Colombia, is best explored over 3-4 hours to see its main archaeological sites, though a full day or two is recommended to visit nearby related areas like Alto de los Ídolos and La Chaquira. While accessible via generally well-maintained but sometimes uphill and uneven paths (not fully wheelchair accessible), a guided visit is highly recommended to fully appreciate the complex history and significance of its monumental pre-Columbian sculptures; solo visits are possible with information boards. The park is open year-round, though the rainy seasons (April-May, October-November) might result in muddy paths. Expect an approximate entrance cost of around 50,000 COP for foreigners, with additional costs for local guides (typically 50,000-100,000 COP) and local transport. Visitors should wear comfortable walking shoes, bring water, and prepare for varying weather conditions with sun protection and rain gear.
