Food to try

• Empanadas Pampeanas — Hand-held pastries filled with ground beef, onions, and spices, often sold by local vendors near the lagoon entrance and perfect for a portable snack.
• Asado Criollo — Traditional Argentine grilled meat featuring beef, chorizo, and offal cooked over open flames at picnic sites, typically shared family-style with fresh bread and chimichurri.
• Locro Puntano — A hearty regional stew from San Luis combining corn, beans, meat, and squash, served as a warming main course at local restaurants near the park entrance.
• Fresh Trout from Local Sources — Freshly caught or farmed trout from the lagoon, often prepared simply grilled or baked, representing the aquatic resources of the area.
• Dulce de Leche with Outdoor Tea Service — Homemade sweet caramel spread paired with mate or hot tea, enjoyed during afternoon breaks on the shore as a typical Argentine tradition.

Local customs & good to know

• Respect Protected Natural Area Rules — The lagoon and surrounding lands are protected; visitors should stay on marked trails, avoid removing flora or fauna, and follow posted regulations to preserve the ecosystem.
• Arrive Early for Best Experience — Potrero de los Funes is busiest on weekends and holidays, so arriving in early morning hours provides quieter nature access and cooler temperatures for hiking.
• Mate Sharing Etiquette — If offered mate (a communal herbal tea) by locals or fellow visitors, accept it graciously, drink from the shared straw, and pass it back with both hands as a sign of respect.
• Sun Protection Essential — The high-altitude Pampean sun is intense; bring sunscreen, hats, and extra water as shade is limited on open lagoon trails and dehydration is a real concern.
