Haggling is uncommon in most markets; prices are usually fixed, but polite negotiation for larger purchases or artisan goods may be acceptable.

Public buses are affordable but often crowded and informal; pay in cash directly to the driver or helper, and keep belongings secure.

Try 'pupusas revueltas' (stuffed corn tortillas with beans, cheese, and pork) and 'yuca frita con chicharrón' (fried cassava with pork), which are beloved local specialties.

A handshake or a light cheek kiss (one or two) is common among acquaintances, while a simple 'buenos días' or 'buenas tardes' suffices for strangers.

Plan around August's 'Fiestas Agostinas,' a month-long celebration with parades, food, and music, or Semana Santa (Holy Week) for elaborate religious processions.

Visit less-crowded beaches like El Cuco or El Tunco, avoid littering, and support local beachside businesses that prioritize eco-friendly practices.
