Map of Alcântara

An hour long boat ride from São Luís, two boats in the morning, returning in the afternoon.

• Ruins of church and other buildings.
• Museum devoted to rocket launching site located at military base near Alcântara.
• Igreja Matriz de São Matias. 
• Pelourinho of Alcântara. The old slave whipping post; it's the oldest extant one in Brazil. 

Reportedly there is some scattered nightlife here Thursdays through Sundays, then completely dead the next three days.
