The botanical park is on the road going north from Teresina towards União. The zoo part of the park is fifty years behind the West with bored unhappy animals (including a blind lion) in cages and insects on pins. Happily the armadillos (tatu) are not in cages and are free to wander around the park with the visitors. Don’t swim in the lake – it is full of caimans (jacaré). The main attraction of the park is the collection of local flora.
The 100-m (312-foot) lookout tower in the middle of the bridge is accessible by elevator with 360-degree views of the city and natural surroundings beyond.
The river Poti flows into the river Parnaíba on its way to the Atlantic, 8 km north of the center. In the dry season their colour difference is very distinct, and they continue flowing side by side, even when merged into one body. There is a floating restaurant, a monument over local fishermen´s legend and boat trips are offered for R$3. The meeting is easily accessible from the city at Av. Boa Esperança.
The Albertão Stadium (aka Estádio Governador Alberto Tavares Silva) is the place to watch local football/soccer matches. The stadium has capacity for 60,000 people.
