The Parque D. Carlos I is a large park in the centre of town. The park contains a doughnut-shaped lake with a small island in the middle. Visitors can rent rowboats on the lake. The José Malhoa Museum sits in the middle of the park. The Jardim da Água (Water Garden) is a large-scale outdoor sculpture combining concrete, ceramic tiles, and water. Caldas has three mid-18th-century baroque fountains which were declared properties of public interest in 1982: Chafariz da Estrada da Foz (Fountain of Foz do Arelho Road), Chafariz da Rua Nova (Fountain of the New Street), and Chafariz das Cinco Bicas (Fountain of the Five Spouts).
