This is where the underground water resources that feed the spa are found, and protecting them was the reason the woodland was created.

In the late 19th century, as the spa grew and tourism developed, it was one of the spaces restored by Rodrigo Berquó, though less drastically than others.

Laid out in plots and terraces along shady avenues around the hospital complex, it is home to a significant range of plants and birds, just like Parque D. Carlos I.
