Fodor's Expert Review Parque Terra Nostra

These sprawling gardens date back to 1775, when Boston merchant Thomas Hickling built a summer house called Yankee Hall, planted trees brought in from North America, and constructed the thermal water pool, still a highlight of the park today. The gardens were enlarged in the mid-19th century, adding Australian King and Canary Islands palm trees and other imported species still thriving today. The garden is particularly well known for its collections of camellias, cycadales, and ferns, as well as for its thermal pool, which is an orange-brown color due to its high iron content. There are changing rooms and outdoor showers to rinse off after, but be sure to bring a towel and wear a swimsuit that you don’t mind getting stained.
