This 63-acre site is where visitors get the chance to learn pretty much everything there is to know about the history, nature, and culture of Marathon and surrounding areas. The site itself is quite spectacular, with tropical plants, nature trails, and educational exhibits scattered about. The expertly-restored home of pioneer George Afferley still stands on the site and is open to visitors who wish to learn more about him and his contributions to the area. Guests can also take a trolley tour around the botanic gardens and various historical sites around the grounds.
