The surrounding gardens feature numerous walking trails and bird sanctuaries, offering a chance to spot vibrant tropical bird species while wandering through tropical flora. Historically, Diamond Falls has been a popular destination since the 18th century, blending natural beauty with cultural heritage, as the area once served as a mineral spa for European settlers.
