You probably already know that Hawaii is home to gorgeous plants and flowers, but the Hawaii Tropical Botanical Garden is one of the more beautiful places in the entire state. At 17 acres, it’s definitely not the largest botanical garden in the world, but it’s rainforest setting makes it one of the most unique. You’ll see over 2,000 species of plants, waterfalls, creeks, and lovely views of Onomea Bay. If you visit, some must-see exhibits include the Onomea Waterfalls, the orchid garden, Lily Lake, Founders Birdhouse, and the monkeypod trees.
