Giant Leaves in a Park

Recently, I went for a drive with my parents. After about an hour we stopped in an area with lot of greenery. We decided to explore the area and after some walking we ended up in a large park, almost the size of a forest. There was even a lake inside. There I found something very interesting. I saw these plants with huge leaves. Each leaf was larger than my whole body!
Have you seen leaves of this size? Tell me if you have!
