There are several impressively massive, hundreds-of-years-old trees, accessible on short walks down well-labelled side trails off of the main road, and one halfway along the longer Crocodile Lake trail. The tung tree on the Crocodile Lake trail is the most massive (if hiking solo at a non-busy time, you may regret not having anyone to take your picture with it), though the tung tree on the short three-tree trail closer to park headquarters comes in a respectable second place. The "six-rooted intersecting ficus", down a short trail about halfway between headquarters and the Crocodile Lake trailhead, is maybe the most interesting. Smaller but still quite big and tall trees are common in parts of the forest, especially the stretch of dirt road just beyond Heaven's Rapids.
