When Mark Twain saw this park, he dubbed it the Yosemite of the Pacific. Yosemite it's not, but it is a lovely deep valley with the curious "Iao Needle," a spire that rises more than 2,000 feet from the valley floor. You can walk from the parking lot across Iao Stream and explore the thick, junglelike topography. This park has some lovely short strolls on paved paths, where you can stop and meditate by the edge of a stream or marvel at the native plants. Locals come to jump from the rocks or bridge into the stream—this isn't recommended. Mist often rises if there has been a rain, which makes being here even more magical. Parking is $5, when an attendant is present.
