Just visited this park that just reopened. A little crowded but worth the visit to view the iconic Iao Needle and some other impressive nature. You can see the Needle right from the parking lot, so if you don't want to hike, you can take it in from there. Easy hike on the footpath with a slight grade, many places where you can get to the River, lots of families/kids wading in the water. $5 for parking, a good hour or so is about all you need.
