Nicknamed the Grand Canyon of the Pacific, Waimea Canyon is about ten miles long and up to 3,600 feet deep. It's a great place to realize how small you and your problems actually are. There are several lookout points as you drive through the canyon. In the designated areas you have to pay for parking but once you pay for this first one, you should be golden for all other parking areas. It's a bit of a drive to get into that area, so I highly recommend bringing some sandwiches and snacks to have lunch while taking in the view.
