This is a must do on Maui. And, it's a State park so all you pay is $5.00 for parking. It is so beautiful and there are great paved walk ways and stairs so it's very easy to enjoy the whole park. It isn't very large but there are a lot of different areas to explore and get away from the main crowd. There's a beautiful stream that runs through and has such a calming effect. A lot of people have late flights out of Maui and this is a great thing to do on that last day when you can't go to the beach because you've already checked out of your lodgings. It's only one town away from the airport and an easy drive over to Kahulua. We spent a few hours there before going to dinner and then to the airport.
