As everyone else has said, crowds here are the worst. Not only does it just get busy: the crowds here are particular crude, litter, loud, and generally unpleasant (drunk). Don’t go on weekends. It simply won’t be worth it. Sneak a day off and go middle of the week.

Apart from humans the park itself is a wonder. Diverse plant life, awesome views, COLD water. Be sure to take the time to explore “the castle” it is Huge and if you can make it to the top you’ll be rewarded with a view. Be careful which rocks in the water you choose to sit on in the shallow fast moving water parts, many are covered with thousands of little tiny leeches!!!
