This is quite a hike, so wear good shoes and bring water. They have recently opened a visitor's center that is a beautiful building, but can only be accessed with the price of admission. You can save yourself a few dollars by just walking down to the Causeway on your own. It is amazing to see what nature has done in this interesting display of rock formations. Make sure you know some history on the site before you go, so you can truly appreciate what you are seeing.
