The park is almost a million acres; it's enormous -- larger than small countries like Luxembourg. There are two entrances; most visitors go to the North entrance near Port Angeles to see mountains. If you want to see trees and beaches take the Southwest entrance at Lake Quinault instead.
I recommend the North Coast hike from La Push to Chilean Memorial. It's a multi-day hike, and you need to get a permit from the Park Service office at Lake Quinault beforehand. But it's worth it. Remember to get a copy of the tide charts so you don't get trapped by the tides.

The significance of the second link is ancient peoples further north and in other parts of the Americas don’t share this genetic link, indicating a longer timeline of human habitation in the region than previously thought.
