The Hole in the Wall hike is a very nice walk along the beach. The Sol Duc Falls trail hike is nice, but if you are short on time skipping this one would make sense to me. At the hole in the wall rock there are quite a few Pacific Ocean creatures. Take some time to look for them. In one photo you can see what I believe is a park service crew creating a trail to use during high tide, when the beach is impassible.
