I am looking for some Points for different Hiking trails in the park. Also some Kayaking points of interest that someone can point out. Thanks

The best place to start looking is at Island Packers http://www.islandpackers.com/
They are the official concessionaire gateway to the Channel Islands. They provide boat shuttle service between Ventura Harbor and the islands. Landing/camping permits and fees to go ashore are included with your shuttle ticket. They can also give you infomation about kayak rentals on Santa Cruz island during the summer months. Or you can also arrange for them to transport your own kayak. They also can give you info about maps and points of interest.

The most awesome thing that I have experienced in my visits to the Channel Island is the sensation of total isolation from civilization.
