Hikes and Trails- There are many options here and zero bad decisions on selecting your path. Enjoy the surroundings but keep a careful eye out on the ground because again this place sat on the bottom of the ocean. Fossils are literally everywhere and each one is a piece of history. You are not allowed to take them home but do take a close look and examine because it is fascinating.
