A great hike if you have about a half a day to spare! Take a 10-mile hike through ocean-side cliffs, hills, and forests to Alamere Falls, a waterfall that mergers from the hills into the sea. The hike itself isn't challenging - other than for a short scramble at the end - but it is long, and one you need to start early in the day. Keep in mind that the parking lot fills up quickly, and the actual trail to the waterfall can be a little challenging to find near the end without asking fellow hikers! Travel in Spring, after the rains, for the heaviest form of the waterfall.
