Battery Point Lighthouse in Crescent City, California is well worth a visit! The lighthouse is actually on a small island just offshore. The lighthouse is only open (during season) when the tide permits folks to “walk” over. On our first visit we actually missed it, but fortunately there are so many other scenic sites in the area, that we had no problem returning later in the day.
