The view from lighthouses of the sea is often one of the most unobstructed. the Lime Kiln Lighthouse is on the west side of San Juan Island. The best sunset is to be seen from here... but I was not able to catch transport to the park at that time. Here, you overlook a major shipping lane to Canada. It is also site of a whale sanctuary because they are seen to migrate here so often. It is a popular place for Kayaks.
