Through the end of August, you can tour the Alki Point Lighthouse on Saturday and Sunday afternoons, free, courtesy of the U.S. Coast Guard Auxiliary. (Their infopage even reveals a gift shop!) Full details here; also hat tip to Puget Sound Maritime and to a wall note on Facebook (find us there at facebook.com/westseattleblog) from Stacy, who toured on the 4th and called it “awesome.”
