North of Downtown is Lake Union, which is the site of fireworks display during the Fourth of July and is otherwise littered with yachts and sail boats the rest of the year when the sun and weather permits. You’ll find harbor restaurants, rental boat concessions, lakeside condos and office complexes, and seaplane docks around the lake.[1] The neighborhood south of the lake is known as South Lake Union. The area along the lake’s western shores is called Westlake and the area along its eastern shores is known as Eastlake. All three areas have been transformed over the past decade into a Biotechnology hub, home to cancer research centers and biotech companies.
