Lake Union, Freshwater lake in Seattle, United States
Lake Union is a freshwater lake at the heart of Seattle, spanning several hundred acres and connecting Lake Washington to Puget Sound via the Lake Washington Ship Canal. The water is surrounded by residential neighborhoods, parks, and boathouses, serving as a central hub for water recreation and visitors.
The lake was named in 1854 by Thomas Mercer, who foresaw that a future canal would connect it to Lake Washington and Puget Sound. The Lake Washington Ship Canal was later built, realizing his vision and transforming Seattle into a major shipping hub.
The Center for Wooden Boats and Museum of History & Industry preserve maritime traditions through exhibits and hands-on activities along the southern shore. These institutions show how the waterway historically shaped the city's livelihood and commerce.
You can access the water from several locations, including Lake Union Park and Gas Works Park, where kayaks and small boats can be launched. The southern shore is particularly accessible and offers easy paths to the main attractions along the water.
The water is known for its floating homes that line the shoreline, offering an unusual residential style. One of these houses was used for the 1993 film Sleepless in Seattle and remains a popular photo spot for visitors.
