Seattle is surrounded by water on all sides. A green smudge may be seen on the city's northern outskirts, where the Montlake Cut divides Lower Montlake from the University District and Portage Bay from Union Bay. This is a remnant of a former lake that covered much of what is now downtown Seattle. The center of town is also greenswarded, but instead of seeing trees beyond it, you see skyscrapers. This is because downtown Seattle is built on piers, which are often visible beneath the surface of Lake Washington. The lake is also used for open-air concerts, with views of the skyline as a backdrop to the music. In fact, there are many picturesque spots in and around Seattle where you can enjoy the view of the city's core without having to pay for expensive tickets or food. If you're looking for a cheap vacation option then consider visiting Seattle later in the year when the crowds have gone and the weather is nice.
