Just a five-minute walk down stairs from Pike Place Market is the Seattle Waterfront. The Waterfront showcases The Seattle Aquarium, Seattle Great Wheel, The Crab Pot and more. While at the Waterfront you can watch people fish off of Pier 57 or feed the birds that ask for bread.
Also located at Pier 57 is the Great Wheel, which only costs $12 for people 12 and up. Once you tire of the Waterfront, you can go to Pier 52 and take a ferry across Puget Sound for a new adventure in Bainbridge Island or Bremerton.
