Pike Place Market
Chihuly Garden and Glass Museum in Seattle Center, Gasworks park, bike on the Burke-Gilman Trail around Lake Washington
Ferry to and from Mariner’s game, Argosy cruise, Seattle Center. In the evening, would recommend music at Jazz Alley or the Moore theater downtown
Ferry to Bainbridge Island is a must do. Just walk on. The view of Seattle from the sound is spectacular.
Kayaking or paddleboarding at Aquaverde by the UW
