If you feel like doing a fun easy hike and swimming in a beautiful lake in the mountains right outside of Seattle. This is about a 30 minute drive and well worth it if you have time to kill.
If you like dumplings, you have to go here. So good!
Includes admission to 5 attractions, including: Space Needle Seattle Aquarium Chihuly Garden and Glass Argosy Cruises Harbor Tour Museum of Pop Culture (MOPOP) Woodland Park Zoo Pacific Science Center
Always a fun place to watch the boats.
Classic Seattle experience and a cool way to learn about the area
Amazing rooftop bar with a "secret" entrance in South Lake area. Great food as well
They have a few locations and have really good Pho, among other things.
Hop a ferry to Bainbridge Island and walk around in the cute little town just across Elliot Bay. You can walk from the ferry terminal and there are lots of shops and restaurants and a few tasting rooms.
