2) Is the Olympic Sculpture Park cool or weird? You are to check | The Olympic Sculpture Park is considered to be a real artwork in Seattle. The admission is free, and it’s open for visitors all year round — locals and guests of the city like to spend time here. You can wander among installations and take nice instagrammable photos. The most prominent sculptures are the Eye Benches and Seattle Cloud Cover, a glass bridge. Come to check out the place! |
3) Have a go with craft beer in Seattle | One more thing what Seattle is good at is beer. The city entered a craft beer game a long time ago, and now it’s on the latest wave. We recommend sampling some beer in Holy Mountain Brewery, though in other breweries, beer also rocks! Just taste it! |
