What to see in Seattle?

Seattle must rank as one of America's hippest cities. There are so many reasons to visit this hub of creativity, enterprise, and amazing views. The list below is only the beginning:

Space Needle: Get a birds eye view of Seattle from the 'top house' of one of the most recognisable landmarks in the world. Built for the World's Fair in the 1960's the Space Needle offers panoramic views of the city and mountains beyond from over 500 feet up.

Pike Place Market: most famous as the home of the original Starbucks coffee, Pike Place Market is a large farmers market selling some of the freshest produce in the city. It is also home to some wonderful bars, restaurants, and a craft market, making it a must visit while in Seattle.

Museum of Pop Culture: From music to fashion to tattoos, this museum is anything but boring. Expect extensive exhibitions on everything from local legends Nirvana to science fiction with lots of interactivity to keep the whole family entertained.

Seattle Grunge Tour: if you are a fan of grunge music, do not miss out on a walking tour of some of the most iconic locations where your favourite musicians played, practiced, and lived.
