Seattle travel tips
Though Seattle is considered to be grey, colourful characters compensate for the lack of bright colours. Citizens of Seattle hate stereotypes. For example, right at the airport, you can notice rocking chairs instead of the regular ones. Streets are full of freaks, looking bodacious and eye-catching. Don’t get surprised! Just feel the vibe of this strange city deeply!
If you want to visit all the top attractions and save some money, Seattle CityPASS will come in handy. The pass gives admission to top attractions day and night. Some transportation tips, maps, and coupons are included to make your travelling experience in Seattle stress-free and most pleasant.
When the weather is sunny and it’s not a frequent occasion, by the way, it’s impossible to keep Seattleites at home. They go outside and perform different activities. The favourite place of locals is Green Lake, the freshwater lake in the centre of the city. Sunbathe, walk or ride a bicycle, all activities are possible near the lake.
