I usually go to seward park during the day, there is this really nice spot in the central district that overlooks the I-90 and bellevue..... there is also a park on beacon to that over looks the city, hmm if you feel adventurous there is a spot on queen anne, which i cant seem to find when i look for it sober, but always end up there when im high out of my mind.......gas works park over looks lake union, volunteer park on capitol hill....thats just to name a few.....BUT my most favorite place to smoke in seattle is this little look out on beacon hill that gives you an amazing view of the city and sound on a clear night.
