Go to a state or national park. For free.
Spend Martin Luther King day at any of our 140 state parks or one of Washington's national parks, including Olympic National Park, which just so happens to be the 12th best in the country. Allegedly.
Fisher Pavilion at Seattle Center
Belgianfest is back at Seattle Center, and that means over 100 beers brewed in Washington using yeast from Belgium. Sample styles like dubbels, tripels, saisons, abbeys, and lambics. The brewers list is TBD at the moment, but food vendors include Dante's Inferno Dogs, Daddy's Doughnuts, and Brewmasters Bakery.
Cost: $37 advance and $45 at the door (includes tasting glass and 10 tasting tokens)
This incredibly creative "food incubator" is always hosting interesting dinners inspired by everything from the seasons to video games, like this iteration of 1985's Oregon Trail, so you better hope they did enough hunting to make all 7 courses, and packed enough wagon wheels, obviously.
This "brief" fun run is only a mile or so, and takes place in the middle of a big party to raise money for charity. The only catch is that runners go in their undies, which means you've got a lot of additional running to do between now and then to get ready.
Pike Brewing Company
Over 50 breweries, wineries, distilleries, restaurants, cheese makers, bakers & chocolatiers are posting up at Pike Chocofest, which'll feature rare beers, and all kinds of food, made with -- or made to go with -- everyone's favorite ingredient: chocolate.
Cost: Around $60, and that includes 10 drink tickets and unlimited bites
