Seattle's OG Fourth of July celebration is so popular that they don’t even bother putting “July” in the event name, because everybody knows what’s up. Seafair’s annual, nationally recognized fireworks show comes complete with pyrotechnics exploding up above Lake Union and “choreographed” to a very loud pre-recorded musical score. Gas Works Park is the traditional spot to watch it from, where you'll find beer gardens, scads of food vendors, live bands, and a glow-in-the-dark dance party. On the other side of the lake at Lake Union Park, you'll find a slightly more laidback vibe with food trucks, a bar, and a DJ, plus a darker sky view of the fireworks—though they'll still be choreographed to the music.
