Walk up the street from the venue to see the Ballard Locks! These locks have more boat traffic than any other lock in the U.S. (according to Wikipedia). There's also a salmon ladder and gardens to walk around.
Fresh food, beautiful flowers, and seafood everywhere! It's a Seattle classic for a reason. The water is gorgeous and there are delicious beers at Pike Brewing!
Beer, food, and a board game shop that you can "check out" board games for free.
Great trail that stretches from Ballard to Bothell (27 miles!) that's great for walking or biking. It takes you down by the water and past Fremont Brewing (recommend) and Gas Works Park.
Delicious beer! Dog friendly! Outside seating!
Yum, beer
