Trunk or Treat is a family-friendly Halloween-season event hosted by the City of Bee Cave, held at the Hill Country Galleria in Bee Cave, just outside Austin. Pull on your costume and head out for a sweet, spooky morning of candy collecting. The fun happens along Hill Country Boulevard, where you can walk the route to grab your fair share of treats. It's free, it's all ages, and it's held alongside the Rolling Sculpture Car Show, so you can check out the classic cars too.
