Miami-Dade Transit's Route B is a study in contrasts. Originating downtown, your bus soon offers a postcard view of the concrete jungle you left behind and of the Brickell skyline as it crosses the Rickenbacker Causeway on the way to the manicured municipality of Key Biscayne. This trip affords access to several of Miami's prime recreation locales. You can hop off to visit Virginia Key's sandy coves or Seaquarium; the golf course, tennis courts, and beach of Crandon Park; or stay to the end of the line to reach Bill Baggs Cape Florida State Park (for the park, the bus sign must indicate "Key Biscayne by Way of Crandon Boulevard"). By taking public transport you also save on the Bill Baggs admission fee.
