Explore Miami
There’s nothing quite like stepping out of the airport to be greeted by the welcoming signs of paradise: palm trees, sand, and sun. Take the Metrobus, the Metrorail or Tri-Rail, or pick up a rental car when you deplane at Miami International Airport and let your oceanside adventure begin.
Thanks to the Gulf Stream, Miami stays warm all year long—swimsuits are a must! Choosing where to plant your beach umbrella can be overwhelming; try starting with Lummus Park. This popular South Beach spot offers relaxation, sports, and everything in between. If you’re traveling with kids, there are two playgrounds from which to choose. Outdoor gyms and volleyball courts invite visitors to get their heart rates up, but beach access from the park calls you to lay out and dig your toes into the warm sand. Once you’ve had your fill of sand and sun, it’s time for a stroll down Ocean Drive. This world-famous strip of Art Deco hotels and celebrity-run eateries has been featured in countless TV shows and movies. Once you see if for yourself, you’ll understand why!
