Like any large city, Miami has a wealth of landmarks and happenings to explore, but visitors may not know where to start. That's where Miami Open City Tour comes in. The company rolls out spacious, double-decker buses that transport riders along two routes, allowing them to hop on and off at their leisure. As they meander through various neighborhoods, they can listen to narrated facts on provided headphones, learning about the artistry of Coconut Grove, the music of New World Symphony Center, and the plastic black and white trees of Domino Park.
