All up and down the Miami Beach and South Beach areas is an exceptional paved path and boardwalk. Consider it your “wheelchair highway” while you are visiting Miami.
During my most recent visit (March 2019) I made sure I would cut over to the beach pathway every time I needed to move north or south along the beaches. There are no stop signs, no lights, and it’s not overloaded with people.
I used the path to get from the hotel to South Pointe Park and back in much less time than taking the roads. Of course if you haven’t gotten to see the art deco hotels and things along the street, you’re going to want to do that first!
The path felt safe even at night as it is well-lit and people meander along it at all times.
I highlighted the area in yellow on the map. I’ve taken it as far north as Indian Beach park where I believe it stops.
