What was once a rundown warehouse and residential district has transformed in a handful of years to the hottest neighborhood in the city. Tons of tours by bus, bike, car, and foot make their way through Wynwood's streets, but many offer scant insight into the colorful culture of art and commerce. If you really want to learn Wynwood's history and comprehend the vibrant murals, turn to the artists. Miami's Best Graffiti Guide runs a variety of daily tours led by two guys who dedicated their lives to Wynwood's art scene years before iconic developer Tony Goldman sparked the neighborhood renaissance. Ryan the Wheelbarrow of Wynwood Mural Tours began offering free bike tours every Sunday at 4 p.m. a few years ago. Local artist Pedro AMOS, who had been a graffiti artist for decades, soon started his own Wynwood tour. The two joined forces this past January, and they have more collective knowledge of this scene than the Greater Miami Convention and Visitors Bureau (with whom they work). In fact, they are the official tour guides of Wynwood Walls. Tours range in price from $20 to $100. The guides also offer paint demo events for large groups — the cost is about $1,000 for those who wish to try their hand at graffiti on practice walls. The "can control crash course" comes with snacks, beverages, and supplies.
