When I was last time in Miami, 12 y ago, I was advised strictly not to go to Little Haiti. It was a dangerous neighborhood with a high crime rate.
This time I put it on my list, as I read about it becoming a hip area with local culture. It was also on our way as it's just little bit north from the magnificent Wynwood which was planned for that day.
Unfortunately, we wasted our time. Apart from few murals and graphiti (which looked underwhelming after the Wynwood) everything else was quite ordinary and pretty much waste of time.
So, save your time and gas for future, maybe it will become new Wynwood some day.
