7. San Francisco, California
With the addition of the mainstream Outside Lands and the slightly less mainstream Treasure Island, San Francisco has put itself on the map as a music festival destination. Of course, with veterans like Hardly Strictly Bluegrass (started in 2001), Noisepop (started in 1993), and the San Francisco Jazz Festival (started in 1983), locals have been in on the secret for years.
