San Francisco summers are cold, but this annual, non-commercial music festival held over three days on the first weekend of October is anything but.
Hardly Strictly Bluegrass unfurls in San Francisco's Golden Gate Park and has grown from its inception as a bluegrass-only festival in 2001 to one of the largest music festivals in the country, drawing huge crowds who come to hear more than 100 bands of all genres play across several different stages.
Bring your blankets, your best friends, your family, and your frisbees. Feel free to bring your own picnic, too, but more than 50 vendors set up in the park and sell food and drink.
Since the festival is 100 percent free, no tickets are required.
