If there's one thing San Francisco is really good at, it's eating and drinking outdoors. Celebrating both: Beer Camp Across America, the country's largest celebration of craft beer, is coming to Pier 35 on June 18.

Presented by Sierra Nevada Brewing Co. and the San Francisco Brewers Guild, this beer festival hits the pillars of the ultimate summer festival—beer tastings included, live music, food trucks and an ideal outdoor venue. And with more than 120 breweries including Russian River Brewing Co., Ballast Point, Firestone Walker, Ninkasi Brewing, 21st Amendment and Almanac Beer Co. already signed up to pour, there will be some really good beer going around.
