Zip lines, rock walls, bike dirt-tracks, and even human versions of Hungry, Hungry, Hippos and foosball, were just a few of the activities campers joined in on Saturday, at Sierra Nevada’ Brewery’s first “Beer Camp” event of its type.

Tickets sold-out to 4,000 people, nearly all of whom showed up at some point between the noon to 8 p.m. duration, according to Dave Hermann, media manager for Sierra Nevada. He said they are referring to the event as an “epic adult day camp.”

Tickets, priced at $30, came with access to all the activities and included one free beer. Food trucks were also available for hungry campers at an additional charge.

Other activities included a dance booth where campers put on pink earphones, all linked-up to limit noise pollution, as well as a constantly-crowded for some reason game where people hit nails into logs.

Safety was also a key concern at Beer Camp. Water stations were available at several locations, as well as “zero-waste” stations, where event staff constantly gathered recyclable and compostable materials for removal and proper sorting. A first-aid station was also available with a nearby ambulance on-call.

Event staff also swarmed the exits, making sure overly-inebriated campers caught a taxi, Uber or Lyft home, or caught shuttles running throughout the day to downtown Chico or the nearby fairgrounds.
