The Barrel is a pet-friendly bar in boulder. The establishment is the brainchild of Ingrid and Lou Bush, a couple who've been around bars their whole lives. The Barrel is a fun and inviting place for folks to stop in for a pint or two; whether it’s after a long hike in Rocky Mountain National Park, during a shopping break or before having dinner downtown. The outdoor area is a great place to get together with friends in the Boulder sun. Dogs are welcome throughout, as no food is served on the premises. The Barrel is open Monday through Wednesday from 2pm to 10pm, Thursday to Friday from 1pm to 11pm, Saturday from 12pm to 11pm, and Sunday from 12pm to 10pm. This Boulder location is open March through October, sometimes able to stretch it to the end of November depending on the weather.
