Avery is a CDP, not a town in the city-hall sense. Population 636, ZIP 95224, named after George J. Avery, the first postmaster (post office opened 1885). It's the last named stop before you hit Arnold, which is why old marketing copy calls it the gateway to Calaveras Big Trees. Locals just call it the stretch with the hotel and the skull bar. There are a few more reasons to know it than that, though.
The Historic Avery Hotel started life as a family home in 1851, became a hotel in 1853 under Peter and Nancy Avery, and was known for decades as the Half Way House because it sat midway between the Murphys gold fields and the giant sequoias. The Gotelli family bought it in 1992 and renovated heavily. Today it sleeps 23+ overnight and handles events up to 150, with two bars, a billiards room, a formal dining room, and a wood stage. Call (209) 517-2465 to check what's on the calendar before you assume anything.
Howard's Mystic Saloon at 4529 CA-4 is the other anchor. Curt and Tana Howard lease the old Avery Saloon building and run it in a black goth / mystic style year-round, not just at Halloween. Skull chandeliers, themed decor, table shuffleboard, pool tables, a juke box, and occasional live music. Drinks only, no food. Worth a stop and a drink for the vibe. People behind the bar are friendlier than the decor suggests, and it photographs better than any other bar on the corridor.
Two more things people miss about Avery. Day-O Espresso at 68 Avery Hotel Rd is a drive-thru coffee hut where the fancy toasts are the real move (cinnamon toast on thick bread). And JC Power Equipment, opened January 2019 by Jim and Nancy Conway, is the small-engine repair shop the whole corridor relies on for weed eaters, snowblowers, generators, and chainsaws. They also sell ethanol-free fuel. When the power went out the first time, Jim said, people were lined up.
