The Gorge Amphitheatre, Open-air amphitheater in Grant County, Washington, United States

The Gorge Amphitheatre is an open-air theater and music venue in Grant County, Washington, United States, set on a cliff above the Columbia River that uses a natural slope to hold thousands of spectators. The seating is arranged in terraces that face a large stage set against the river landscape.

The site was created in 1986 when the Bryan family converted their winery into a concert space and gave it the name Champs de Brionne Music Theatre. Over the following decades the operator changed hands several times, and the current name became established later.

The grounds take their name from the river gorge and were built on the Bryan family's vineyard land. Today the site is especially known for multi-day music events, where visitors often camp nearby for several nights and experience concerts as a communal gathering.

Visitors should plan for all weather conditions, as the site offers little shade and can become cool in the evening. Camping areas are within walking distance and are supported by shuttle connections during larger events.

The land was bought in 1979 by neurosurgeon Vince Bryan Jr. and his wife Carol, who planned a winery and found a canyon-edge spot resembling an amphitheatre while hiking with friends. Their first wooden stage went up in 1984, and a Wenatchee Dixieland jazz band played to over 1,000 guests. The winery, Cave B Estate, stayed with the family after the 1993 sale.
