Why live in Tumwater? Tumwater is a great middle point for Olympia and Lewis County employment centers with easy access to I-5. Tumwater is close to many State and Federal buildings, the Olympia Airport, parks, and shopping centers. Tumwater is probably most famous for being the home of the Olympia Brewery, which claimed it was the water that made its beer so good. Although the brewery closed in 2003, the Old Brewery still stands along the Deschutes River. You can walk along the river and enjoy the Tumwater (0 comments)
