Washington Georgia City Museums Pass is the best way to see the city's wonderful museums! Purchase the pass at either Callaway Plantation at 2160 Lexington Rd, or the Washington Historical Museum at 308 E. Robert Toombs Ave. Passes are $12 each and are good for one visit to each of the city-owned museums. Once you've seen Callaway and the Historical Museum, show your pass at the Robert Toombs House Museum for $1 off admission (not included in pass price).
