SwampLand is located underneath the bridge on Renown Road, called by the "locals" the big dipper, in Excelsior Park Baulkham Hills. To gain access to SwampLand you park in Mill Drive, on the East side of the bridge and walk down Renown Rd / Barclay Rd to the bridge. Once at the bridge jump over railing and walk underneath, SwampLand is on the other side of Darling Mills Creek just right of the bridge.
