From the bowels of the ship to the bridge, the hard hat tour ($30) was far better than a self guided tour ($12). The docents were outstanding and explained the unique features of the ship, going places not open to the public. Lots of steep ladders (where the hard hats are needed). It is a miracle that this ship is still around despite years of neglect. This is the only WW1 dreadnaught left on the topside of water. Finding it is easy if you can follow signs, but beware the police car waiting for speeders on the long approach.
