The tourist information office is actually outside of the centre, which is both rather odd and makes it a little difficult to find. Visitors naturally gravitate to the town side of Cathedral Hill as this is where the buses and ferry stop and where you'll find car parking. The tourist office, rather unhelpfully, is right on the other side of the hill in the administration building of the local government. Oh, and when we went there the first time there was a sign 'Back in a moment' in the window of the locked door.
