If you have been before - you then MUST know - that your choices are very limited.
You can walk all the place twice even thrice in an hour.
Maybe four - at the most six pubs.
Maybe walk out on the jetty and watch the people harassing the dolphin...by the bay entrance.
Good for photography and sometimes some large minus tides. Get up at dawn and walk the area for 5 to 10K around the bay - your time will be best spent that way. Watch the fishing boats unload.
Sincerely,
