The trip was good, although we had issues with the booking. Our booking had been taken by Viator for a Friday, but the trip did not run on a Friday. Fortunately the extremely helpful guy at the ticket office was able to rearrange for us. Good job we did not just turn up on the day.
Just a boat ride. Bare minimum in terms of guide about the area. Basically you just sit on a boat for 3 hours....
The crew gave no commentary concerning the places we were viewing from the boat as we traveled, no history and no general instructions. We arrived at the beach area and after eating we had 10 minutes before boarding the boat again, worst boat excursion we have ever done.
