We picked the first trip of the day and couldn't of had more of a reward for the early start to get to the harbour than being the first boat to the spot and having it all to ourselves for at least the first hour or so. We got to see quite a few turtles enjoying their natural habitat along with schools of fish, eels, rays and one of the guides even scooped up an urchin for us all to check out, well equipped and maintained boat with a fun upbeat crew and snacks and refreshments provided. Well worth it and extremely good value for money. I'd advised doing the early trip to as by the time we were leaving there were at least 3 or 4 other boats on the spot but I'm sure regardless of the time you pick the crew will ensure you have the best time
