As well on Tuesday, we trekked through a national park for a bit over a kilometre to visit Bourna Island, shown here. The cold currents batter the island rather a bit, so we weren't able to do a lap around it. As well, some rather large jellyfish were visiting the area and my budgie-smugglers seemed a very chancy protection against them. Notably, I did see a tuna that must have followed the cool currents. As well, Jenny and I examined the small cave on the island, close to the isthmus that connects it to the mainland.
