We just happened to stumble upon this. It is a really long trail through the ocean made of huge boulders smushed together! We walked for over and hour but didn't get all the way across. The boulders are not even or spaced evenly so in places, it was actually very difficult to cross from boulder to boulder and pretty scary. Unfortunately, I was wearing flip flops, which made it worse. If I went again, I would wear hiking boots or sneakers or something with excellent traction. There are sharks in the water but we didn't see any. We did see a couple of rats under the boulders which was terrifying, some birds, kayakers, a tall ship, parasailer and snails. If we had started earlier, we would have gone to the beach. Someone told us that if you cross the entire rock trail you end up on a grassy beach that you cross and then you can see seals and sharks and possibly whales. The views were gorgeous and the whole thing was so different than anything I have ever done. Later we read that you should check the tide before going because the water can actually come over the trail and leave you stranded! Yikes! If you have any kind of mobility issues, skip this. It is tricky in spots. I would not carry very much because even my big camera lens was cumbersome while trying to navigate these boulders and I was so scared that I would fall into the water. It was really fun though and you should put on your sneakers and do it!
