After going back to the lighthouse & laying on a flat rock for some time like seals, we found another trail that said it was going down to some ancient pools but nobody had been taking care of the trail & it was blocked off with a gate & otherwise seemed like it had fallen into the sea & if we tried to go down it we'd also fall in. We found another trail that went to these grottoes that people evidently lived in thousands of years ago, in another time. We walked back on the same trail we were on on the day we decided to walk to the highest point on the island—the trail that had plaques of that guy that carried a cross up a hill so he could be nailed to it.
