Not far from South Point, the most southerly tip of the Big Island and the United States, is a green sand beach, which I’ve posted about here.
The beach is 2.5 miles from the parking lot and, if you don’t want to walk, locals will drive you there ($20 is the current fee I think) in an assortment of trucks of dubious-looking pedigree. One problem with this practice is that it has generated a warren of deep, rutted routes in the sandy soil. Erosion is a problem. Sand is swept into the ocean when it rains and when the wind blows, both of which happen often and in strength.
The county is looking into ways to mitigate these problems, which could include regulating these unofficial taxis or banning them altogether. However, before anything happens, studies will be needed along with public forums to discuss the issue. These will result in an unacceptable proposal that requires further consideration. It’s entirely possible that, by the time action is taken, South Point will no longer be the most southerly tip of either the Big Island or the United States.
