@curious_travel: The blue soil indicates the high copper sulfate contained in Sagada's hills. They said that when wet, they turn even bluer. Some tourists skip the trek to see the sea of clouds and just go directly to where the blue soil is, so they pass the other way.#bakasyonsapinas🇵🇭🇵🇭🇵🇭 #bluesoilsagada #sagada #sagadamountainprovincephilippines
