Hi there @jimmycalabas ;) .. the trails are located north of Pasadea in the Angeles National Forest and the Mount St Antonio .. you can easily see it if you look at the map of Pasadena in the net .. It is a huuuge area and I am not sure where exactly I took the pictures .. the first two were somewhere on the trail to the top of Mount St Antonio and the second two pictures were on a trail in the Angeles National Forrest .. but there are so many trails there which all are very beautiful ;)
