  • “Islay” comes from the Salinan word Yslay or Slay meaning wild cherry or chokecherry – used by the Chumash.

  • Islay Hill is the southern most Morro of the series of nine. The Morros consist of nine peaks located in San Luis Obispo County. The nine are made up of volcanic intrusive rocks. That is, rocks which meddled into a previously existing set of unrelated rocks, broke through and pushed them aside. With subsequent erosion, the peaks which are so prominent in the area today were formed.

  • There is a 400 foot altitude gain.
