The G 503E trail is a short link that connects the G 503 D trail and the G 504 trail. It begins in the locality of S'ena 'e lottori, where it branches off from the G 503 D trail taking an east direction, to rejoin the G 504 trail.
About 220 meters from the start of the trail there is a monumental holm oak which is interesting both for its size, and because it grew among the granites; from here the trail continues up to the G 504 trail which leads to the Pattada area.
