We knew it was a popular festival and that it was going to be crowded. So we set out early from our guest house near Oristano for the 45 minute drive to Sedilo. Even so, it was already filling up when we got there. We got as close as we could to drop off the members of our party less able to hike from remote parking. But that hike for the rest of us was pleasant for the scenery and people watching. When we got to the Sanctuario di San Costantino the hillside sloping down from the imposing cross was well populated, as were the walls and other choice seating areas. Our group congregated just inside the main gate where we saw a wide variety of local officials, Sardinian natives and more than a smattering of tourists.
