Crowning the summit of Monte Bà rbaro, this 3rd-century BC Greek theatre is Segesta’s most prominent ruin after its famous Doric temple. The theatre commands sweeping views north to the Golfo di Castellammare (with a rather incongruous-looking modern autostrada snaking its way across the valley in the foreground). A shuttle bus (€1.50, half-hourly) climbs to the theatre along the 1.25km access road from Segesta’s ticket booth. Return via a lovely 30-minute downhill footpath with wonderful temple views.
