For bird's-eye views of the theatre – and phenomenal vistas of Mont Ventoux and the Dentelles de Montmirail – follow montée Philbert de Chalons or montée Lambert up Colline St-Eutrope (St Eutrope Hill; elevation 97m), once the Romans' lookout point. En route, pass ruins of a 12th-century château , once the residence of the princes of Orange.
