Important centre of the Sirente -Velino Park is the ancient Obinolum primitive settlement of the Marsi, in a dominant position on the southern edge of the Altopiano delle Rocche plateau. The stronghold was destroyed during the social war that saw the Italic populations unite against Rome in 90 B.C. and was later rebuilt by the Lombards. In 1223, Tommaso, Count of Celano, took refuge there during his rebellion against Frederick II. In 1463, Ovindoli became a fief of Antonio Piccolomini, and until 1806 it belonged to the County of Celano. The town retains some artistic and historical interest from the past. From the Marsica side, it is the natural gateway to the vast Karst plateau of the Rocche, enclosed between the Velino and Sirente massifs. It is a well-equipped summer resort and winter sports centre including La Magnola, with ski fields well equipped with modern sports facilities. In the winter period, the centre also offers the possibility of cross-country skiing, alpine skiing and hiking. In the summer period, numerous leisure opportunities are offered to tourists: hiking and horse-riding trails, mountain bike trails, paragliding, archery and free climbing.
