The Sierra de Orihuela is a 9.4 km long limestone mountain range that looms over the city of Orihuela. Its highest peak, Peña de Orihuela, stands at 634 meters, and the range's sheer cliffs have made it a popular destination for rock climbers. Hikers venturing up Monte St. Miguel can explore the ruins of Castillo de Orihuela and enjoy panoramic views of the city below.

To see this spectacle of nature you best book a guided tour with a local provider. Nicknamed the "Horries" and known as Garaanngaddim to the local Indigenous people, are an unusual natural phenomenon where tidal flows cause waterfalls on the ebb and flow of each tide.

The Sainte-Croix Museum exhibits a wide collection of paintings and sculptures from the ancient world, as well as modern works of art. Situated on the site of the old abbey of Sainte-Croix, it features works of well-known French artists like Louis Gauffier and Jean-Paul Laurens, as well as contemporary pieces from Raymond Hains, Jacques Villeglé and others.

The Orihuela Archaeology Museum has its origins in the former Santo Domingo Museum of Antiquities, established in 1902 by Jesuit priest Julio Furgús, who donated numerous pieces. Created by the Orihuela Town Council, the museum has been housed in various locations, including the Palacio de Teodomiro, the Municipal Hospital, the Rubalcaba Palace, and since 1997, its current location at the Church of San Juan de Dios, which was built in the mid-18th century. The museum's collection features artefacts that span a broad range of periods, from the Paleolithic era to the early 19th century. The majority of the items were excavated or discovered in the town and its surrounding areas, often through the museum's own investigations. The same building also houses the Exhibition Hall, formerly the men's ward of the hospital. This spacious, rectangular room with barrel-vaulted ceilings hosts temporary exhibitions and various cultural events.
