The Mountains of Sis ({{langx|ca|Serra de Sis}}, or {{lang|ca|Serra del Cis}}; {{langx|es|Sierra de Sis}}) is a {{convert|28|km|0|abbr=on}} long mountain range of the Pre-Pyrenees. They are located between the valleys of rivers Isábena and the Escales Reservoir, Noguera Ribagorzana, in the Ribagorza comarca, Aragon, Spain.[http://www.enciclopedia-aragonesa.com/voz.asp?voz_id=583&tipo_busqueda=1&nombre=virgen,%20sierra%20de%20la&categoria_id=4&subcategoria_id=22&conImagenes= Gran Enciclopedia Aragonesa - Sierra de Alcubierre] The ridge's highest summits are Pico de l'Amorriador (1791 m) and Puialto (1782 m). Other important summits are 1765 m high La Creu de Bonansa, 1490 m high Altaió d'Aulet and 1066 m high Tossal de Cornudella.

Geography

This mountain chain rises abruptly from a plain and looks quite impressive from certain angles, therefore in ancient geographic works this range was also referred to as "the Great Mountains of Sis" ({{langx|es|la gran sierra de Sis}}) owing to the massive appearance of its mountains, abruptly rising as mighty foothills of the Pyrenees.Diccionario Geográfico Universal dedicado a la Reina Nuestra Señora, Sociedad de Literatos, Madrid 1792

The summits of this mountain chain offer an excellent lookout point to have a view of some of the main peaks of the Pyrenees from the south, as well as of the magnificent El Turbón in the west.[http://www.madteam.net/foro/piadas/7450-sierra-de-sis-pico-de-lamorriador-1791-mts-190410.all Sierra de Sis. Pico de l´Amorriador 1791 mts] Some of the steep rocky cliffs of the range are popular with rock climbers.[http://www.clubalpinouniversitario.com/home/?q=node/610 Sierra de Sis - Ribagorza]{{dead link|date=February 2018 |bot=InternetArchiveBot |fix-attempted=yes }}

The 9th - 11th century Santa María de Obarra monastery is located at the foot of the western end of the Sierra de Sis range.[http://www.romanicoaragones.com/2-Ribagorza/990360-ObarraSMaria.htm Monasterio de Santa María de Obarra] {{in lang|es}} There are also abandoned villages and church buildings, as well as many ancient cattle farmers' buildings known as borda in the area.
