Points of interest

The only designated natural park in the region of La Rioja, the Sierra de Cebollera Natural Park is located on the northern slope of the mountains of the Iberian System about 50 kilometres from Logroño. It is also part of the Sierras de Demanda, Urbión, Cebollera and Cameros special protection areas for birdlife (Zonas de Especial Protección para las Aves (ZEPA)

The backdrop of the Sierra de Cebollera Natural Park is its smooth, rounded mountain terrain coupled with dense forests alternating with clearings in the higher areas to make room for pastures and mountain thickets.

Autumn in particular is a perfect time to visit this area as the mosaic of leaves is a fantastic sight with a whole range of warm colors from yellow to ocher and red that reveals the rich tree diversity that is camouflaged by the lush greenery of spring and summer.

La Rioja, in general and over a very long time, has suffered somewhat from the degradation of it’s forests and woodlands (basically holm oaks) caused mainly by logging and sheep (over) grazing.

However, there still remains a long list of plantilfe such as Brachypodium retusum, Helichrysum italicum, Helichrysum stoechas, Lavandula latifolia, Lavandula stoechas, Lonicera etrusca, Pistacia lentiscus, Pistacia terebinthus, Quercus coccifera, Retama sphaerocarpa, Rosmarinus officinalis, Salsola vermiculata, Santolina chamaecyparissus and Thymus mastichina.

The richest riverside forests are those of the Ebro river (Reserva Natural de los Sotos del Ebro). As the riverside forests are humid and fertile, they have been largely occupied by agriculture but wild areas still remain with Cornus sanguinea, Crataegus monogyna, Euonymus europaeus, Fraxinus angustifolia, Humulus lupulus, Populus alba, Populus nigra and Rubus ulmifolius, Sambucus ebulus, Ulmus minor, Urtica dioica and Vitis sylvestris.

There are two types of holm oak groves in La Rioja according to the type of soil. The first is limestone, in which, for example, boxwood and strawberry trees appear (Montes Obarenes and Sierra de Toloño) and the siliceous soils in which heather, acidophilic rockrose and butcher’s broom appear, for example (Valle de Ocón, Monte de Ausejo, Sierra de Yerga, Carrascal de Villarroya, and Sierra de Alcarama). Here we can find Arbutus unedo, Quercus ilex spp. rotundifolia, Viburnum tinus, Rhamnus alaternus, Cistus albidus, Cistus laurifolius, Cistus salviifolius, Rhamnus licioides, Juniperus phoenicea and Juniperus oxycedrus.


The Sierra de Cebollera Natural Park also enjoys a rich fauna in which birds of prey such as the goshawk, honey buzzard, booted and short-toed eagle, common buzzard, tawny owl and long-eared owl are present. Also keep an eye open for grey partridge.

Amongst the mammal population to look out for there are fox, wild boar, red deer, red squirrel, wild cat, otter and the Pyrenean desman.
