Rincon de la Vieja Volcano
National Park

Hystorical Background
The Rincon de la Vieja National Park was created by
law No. 5398 on October 23, 1973.
Located in the Guanacaste and Alajuela provinces,
it covers a little over 14,083.9 hectares. With an
annual average temperature of 26ºC and annual
rainfall average of 2000 mm.
Rincon de la Vieja is one of the
protected areas within the Guanacaste Conservation
Area (ACG.), together with the Guanacaste and Santa
Rosa National Parks, Junquillal Bay Wildlife Refuge
and Horizontes Forestry Station.
To ensure the proper administrative and operational
management, Rincon de la Vieja National Park was divided
into two sectors, Las Pailas and Santa Maria.
The Las Pailas Sector owes its name to its volcanic
features, which include fumaroles, mud pots, and steam
vents.
The Santa Maria Sector, as of the end of the 19th
century up to 1973 was one of the largest haciendas
of the region. Meat and milk cattle raising used to
be the main objective at the haciendas, as well as
cultivation of coffee and sugar cane.
Ways of access
The Las Pailas Sector is located about 25 km northeast
of Liberia. Drive north on the Inter-American Highway,
5 km from Liberia to the approximately 20 km.
The Santa Maria Sector begins about
25 km from barrio La Victoria, in the town of Liberia.
Continue up the road to the community of Colonia Blanca,
and then make a left turn. A four-wheel drive vehicle
is recommended for these rough roads.
Flora and fauna
Due to the range of altitudes, rainfall and ages of
volcanic ash fields, there is a good variety of vegetative
formations on the slopes and craters of Rincon de
la Vieja.
On the highest forested slopes the trees become dwarfed,
gnarled, and covered with moss mats, which provide
arboreal soil for orchids and other epiphytes. Rincon
de la Vieja also houses a large population of Costa
Rica’s lovely national flower, the Guaria Morada
orchid (Cattleya skinerii).
Representative trees include Onion
Cordia (Cordia alliodora), Ear Pod Tree (Enterolobium
cyclocarpum), Spanish Cedar (Cedrela odorata), Naked
Indian Tree, (Bursera simarouba) and Copey, (Clusia
sp.). Common mammals include collared peccary (Tayassu
tajacu), agoutis (Dasyprocta puntacta), tayra (Eira
barbara), ninebanded armadello (Dassypus novecinctus),
white-faced monkey (Cebus capuccinus), howler monkey
(Alouatta palliata), and spider monkey (Ateles gefroyi).
The mountain is home to near three
hundred bird species, including the Crested Guan (Penelope
purpurascens), Blue-crowned Motmot (Momotus momotta),
Black-Faced Solitaire (Myadestes melanops), and the
Emerald Toucanet (Aulacorhynchus prasinus).
Geology and Hidrology
Approximately 600,000 years old, the Rincon de la
Vieja Volcano is a complex geological structure, consisting
of at least nine volcanic cones. The most active crater
is 1806 meters high; its sides are nearly vertical
and are barren of vegetation. The Santa Maria crater
is the highest, 1916 m high. It is presently inactive
and has some kind of vegetative cover. Along the southern
side of the volcano there are hot springs, mud pots,
and steam and sulphur vents found.
It is said that Rincon de la Vieja once served as
a natural lighthouse for sailors off the Pacific coast
of Costa Rica. Reliable reports from 1851 tell of
eruptions of smoke and ash; sporadic eruptions of
steam and ash were again observed between 1860 and
1863.
During the present century, occasional
eruptions of gases, ash and mud mixed with steam were
noted from 1966 up to the 70’s. During 1983-1984
the activity affected an area of 2 km to the south
and to the east of the active crater. Most recent
eruptions, in 1991, 1995 and again in 1997, caused
some damage to settlements on the Atlantic slope.
The mighty Rincon de la Vieja stands
astride the continental division, separating the Atlantic
from the Pacific watersheds in the northwest zone
of the country. Its height and location make it a
real 'water factory' one which has been lending service
for many years to the province of Guanacaste.
Here, important watersheds that supply drinking water
to the provincial capital, the city of Liberia, are
forever protected. In total, thirty-two rivers are
born on the Rincon de la Vieja flanks; among them
the Colorado, Blanco, and Ahogados Rivers.
Additionally, there are sixteen intermittent creeks
that flow only during the rainy season. Many of these
streams are tributaries of the Tempisque River, the
largest river in the province of Guanacaste.
