Tenorio National Park is best known for the beautiful
Rio Celeste, whose light blue waters are caused by the emanation of sulfur
and the precipitation of calcium carbonates.
Tenorio National Park can be reached by several routes. See Driving Map below.
From San Jose, take
the main highway to Ciudad Quesada (aka San Carlos), then to Upala. Turn
left in Upala towards Bijagua, and follow the road approximately 30 miles
to the entrance of the Park.
Alternatively, from San Jose take the Interamerican Highway to Cañas.
About 6 miles after Cañas is a turnoff to Bijagua. About 20 miles
past Bijagua, you will find the entrance to the Park.
