Tenorio Volcano National Park
The Tenorio Volcano National Park shelters plant species like orchids, bromeliads and ferns, a variety of trees, and natural hot springs. One of its unique attractions is the famous Sky Blue River (Rio Celeste), acclaimed for its sky blue colouring that results from the many minerals mixing in its waters.
The Rio Celeste is one of Costa Rica’s most spectacular rivers for its unique sky blue colouring. In the shadow of the Tenorio Volcano, an hour northwest of La Fortuna and Volcano Arenal, the Celeste River is a must-see attraction. At the confluence of two rivers, the Celeste River appears a bright sky blue to the human eye (and cameras) from volcanic minerals in the water reflecting the sunlight. There is a beautiful waterfall and also natural thermal springs in the area. Trails lead you through picturesque forest to the river.
