Tenorio Volcano National Park is a protected area located in the Guanacaste province of Costa Rica, encompassing the Tenorio Volcano and its surrounding rainforest.

Visual Characteristics

The park features a dormant stratovolcano with an elevation of 1,916 meters (6,286 feet). The landscape is characterized by dense tropical rainforest, with a significant portion covered by primary forest. Rivers and streams, including the notable Río Celeste, flow through the park, exhibiting a distinct turquoise coloration due to the presence of specific minerals. The terrain is varied, with steep slopes and volcanic soil.

Location & Access Logistics

The park is situated approximately 25 kilometers (15.5 miles) south of the town of Bijagua. Access is primarily via unpaved roads. From Bijagua, take the road towards San Rafael and follow signs for the park entrance. The drive from Bijagua takes approximately 45 minutes to 1 hour. Parking is available at the main entrance. Public transport options are limited; local buses may reach Bijagua, from where a taxi or pre-arranged transport is necessary to reach the park entrance.

Historical & Ecological Origin

Tenorio Volcano is part of the Guanacaste Volcanic Range, formed by tectonic activity. Its last eruption is estimated to have occurred approximately 20,000 years ago. The park protects a significant area of tropical wet forest and cloud forest ecosystems, supporting a diverse range of flora and fauna.

Key Highlights & Activities

Hiking is the primary activity. The main trail leads to the Río Celeste waterfall and the "Teñideros," where the river's unique color is formed. Other trails explore the rainforest, offering opportunities for wildlife observation. Swimming is prohibited in the river and waterfalls within the park boundaries.

Infrastructure & Amenities

Basic facilities are available at the park entrance, including restrooms and a small visitor center. There are no food vendors within the park; visitors should bring their own provisions. Cell phone signal is intermittent to non-existent within the park's interior.

Best Time to Visit

The best time of day for photography, particularly of the Río Celeste, is between 10:00 AM and 2:00 PM when sunlight is most direct. The dry season, from December to April, generally offers more favorable weather conditions with less rainfall. The wet season, from May to November, can result in muddy trails and reduced visibility.

Facts & Legends

The striking turquoise color of the Río Celeste is attributed to a chemical reaction between volcanic minerals, specifically sulfur and calcium carbonate, which causes light to scatter in a way that produces the vibrant hue. Local folklore suggests the river's color is the result of God painting the sky into the water.
