Tenorio Volcano National Park was created in 1995 to protect Tenorio Volcano — one of Costa Rica’s six active volcanoes — and the four unique life zones found within the park.
Though Tenorio Volcano National Park is one of the newest national parks in Costa Rica, it is also one of the most beautiful — visitors travel far and wide to not only marvel at Tenorio Volcano but also the stunning turquoise waters of the Rio Celeste and Rio Celeste Waterfall inside the park.
If you’re planning a visit to Tenorio Volcano National Park soon — you won’t be disappointed by the beautiful trails, natural hot springs, and stunning beauty that will greet you beyond the park’s entrance!
Overview of Tenorio Volcano National Park in Costa Rica
Tenorio Volcano National Park is open from 8 AM to 4 PM daily. The final entry is at 2 PM.
Since it takes about five hours to complete the park’s single hiking trail (with stops along the way), we recommend arriving at Tenorio Volcano National Park as soon as it opens.
Additionally, despite being one of the five most-visited national parks in Costa Rica, Tenorio Volcano National Park only allows 500 tourists inside at a time and a maximum of 1,000 tourists into the park per day. Arriving early (especially during the dry season) will ensure you can enter the park.
Popular Attractions in Tenorio Volcano National Park
As the park’s name suggests, Tenorio Volcano is the main attraction at this national park. This volcano towers over 6,000 feet and is surrounded by beautiful cloud forests and rainforests. You can even see Lake Nicaragua on a clear day from the summit!
This hike will lead you past all the park’s major attractions, including Rio Celeste Waterfall and La Laguna Azul (Blue Lagoon) — a small lagoon with an intense blue color created from a high concentration of natural chemicals. At the end of the hike, you’ll also see El Teñidero, the spot where two rivers meet to form the Celeste River. At this point, the water in the river turns from clear to blue.
Rio Celeste Waterfall
Rio Celeste Waterfall is widely considered to be the most beautiful waterfall in Costa Rica, thanks to the bright blue color of the cascading falls into the pool below. This vibrant blue hue is caused when sulfur and calcium carbonate (caused by the volcanic activity from Tenorio Volcano) mix together.
You’ll pass Rio Celeste Waterfall on the main trail through Tenorio Volcano National Park. You can take a series of stairs down to the waterfall’s base (it will add about 500 feet to the hike to climb down), which we highly recommend. You can snap a photo of the stunning waterfall, but swimming at the base of the falls is prohibited.
Rio Celeste (Celeste River)
The Celeste River (or Rio Celeste) borders Tenorio Volcano National Park, making it one of the can’t-miss attractions in this national park. Although swimming in the park is not permitted, there is a swimming hole (called the “Rio Celeste Free Pool”) that is just a mile or so from the park’s entrance.
Tenorio Volcano National Park is filled with tons of bubbling mud pots, thermal geysers, and stunning natural hot springs — like La Laguna Azul — from the volcanic activity within the park.
Best Time to Visit Tenorio National Park
The best time to visit Tenorio Volcano National Park is during the dry season, from December to April.
Significant rainfall can diminish the vibrant blue hue of the waters in Tenorio Volcano National Park. Because the Rio Celeste Waterfall and the Celeste River are two of the most beautiful attractions in the park, we recommend planning your visit to the park around the rainiest months of the year — September and October — to enjoy the park to the fullest!
