There are mandatory bag checks at the entrance. Single-use plastic bottles, plastic ponchos, drones, alcohol, cigarettes, and knives will be confiscated.

Tenorio Volcano National Park operates on a strict daily schedule to ensure all visitors are off the trails before dark.
Arriving right at 8:00 AM is highly recommended to beat the large tour buses that usually show up around 9:00 AM.
Rio Celeste is located in the northern lowlands, about 75 km (a 90-minute drive) from La Fortuna.

Facilities inside the national park are minimal to protect the environment, so come prepared.
Park rangers strictly enforce rules to protect the fragile volcanic ecosystem and visitor safety.
The bright blue color is actually an optical illusion caused by a phenomenon called Mie scattering. When the clear waters of the Buenavista River and Sour Creek merge, suspended minerals containing aluminum, silicon, and oxygen reflect sunlight, making the water appear vividly turquoise.
No, swimming is strictly prohibited anywhere inside Tenorio Volcano National Park to protect the delicate mineral balance and keep visitors safe from boiling volcanic vents. However, you can swim at a free public spot located about 1 kilometer past the park entrance.
The hike is considered moderately challenging. The main in-and-out trail is about 3.7 miles long and takes roughly 3 hours. Reaching the waterfall viewing platform requires walking down and back up 250 steep steps, and the trails can get very muddy and slippery with exposed roots.

It depends on the tour. Most full-day guided tours from La Fortuna include the $12 USD park entrance fee in their price. However, if you book a self-guided ticket service or an ATV tour outside the park, you will need to verify if park entry is covered.
Heavy rainfall can wash mud and sediment into the river, temporarily turning the famous blue water brown. If you are visiting during the rainy season (especially October or November), it is best to check the park's recent conditions before going.
You must wear sturdy, closed-toe shoes like hiking boots or trail runners; park rangers will not let you in wearing sandals. Lightweight, moisture-wicking clothing and a reusable, breathable rain jacket are also highly recommended.
No, drones are strictly prohibited inside Tenorio Volcano National Park. Park rangers conduct bag checks at the entrance and will confiscate drones, along with single-use plastics and cigarettes.
A 4x4 is not strictly necessary because the main road leading from La Fortuna to the park entrance via Bijagua is fully paved. However, a high-clearance SUV is recommended if you plan to explore secondary gravel roads in the area.
As of early 2026, the lowest portion of the staircase and the bottom viewing platform remain closed due to previous storm damage. You can still walk partway down the 250 steps to get an excellent view and photos of the waterfall.
