Río Celeste (Tenorio Volcano NP)

Río Celeste gets its sky-blue color from a natural chemical reaction where two rivers meet. The hike to the waterfall, the “teñidores” and the hot pools takes 3–4 hours. Most people visit from Bijagua (paved approach) or as a day trip from La Fortuna (gravel approach via Guatuso).

About Río Celeste

Río Celeste is a river in Tenorio Volcano National Park that turns a startling sky-blue where two streams meet and minerals reflect the light. The main trail leads to the blue waterfall, a lookout, the blue lagoon and the “Teñideros” where the color appears. It’s about 1.5–2 hours from La Fortuna and 1.5 hours from Liberia.

Visiting the park

• The main trail is roughly 6 km round trip, with steep stairs down to the waterfall and muddy sections most of the year. Wear shoes with grip.
• Entrance is around US$12–15 per adult; check the official SINAC site for tickets and opening hours.
• Swimming in the river is not allowed inside the park.
• After heavy rain the water turns brown and loses its color. Sunny, dry periods give the best blue.

Where to stay

Most people visit as a day trip from La Fortuna or on the way between Arenal and Guanacaste. If you stay, the area around Bijagua has small lodges, roughly US$60–150, and quiet countryside.

Practical tips

• Arrive early: the park limits daily visitors and the trail gets busy by late morning.
• Use the official parking at the entrance or the guarded lots of nearby restaurants.
• Bring water, a rain jacket and a change of clothes for the drive back.
