A turquoise blue river, whose colour results of mineral deposits in one stream mixing with the sulphurous water in another. There are plenty of birds and insects to see, including toucans. Do carry a rain-jacket with you and proper boots—the trail often is muddy. However, if money is no concern, they also rent rubber boot near the entrance. The trail takes about 1 hr one way. The visit of the park is only really worth it with sunshine (for the water to glow) and during the dry season. The water does not glow by itself, it is a beautiful reflection the light, like with water coming from a glacier. Note, during the dry season a day's rain is not an issue—the tropical soil stores a lot of water before it releases it.
Celeste River is a river in Tenorio Volcano National Park of Costa Rica. It is notable for its distinctive turquoise coloration. The Celeste River also borders several hot springs and has one large waterfall. It takes about an hour to hike to the waterfall from the park's entrance.
