Rio Celeste is a bright blue river and waterfall located in Tenorio National Park.
Yes, it really is that bright blue!
It is one of the most beautiful things you can experience in Costa Rica.
The waterfall is located an hour north of La Fortuna. You can drive and pay the entrance fee to enjoy the hike on your own,
You are not able to swim in the national park, but drive down the street to this bridge and you can swim.
Don't ask me the whole chemistry behind it, but in the park you can see where the rivers meet to create the bright blue color.
Don't expect to see larger animals, but you can often see frogs and cool insects.
