The Tenorio Volcano National Park is in the Guanacaste province of Costa Rica and home to the beautiful Rio Celeste.
To get to Rio Celeste it is about a one-hour bus trip from the town of Guatuso and a 3-km hike.
Minerals from the volcano dye the river a blue colour, there is a waterfall, thermal activity and bubbling volcanic gases also in the river. After heavy rain the river loses it´s blue colour due to excessive water.
You can camp at the entrance of the park for US$6 per night. Cabins at the park entrance are available for US$40 per night (April 2008). There is also accommodation further down the road.
