In Monteverde, we struck up a conversation with a fellow hiker who suggested we visit Rio Celeste, a turquoise river and lagoon in Tenorio Volcano National Park. The color is an effect of a chemical reaction between sulfur and calcium sulfate. Pretty hike, but rubber boots are advisable. Lucky for us, there doesn’t seem to be public transport along the dirt road into the park. We set camp in the parking lot, and soon were asked if we were going back into town. Another visitor needed a ride out of the park 7km to the nearest village. That must have been a long walk as dusk was approaching.
Our pictures seem to have disappeared for this park. Internet to the rescue.
