We leave La Fortuna at 7 a.m. for this fascinating adventure combining a discovery of nature's magic with the chance to observe wonderful flora and fauna. The tour lasts approximately 10 hours all together and on clear days it's possible to get a view of the Arenal, Tenorio and Miravalles Volcanoes and sometimes even Lake Nicaragua.

The Celeste River zone is one of the most beautiful areas of Costa Rica. On the way we stop for a rest in a picturesque village and then continue on towards the "Rio Celeste" in the Tenorio Volcano National Park. On arriving at the Park we set off on a 7km (approximately 4 miles) hike which passes by the River Celeste Lagoon, a great place for taking photographs. Finally we arrive at the river itself where mother nature magically mixes the water of two crystal-clear streams, changing the water's color to a beautiful bright, light-blue (hence the name "Rio Celeste" or Light-Blue River).

The hike continues on through the mountains on rough paths into the jungle discovering an area of the volcano where gases are expelled at very high temperatures. At the end of a steep but interesting walk down, we get to see, in all its splendor, the Rio Celeste Waterfall which is impressive not for its size but for its unique colors.

After the waterfall there is a tough hike back to the park entrance where we are served a delicious, well - deserved lunch.
