Discover one of the most amazing sights in Costa Rica on a full-day tour of the Tenorio Volcano National Park, part of the Arenal Tilaran Conservation Area, including a 3.5-hour hike to the crystalline waters of Los Teñideros in the Celeste River. Marvel at the magnificent turquoise waters and surrounding nature of the Rio Celeste. Located on the flanks of the Tenorio Volcano, the river is unique in Costa Rica and astounds visitors with its natural beauty. A circuit trail of 4.2 miles (7 kilometers) will take you through the forest, passing scenic spots such as Los Teñideros, where the river acquires a different color due to the chemical reactions. Visit the mud-filled fumaroles of Las Ollas (“Cooking Pots”), legendary for their healing properties. Continue to a startling turquoise waterfall of the Rio Celeste, before heading back along the banks of the river, enjoying the bubbling water and the nature surrounding you along the way. Finish your tour of one of the most interesting places in Costa Rica with a delicious lunch.
