Discover the hidden gem of Costa Rica on this breathtaking full-day tour! Your adventure begins early in the morning as we head towards the Tenorio Volcano National Park, home to one of the country’s most extraordinary natural wonders—the Rio Celeste. Famous for its surreal, sky-blue waters, Rio Celeste is a must-see for nature lovers and adventurers alike. Start with a guided hike through lush, untouched rainforest trails, leading you to the spectacular Rio Celeste Waterfall. Along the way, your guide will reveal the secrets behind the river's unique turquoise colour, a result of a fascinating natural chemical reaction. You’ll be immersed in the sights and sounds of the jungle, with chances to spot exotic wildlife, colourful birds, and tropical plants. As you continue your hike, you’ll reach the “Los Teñideros”—the magical point where two clear rivers merge, creating the remarkable blue colour of Rio Celeste. Marvel at the beauty of this natural phenomenon before exploring the Tenorio Volcano region, learning about its volcanic history, geothermal activity, and the diverse ecosystems that thrive here.
