Prepare to be mesmerized by the surreal, turquoise waters of Río Celeste, a true gem tucked within the Tenorio Volcano National Park. Your journey follows a roughly 3.7-mile trail through a lush rainforest, leading you to the breathtaking main waterfall, which requires a descent of about 250 steps. The hike itself is a moderately challenging adventure, with the path from the car park to the waterfall entrance taking about 30 minutes, but the reward is a sight you'll never forget—a river that local legend says got its color when God dipped his paintbrush in it after painting the sky.
