If you ever have the chance to hike Río Celeste, it will be an unforgettable experience—and the best way to enjoy it is on a guided tour through Tenorio Volcano National Park, home to one of Costa Rica’s seven natural wonders. This tour includes hotel pickup (private in some areas) and is led by a bilingual naturalist guide who begins sharing insights from the start. On the way, you may spot wildlife like sloths, monkeys, and toucans, as well as enjoy views of the Tenorio and Miravalles volcanoes and rural Costa Rican life. The hike starts in a secondary forest, great for birdwatching, and continues into a primary forest, where signs of tapirs and other wildlife may be found. Highlights include the breathtaking Río Celeste Waterfall, the Blue Lagoon, the volcanic “borbollones,” and the magical Teñideros, where two clear rivers meet and instantly turn turquoise blue—a phenomenon unique to this region. This natural marvel, combined with expert guidance and lush rainforest surroundings, makes for a truly enriching adventure you won’t want to miss.
