The Experience

First thing I noticed was the mist clinging to the hills as we left San José — not quite rain, just that damp air that makes your hair curl. Our guide, Andrés, kept us awake with stories about the volcanoes and why Río Celeste is so blue (something about minerals mixing — I’ll admit I zoned out staring at cows grazing by the road). By the time we reached Tenorio National Park, my shoes were itching for a walk. The forest here feels alive in a way that’s hard to explain — everything buzzes or drips or calls out. We stopped suddenly when someone spotted a sloth curled up like a mossy pillow. Andrés grinned and whispered “perezoso,” which I tried to repeat but probably mangled.

The waterfall itself… well, it’s not like any blue I’ve seen before. It almost glows against all that green. The spray hit my face and tasted faintly metallic — maybe from the volcanic stuff? There were locals on the trail too, families with kids pointing at toucans overhead. At one point we passed these bubbling pools where you could actually smell sulfur in the air (not my favorite scent but kind of cool). Lunch after all that walking was at this small spot run by a family — rice, beans, fried plantains, chicken stewed in something sweet-smelling. I ate too fast and regretted it later but honestly it was worth it.

I didn’t expect to be able to swim in Río Celeste itself — turns out our group had access to this private bit outside the park. The water felt cold at first but then weirdly soft on my skin; someone said it’s good for asthma? Not sure if that’s true but floating there looking up at tangled branches above… I still think about that moment when everything went quiet except for birds somewhere off in the trees.

The drive back felt long but not boring. We stopped at Caldera beach just as the sky started turning gold and pink. There was salty wind and some local guy selling ice cream from a cart — coconut flavor for me (sticky fingers after). Watching waves roll in while licking melting ice cream is maybe not glamorous but it felt perfect right then. So yeah, if you’re thinking about a day trip to Río Celeste from San José, this one covers more than you’d expect.
