Puerto Rico: El Yunque Hike & Bio Bay Kayak Combo Tour

Summary

El Yunque rainforest hike to waterfalls then night kayaking in glowing waters

You’ll hike through El Yunque’s wild rainforest with a local guide, swim under waterfalls, share lunch at a small Puerto Rican spot, then paddle through pitch-black mangroves into Laguna Grande’s glowing bio bay. Expect mud on your shoes, laughter with strangers, and moments that stick with you long after you’re home.

What’s the experience like?

I didn’t expect my shoes to get swallowed by mud before breakfast, but that’s how our day started near El Yunque. The air felt thick with green—like you could almost taste the leaves. Our guide, Javier, kept grinning at us as we stumbled over roots and tried not to slip. “Careful here,” he’d say, but honestly I was too busy gawking at the bamboo and these tiny orange flowers everywhere. Someone behind me muttered about their socks being ruined forever. We all laughed—no one cared.

The first pool was colder than I thought it’d be, but after sweating through the hike it felt good. There was this moment where I just floated on my back, looking up at tangled branches and sky, and everything went quiet except for the water sliding over rocks. Javier showed us how to swing from a rope into the deeper part (I chickened out the first time). Lunch happened somewhere between wet hair and muddy legs—fried plantains and chicken at a roadside place where nobody rushed us. I still think about that view from our table, all misty hills in the distance.

By nightfall we were east at Laguna Grande for the bioluminescent bay kayak tour. It’s darker than you’d expect out there—the kind of dark where your paddle disappears until you dip it in and suddenly blue sparks swirl around your hands. Our eco-guide explained about the plankton (pyrodinium bahamense—I probably spelled that wrong), but honestly I was too busy swirling water like a kid. Sometimes it glowed bright, sometimes less so—Javier said it depends on moon phases and rain, so don’t expect a movie scene every time. We finished with sticky hands from some snack bars they handed out before driving back to San Juan half-asleep.
