“We had an absolutely unforgettable experience on the Bio Bay tour in Puerto Rico! From start to finish, everything was smooth, safe, and beautifully organized. Our guide, **David**, was incredible — patient, friendly, and truly passionate about what he does. He made us feel comfortable the entire time and took such good care of us during the kayaking. The moment we reached the bay at night, it felt magical. As we moved our hands through the water, the glowing crystals lit up like stars — something you truly have to see to believe. It was peaceful, breathtaking, and honestly one of the most unique experiences we’ve ever had as a…”

★★★★★★★★★★4.5 · 1,010 reviews · from $172

Spend about 12 hours combining a muddy El Yunque hike with waterfall swims, natural slides, rope swings, and optional cliff jumps, then kayak through mangroves to Laguna Grande after dark. Guides such as Jason, Adriana, Chris, and George lead the rainforest portion, while a separate kayak team handles the bioluminescent bay. Pickup is offered from San Juan.

“Jason and the trip leaders were great! They made the experience fun and had a lot of information about the rainforest. The hike itself was muddy and had quite a bit of rock climbing. While it was beautiful, it was a heavy traffic area. There were long lines for the water activities due to so many groups-and we even went on a Sunday. I don’t regret doing it, it was very fun, but was looking forward to seeing more nature and less tourists. The kayak portion of the trip was fun. It was the off season but we were able to see some of the glow in the water. The…”

7.Overnight Bio Bay Kayak Tour in Vieques Island

★★★★★★★★★★3.5 · 549 reviews · from $65

Paddle Vieques’ famous Bio Bay after sunset with a local guide such as Dillon, Deon, or Adel. The tour includes kayak gear, instruction, van transport, and a short beach stop, but you must stay overnight on Vieques. Expect a simple kayak, a bumpy ride, and the strongest glow on dark, moonless nights.

“The bioluminescent tour with Adel and Travesía group was amazing! Adel (the guide) was very knowledgeable and informative during the whole trip. We were given freedom to roam around while still giving us a great tour and information about the bay. DO NOT USE any repellent, as there are no mosquitoes in the bay. If you can, try to plan it during a sunny day and a new moon. The bay will be darkest and it will make for a great experience. I took a 7-year with exceptional needs with us and she had a blast.”
