Puerto Vallarta: Bioluminescence in Los Arcos Marine Park

Imagine watching the water glow with a surreal blue shimmer, illuminated by tiny organisms responding to your movements. That’s exactly what you get on the Bioluminescence Tour in Los Arcos Marine Park — a magical escape just south of Puerto Vallarta. For $76 per person, this 2.5-hour evening adventure offers a chance to witness an otherworldly spectacle, learn about local wildlife, and enjoy a stunning sunset in one of the area’s most picturesque beaches.

Two things we love about this tour: first, the expert guidance from knowledgeable local guides who share insights into the fauna and flora, enriching every moment; second, the opportunity to swim in bioluminescent waters, which is truly an experience unlike any other. The tour’s small-group format ensures a more intimate experience, letting you soak in the natural beauty without feeling rushed.

That said, a couple of considerations are worth noting. Since the tour involves a boat ride in open water, it’s not ideal for those prone to seasickness or with mobility issues.

The transfer time isn’t specified, but expect it to be a quick and comfortable ride—probably around 30 minutes.

The Sunset and Marine Park Tour
Once you arrive, your guide takes a moment to prepare the group for what’s ahead.

The guides are attentive, offering explanations in both Spanish and English, which keeps everyone engaged and informed.

You’ll love the way the landscape is lit up in this golden hour, making for excellent photo opportunities. The guides often share interesting facts about the area’s natural history, adding depth to the visual feast.

Many reviews highlight this as a “spectacular,” “unimaginable,” and truly “a once-in-a-lifetime experience.” Guides explain the science behind bioluminescence, making the spectacle both fascinating and educational.
