# Puerto Rico Bio Bay Kayak Adventure Tour

**Guidekin's take:** A night kayak through the sheltered mangrove canal into Laguna Grande, where the water glows around each paddle stroke, with snacks, gear and a full safety briefing in the price. From age six, guests are weighed at check in against the kayak limit, and no transport from San Juan. 4.59 from 1822 reviews at €61 per person.

In our comparison: #69 of 70 in Day Trips, by rating weighted by review volume (table below).

## Overview

Want a glowing and unforgettable night? This Bio-Bay Kayak Tour is what you need!

On this tour, you will cross a canal inside the nature reserve that is surrounded by various types of mangroves. This protects from strong winds and helps you to paddle easily in peaceful waters.

The best part of this tour is to enjoy the incredible glittering water of the "Big Lagoon"! Tiny bioluminescent organisms called "pyrodiniums bahamenses" are the responsible for this wonder of nature. They produce blue-green light from top to bottom of this bay every time you touch or move the water with your kayak!
