Bioluminescence Paddle on Tomales Bay

Trip Overview

An evening paddle on Tomales Bay is a unique experience, made more spectacular by the abundant bioluminescent plankton that emit small bursts of light with each paddle stroke. It’s an incredible sight to behold! During your trip you will first learn the basics of sea kayaking, safety guidelines for paddling at night, and then have a special opportunity to explore Tomales Bay under the cover of darkness. This trip is great for novice to advanced paddlers of varying abilities.

Bioluminescence is a natural phenomenon and its brightness depends on environmental factors like wind, water temperature, and the amount of ambient light. We choose the darkest nights of summer and fall, which gives us the best chances of seeing a spectacular light show.
