Bioluminescent Evening Kayak Tours

Tours available annually outside of our expedition schedules, on weeks on/near the new moon, for best visibility.

Our Bioluminescence kayak tours are designed for families and groups of adults and families to explore one of the Pacific Ocean’s most beautiful phenomena: Bioluminescence.

Bioluminescence is the production and emission of light by a living organism. On dark (moonless) nights on Tomales Bay, bluish white flickers are visible in the water column, which come from blooms of bioluminescent “dinoflagellates”. These tiny critters emit short flashes of light and at certain times of the year put on quite a show for kayakers. Schools of fish in the bay create a luminescent trail which can look like a glowing cloud in the water. All this glowing activity is only visible at night when the sun and moon are both down and there is no ambient light interference. Accordingly, we have set up evening paddles which should afford good viewing after we enjoy the beautiful sunset.

2026 Dates TBD for youth and families. Please email info@girlventures.org for more details.

All fees generated from these trips go to support youth outdoors.
