Bioluminescent kayaking is the first time I've ever LOVED fog before. On the first half of our journey, we kayaked across Tomales Bay through thicker fog, which was actually really cool, because you kind of felt like you were in a bubble the whole time because the atmosphere is opaque. We couldn't see the wildlife as well as on a clear night, but we could hear it and see it some. It was eery and beautiful and you could just see the shapes of the islands as we neared, until they came into full view. The whole paddle there felt like a cross between a mystical adventure conjuring up images of Scotland, and a scary movie which was funny and fun and we had a great group laughing and making jokes. When we landed on the beach at Hog Island, it was just starting to get dark. The guides set up tables and we had hot cocoa and brownies, cookies, fruit cobbler bars, chocolate croissants and almond croissants TO DIE FOR from a local bakery in Point Reyes. After our dessert picnic on the beach, it was dark and someone shouted that the bioluminescence had begun. I still had NO IDEA what that meant. I ran over to the water... which looked normal to me... until my friend ran into it and started moving around. HOLY COW. It's like GLOW IN THE DARK WATER. When you move, the water glows for a few seconds where the movement occurred. If you swirl it in circles, there's a glowing circle in the otherwise "black" water. If you send a spray of water in the air, it glitters across the sky and sparkles when it lands back on the water again. If you run your hand through the water, it glows all around it, and when you lift your hand back out, it glitters like a brilliant night sky during a meteor shower. I felt giddy and ridiculous the whole time just staring at my hand being like OMG IT'S GLITTERING! Fish swim by in beautiful glowing streams that look like comets and moon beams. It's INCREDIBLE. INSANE. MAGICAL. Le sigh. The fog was so thick (the thicker the better for this kind of thing), the bioluminescence lasted ALL the way back to shore. It usually stops about halfway back because of light pollution. I don't recommend this trip, I think it's mandatory for anyone who wants adventure, beauty and magic for an evening.
