Kayak in Maine's very own Bioluminescent Bay! Experience an unforgettable evening paddle in Castine Harbor under a blanket of stars and in the midst of bioluminescent organisms of the water that swirl and light up with every stroke of your paddle. Fascinating! Castine's Harbor is Maine's own Bioluminescent Bay with a unique ecosystem that creates the perfect environment for these glow in the dark phytoplankton to survive and multiply. In our unique "Floating Planetarium", we'll explore the constellations of the stars of the night sky immersed in the bioluminescent stars of the water! We gather just prior to sunset and after getting outfitted with lifejackets, paddles and lights we head to the docks with our Registered/Licensed Maine Sea Kayak Guide for paddling instruction and then launch our kayaks into the calm mystical night waters of Castine's Bioluminescent Bay...as the light fades the water begins to glow!
