Maine's very own Bioluminescent Bay!
*Featured in DownEast Magazine Sept. 2004 !
*Yankee Magazine Editors Choice~Best Night Paddle 2013

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!
We provide: Kayak, Paddle, Lifejacket and Expert Maine Sea Kayak Guides as your leaders!!

This tour is best suited for folks with previous paddling experience, which we require along with a reasonable level of fitness to control and steer your craft and comfort with the water at night. If you have never paddled or would benefit from more experience, we highly recommend joining us for a day trip to gain more comfort and enjoy our beautiful area before undertaking paddling at night. We are offering a Special Sea Kayak Castine by Day and Night Combo Package: Paddle by day first and learn to maneuver your kayak efficiently with our guide's instruction making your night trip more relaxing and enjoyable! Book now and receive 20% off your day tour when booked together within the same day, week, month or summer!
