###Group Sizes
We set two departure times to stagger the groups. Both departures go to the same location and operate the same tour. Each departure has a maximum of 10 guests with two guides. This ensures not only your safety but also complete access to your guides so you can ask any questions and hear all the great information they share. Our goal is to provide an experience, not a cattle drive.
###The Bioluminescence Kayak Experience
🌌 Discover the Magic. Paddle into Wonder.
Be part of the original—and most acclaimed—Bioluminescence Kayak Tour on San Juan Island. Years ago, we pioneered this mesmerizing nighttime adventure before anyone else, and today it stands as our most sought-after experience.
🛶 What Awaits You: Set off just before sunset into a serene, protected bay, chosen for its ideal conditions and actively monitored bioluminescent activity. As twilight deepens, you'll glide at a peaceful pace, anticipating the moment when the waters below erupt with ethereal light.
✨ Guided by Expertise: Our seasoned kayak guides will lead you to the most vibrant bioluminescent zones while unraveling the scientific mysteries and ancient lore surrounding this natural phenomenon. Every guide undergoes rigorous training and mentorship in kayaking, San Juan wildlife, and regional history, bringing unmatched insight and safety to your journey.
🌑 Optimized for Awe: We carefully select specific dates each month to ensure the darkest nights, allowing the bioluminescence to truly shine. Bright moonlit evenings? We avoid them to protect the magic.
👥 Intimate Group Sizes: Enjoy a personalized experience with the island’s smallest tour group sizes. This ensures clear communication, one-on-one connection with your guide, and a more immersive adventure. Want to bring a larger group? We offer custom private tours—just ask.

##Duration and Departure
The tour takes an estimated 3.5 hours door to door. Approximately 2 to 2.5 hours of water time. Time on the water can vary night to night. Departure times vary with the sunset time. See the calendar for exact times and dates.
Check-in Time for Bioluminescence Kayak Tours is 15 minutes before the reserved departure time.
Location: 260 Spring St. Friday Harbor, WA. We have a brick-and-mortar location. So you will meet us at our office, not the side of the road randomly in town.
##Why We Have Limited Dates
If we could, we would offer this kayak tour every night. But with our years of experience, we have honed in that only certain dates on the calendar will ensure the best experience.
We choose to paddle around the darkest nights of the month based on the moon phase. Once the moon gets to approx, half (50%) it will be too bright on the water to see the Bioluminescence through the reflection of the moon.
You may see companies offering Bioluminescence Kayak Tours when the moon is 50% or greater. Paddling under a big, bright moon is great, it is just not a Bioluminescence Kayak Tour.
