Come discover the mysterious creatures that live below the pier at Boston Harbor Marina! Our trained biologists provide underwater lights that attract spectacular estuary creatures for you to safely scoop up and observe, while our volunteer naturalists help you identify and learn more about what you’ve found. From octopus to anemones, from sea stars to sea slugs, you never know what you’ll encounter! Pier Peer is one of our most popular events, so register early to ensure your spot.
