Exploring Cornwall’s Kelp Forest in Summer

#explorenature #gardendesign #people
The Cornish coastline is a place shaped by constant, dramatic change.
At the peak of summer, the cold, stark winter reefs of Falmouth have undergone an incredible transformation. Below the surface, sunbeams pierce through the water column to illuminate a towering, majestic kelp forest. This is Cornwall's underwater jungle—a thriving, vibrant sanctuary teeming with life, from microscopic wonders to the ocean's silent giants.
In this film, we explore the green-blue canopy of this spectacular marine world, experiencing the best of Cornwall’s summer diving.
Swimming through the towering kelp fronds, we find ourselves surrounded by massive, swirling shoals of juvenile pollack. Down on the rocky seabed, tucked safely into the kelp holdfasts, we encounter Cornwall’s mini catsharks resting quietly during the day and hunting for food. A highlight is discovering the kelp’s true gentle giants — peaceful nursehound sharks, curled up and snoozing in the rocky shadows.
We also slow down to appreciate the smaller, brilliant details of the reef. We watch elegant dahlia and snakelocks anemones swaying in the swell, look out for the vibrant, blue-‘winged’ gurnards on the sand, and spot delicate summer jellyfish drifting gracefully in the open water
