Join us on one of our boat trips to explore the UK’s first National Marine Park.

Embark on an unforgettable adventure with the Ocean Conservation Trust as we explore the UK’s first National Marine Park. Our boat trips offer a unique and enriching experience unlike any other, where you’ll gain a deeper understanding of marine life and conservation efforts.

Join our Ocean Discovery Rangers and Marine Biologists on a journey that goes beyond the typical boat trip. Learn about the importance of seagrass meadows, encounter fascinating local marine species such as Spider crabs and Starfish, and participate in a plankton trawl to observe these microscopic marvels under a microscope. Additionally, delve into the rich history and natural beauty of Plymouth’s stunning harbour.
