Bayplay (Snorkel with Sea Dragons)

Guided snorkel trips off Portsea on the Mornington Peninsula head out over the seagrass and reef of Port Phillip Bay in search of weedy seadragons, with an in-water guide and a skills briefing for newcomers. The award-winning operator also runs beginner scuba experiences and PADI courses, sea-kayak and paddleboard tours, guided walks and marine-education programs for schools, plus its own group accommodation in Portsea. Trips run year-round, including through the colder months when the bay's marine life is at its most active.
