Polperro Dolphin Swims

Polperro Dolphin Swims has run marine wildlife tours from Sorrento Pier for over 20 years, operating small-group in-water dolphin encounters and seal swims in Port Phillip Bay. The operator holds marine mammal interaction licences from DELWP and uses a rigid inflatable boat (RIB) to reach dolphin populations in the Bay. Groups are capped at 12 participants, keeping encounters genuinely intimate.

What they are good at

In-water dolphin encounters delivered reliably in small groups with experienced marine guides. The pier-based departure removes much of the logistics anxiety, and the format is well-suited to families with children aged 8 to 14 who want a genuine wildlife experience rather than a passive boat cruise.

Not suited for

Families with children under 8 who want to swim, and guests seeking a spectator-only wildlife experience. Anyone with a strong aversion to cold water should note that Port Phillip Bay temperatures range from around 13 degrees Celsius in winter to 22 degrees in summer.

Pricing, seasonal departures, and group bookings are managed on the operator's own website.
