If you’re looking for a memorable aquatic adventure along Australia’s stunning Mornington Peninsula, this 3-hour Dolphin and Seal Swim tour offers a blend of wildlife encounters, scenic cruising, and snorkeling. It’s a package that promises both thrill and tranquility—perfect for lovers of marine life and those seeking a hands-on experience with nature’s most playful creatures.
What makes this tour stand out? First, the chance to swim with Australian Fur Seals at Chinaman’s Hat—an unusual and captivating experience.

The boat itself is comfortable, with multiple levels for lounging and excellent amenities such as a café and clean bathrooms—important comforts when you’re spending several hours on the water.
Looking for more options in Mornington Peninsula? Here are some other experiences worth considering.
Our first stop takes us to the manmade Chinaman’s Hat, a small island known for its large Australian Fur Seal population. Here, the seals are inquisitive and unafraid of humans, allowing snorkelers to come face-to-face with these playful, curious animals. Reviewers consistently praise the seals’ friendliness: “The seals were incredible,” reports Donna_N, emphasizing how engaging this part of the trip is.
The seals vary in age and size, and many travelers find their playful antics charming. We loved the way guides manage interactions to ensure the seals are not disturbed, maintaining a respectful distance and avoiding disruption to their natural behaviors. The shallow waters make snorkeling accessible for most, and you can expect to spend plenty of time observing these creatures in their habitat.
Back on the boat, a well-deserved lunch break provides nourishment before heading out to search for dolphins. The meal is simple but sufficient, allowing everyone to recharge. As one reviewer noted, “Nice cake and drinks for breaks” — a thoughtful touch that helps maintain the energy for the next leg of the journey.
Once the crew locates a pod of dolphins, the atmosphere shifts to anticipation. Guides observe their behavior carefully, giving the group hints on when to approach. When the moment feels right, small groups of ten slide into the water to see these majestic animals up close.
Expect to float and wait, listening for their squeaks and whistles—signs they’re about to swim near. The encounters are entirely unique: sometimes the dolphins swim around you endlessly, other times they just pass by. The reviews reflect this unpredictability: “Sometimes they will swim around us for endlessly,” shares Donna_N, while Antonina_P describes it as “a lot of dolphins and seals playing around in the water.”
While the experience is mostly about observation, the guides’ emphasis on respecting marine life ensures these animals are not disturbed. This approach makes the tour both ethical and rewarding.
The tour is designed to maximize wildlife viewing and interaction without compromising animal welfare. It lasts approximately three hours, including the cruise, snorkeling with seals, lunch, and dolphin viewing. The small group size (max 30 travelers) means you’re not just another face in the crowd—guides can focus on individual needs and ensure everyone gets a chance to participate.
At just over $150 per person, the tour offers excellent value, especially considering the personalized experience and multiple wildlife encounters. The ability to return for free within three months if you don’t see dolphins on your first try adds peace of mind—an attractive bonus for those anxious about wildlife sightings.
Many travelers find the guides to be friendly and knowledgeable, enhancing the overall experience. “The staff were so amazing and friendly!” says Rachel_L, emphasizing how the guides make the tour approachable and fun. Others highlight the stunning views and the thrill of being so close to wildlife: “So many dolphins and seals played around in the water,” reports Antonina_P.
The main consideration is the unpredictability of wildlife sightings, especially dolphins. While the tour makes every effort to locate them, nature can’t be guaranteed. Also, booking through third-party providers like Viator has occasionally caused scheduling confusion, as some reviewers noted. It’s advisable to confirm your time and details directly with the tour provider if possible.

This experience is perfect for adventurous travelers, families with older children, and wildlife enthusiasts. If you enjoy snorkeling or are open to trying it, you’ll likely find this a rewarding outing. It’s also ideal for those seeking an eco-conscious adventure that emphasizes respect for marine life.
People with a sense of curiosity about Australian Fur Seals and dolphins will appreciate the chance to observe and interact with them in their natural environment. Since the tour is about authentic encounters rather than commercialized performances, it suits travelers who value genuine experiences over superficial attractions.

This 3-hour Dolphin and Seal Swim tour offers a compelling mix of wildlife encounters, scenic cruising, and the chance to get close to the sea’s most charismatic creatures. The inclusion of seals at Chinaman’s Hat is a highlight, providing intimate moments with inquisitive animals that will stick in your memory.
The flexibility of departure times, the well-equipped boat, and the friendly guides all add to the value. Plus, the option to revisit if you don’t see dolphins on your first try makes it less stressful for first-timers. It’s a well-rounded experience for those who love the water and wildlife, seeking authentic, respectful encounters.
While wildlife sightings can never be guaranteed, the overall setup prioritizes safety, comfort, and conservation, making it a responsible choice for eco-minded travelers. If you’re eager for a hands-on adventure with seals and dolphins and don’t mind some unpredictability, this tour could be a highlight of your Mornington Peninsula visit.
