Marine Discovery + Snorkeling Cruise – Port Stephens
The best part of this Port Stephens cruise is the change of pace: you leave Nelson Bay by catamaran, stop to see Bottlenose Dolphins, then trade the boat for a guided snorkel around an offshore island. Back on board, the crew hoist the sails for a quieter ride through the bay.
I like two things in particular: a snorkel guide is in the water with you, ready to point out marine life, and the return under sail gives you time to enjoy the coast without rushing from one stop to the next. The crew’s warm, attentive approach is another plus, especially if you have questions or are travelling with children.
One consideration: wetsuits and towels are not included, and the water portion is only for people who can swim. You do not have to snorkel or swim, but if you plan to get in, bring what you need to stay comfortable.

From Nelson Bay to the open bay

The cruise starts at 8 Teramby Road in Nelson Bay, a practical departure point near public transportation. You meet the crew and board Imagine, a catamaran used for this 3.5-hour outing. The trip is described as a boutique cruise with numbers kept low, though the maximum group size is 40. That cap is worth keeping in mind: this is not a private boat, but the focus is on a guided, small-group experience rather than a large sightseeing vessel.
The scheduled start is 1:30 pm. That timing makes this a handy choice if you want a water activity without giving up the whole day, or if you prefer a later start to an early-morning outing. The duration is approximate, so leave some flexibility around the end of your afternoon rather than planning a tight connection.
The first stretch takes you through the bay. Here, the boat ride is part of the experience, not just transport to the snorkel site. You can settle in, watch the shoreline and get comfortable aboard before the more active portion begins. Coffee or tea is included, a small but welcome touch on a breezy day.

A stop for Port Stephens dolphins
The cruise pauses to visit Bottlenose Dolphins in the bay. That gives you a chance to look for them from the boat before heading farther offshore. The tour is built around wildlife, so it is best to approach this stop with curiosity rather than a checklist: dolphins are wild animals, and the precise encounter can vary.
This pause also breaks up the outing nicely. You are not asked to spend the whole trip in the water, and you get time to enjoy the bay from the deck before the snorkelling stop. If you are travelling with children or with someone who prefers to stay aboard, the dolphin visit gives them something to enjoy even if they choose not to swim.
The crew’s attitude can make a real difference on a boat trip, particularly when you have questions or need help getting ready. The crew are described as welcoming and attentive, and the snorkel guides are there to offer support in the water. That can help you feel more at ease if you have snorkelled before but are unfamiliar with the area.
Snorkelling around an offshore island

After the bay cruise and dolphin stop, Imagine heads to an offshore island for the snorkelling session. The underwater setting is the main reason to book this trip: you may see fish, sea urchins, soft corals and rays among the marine life and vegetation. The exact mix depends on what is present at the site on the day, but the range gives you a sense of what to watch for.
A qualified snorkel guide joins you in the water and points out marine life. That is more useful than simply being handed a mask and fins, especially if you are new to snorkelling or tend to miss small details while scanning the water. Having someone in the water also means you can ask questions as you go, rather than trying to identify everything on your own.
Snorkelling equipment is included, so you do not need to bring your own mask and snorkel. Wetsuits and towels are not included, however. Pack a towel, and consider bringing a wetsuit if you know you get cold in the water. The tour information does not specify water temperature or wetsuit hire, so check with Imagine Cruises if you are unsure what to bring for your date.
You can skip the water activity. Snorkelling and swimming are optional, but you must be able to swim if you want to enter the water. The stated fitness level is moderate, so this is not a purely seated boat tour, even though you can remain aboard instead of snorkelling. If you have limited mobility or are uncertain about getting in and out of the water, ask the operator before booking.
The snorkel stop is described as having a good amount of time in the water, but the total cruise lasts about three and a half hours, with sailing and the dolphin visit included. If you want a full-day snorkelling expedition, this is not that. Its appeal is the combination of a guided swim, wildlife viewing and a scenic cruise in one manageable outing.
Sailing back through the bay

On the return journey, the crew hoist the sails while you relax and take in the coast. This is a lovely contrast to the more active snorkel stop. Instead of returning under power and treating the boat as a ride home, the sail gives the outing a calm, unhurried finish.
That final leg is one of the details that makes the trip feel like more than a snorkelling transfer. You have time to dry off, sit back and watch the shoreline pass. If you have brought snacks or food, outside food is welcome aboard. Snacks can also be bought on board, and alcohol is sold after snorkelling, according to the onboard arrangements. These purchases are extra, not part of the ticket price.
The cruise ends back at the same meeting point in Nelson Bay. There is no separate return transfer to plan, which keeps the logistics simple. The trip is also offered with a mobile ticket, and confirmation is provided at the time of booking.

Is $71.72 good value?

At $71.72 per person, the price covers a 3.5-hour catamaran outing, snorkelling equipment, a qualified snorkel guide, and coffee or tea. You also get a dolphin stop and the return sail. Taken together, that is a solid package if you want a guided water activity rather than simply hiring snorkelling gear and finding your own spot.
The guide is an important part of the value. You are not only paying for time on a boat, but for someone to join you in the water and help you notice marine life. For a first-time snorkeller, that support may be worth more than the equipment itself. For a confident swimmer who prefers to explore alone, the guided element may matter less, though the cruise and sail remain part of the appeal.
There are a few costs to plan around. Wetsuits and towels are not included, and any snacks or alcohol bought on board cost extra. Bring your own food if you want it, since outside food is welcome. That flexibility helps you keep the day within budget.
The cruise has a maximum of 40 people, so do not book expecting a private charter or guaranteed one-to-one attention. The operator keeps numbers to a minimum, but the stated cap means the atmosphere can vary with the group. If having a very small group is essential to you, ask the company about the expected numbers for your departure.
Who will enjoy this cruise most

This outing suits you if you want several Port Stephens experiences in one half-day: a catamaran ride, a dolphin stop, guided snorkelling and a sail back into the bay. It is a particularly good fit if you are travelling with children who are comfortable around boats and water. A family with children aged 10 and 14 had a great time on the trip, so it can work well for school-age children, though each child still needs to be able to swim to snorkel.
It also suits adults who want a relaxed cruise with a little activity built in. You do not have to snorkel, so a mixed group can still share the boat ride and dolphin stop. If your main goal is to stay dry, enjoy the scenery and spend time on the water, you can do that without entering the sea.
Think twice if you cannot swim and hoped to join the snorkel, or if you need a wetsuit and do not want to bring your own. The outing also depends on good weather. If conditions are poor, the operator offers another date or a full refund. If the minimum number of participants is not met, you will be offered a different date or experience, or a full refund.
You can cancel for a full refund up to 24 hours before the start time. Cancellations made less than 24 hours before departure are not refunded, and changes within that window are not accepted. The cut-off follows local time.
Should you book it?

Book this cruise if you want a guided snorkel in Port Stephens with a scenic boat trip around it, rather than a long, specialist snorkelling session. The combination of a dolphin stop, a guide in the water and a sail back makes good use of the 3.5 hours, while the included equipment and hot drink keep the ticket price reasonable.
Before you book, be honest about the swim. You can stay aboard, but the underwater part requires that you can swim, and you will need to bring a towel and any wetsuit you want. If that suits your plans, Imagine is a practical, enjoyable way to get out on the bay and see more than you would from shore.
