Swim with Seals
Wild seals make poor travel companions, but excellent playmates. This 90-minute trip from Plettenberg Bay takes you by speedboat to the Cape fur seal colony at Robberg, where you can snorkel among curious animals in open water. I like the small group limit of 12 people, and I like that equipment and instruction are included, making this far less daunting for first-time snorkelers. The main consideration is that you are entering the sea, so conditions can affect the trip and the activity may feel intense if open water makes you nervous.
The experience combines three pleasures in one: a beach launch, a fast coastal boat ride, and time in the water with a wild seal colony. You are not watching trained animals in a pool or behind a barrier. The seals move freely, come close when curious, and may bump into fins or swimmers.
At $51.47 per person, this is fairly priced for a short wildlife outing that includes transport on the water, snorkeling equipment, instruction, and souvenir photos. I would allow extra time around the scheduled 90 minutes, since the actual outing depends on sea and weather conditions.

Five things to know before you book

- The boat ride is part of the attraction: You launch from the beach and speed along the Western Cape coast toward Robberg.
- The seals are wild and close: They may swim around you, investigate fins, or make brief contact.
- The bay suits beginners: Moderate water temperature and protected conditions can make this a manageable first sea-snorkeling experience.
- Tristen is a guide to look for: One especially praised guide stays close to the group and helps nervous swimmers feel at ease.
- You return to the starting point: The trip begins and ends at Offshore Adventures on Hopwood Street in Plettenberg Bay.
From Hopwood Street to the Robberg seal colony
Your outing begins at Offshore Adventures, at Hopwood Street in Plettenberg Bay. The meeting point is near public transportation, and the activity returns you there at the end, which keeps the logistics simple if you are spending the day in town.
The first part is not a quiet harbor cruise. The boat makes an adrenaline-pumping beach launch into the sea. That sounds exciting, and it is also worth taking seriously. You should be ready to get wet and follow the crew’s instructions as the boat enters the water.
Once aboard, you travel along the coast toward the Cape fur seal colony in the Robberg Marine Protected Area. The ride adds real value to the price because you are not simply being dropped at a snorkeling site. You get a moving view of the coast, a brisk burst of speed, and the feeling of heading somewhere wild.
The boat trip lasts roughly one hour as part of the stated itinerary, while the Robberg portion takes about 30 minutes. In practice, the exact split may change with sea conditions, launch timing, and how the group moves through the activity.

Why Robberg makes the setting special

The swimming area is in the Robberg Marine Protected Area, a protected stretch of the Western Cape coastline known for its fur seal colony. That setting matters. You are seeing animals in the place they use naturally, rather than in a controlled attraction.
The colony can contain a remarkable number of seals. Several accounts describe being surrounded by large groups, with animals moving past in every direction. Their behavior is the star of the trip: they are curious, quick, and playful, with seals flipping, circling, and inspecting swimmers.
Do not expect every seal to approach you. Wild animals decide the distance, and that unpredictability is part of the appeal. You might have one swim close to your fins, while another keeps its distance. A seal may even brush against you or briefly land near a swimmer, but those moments cannot be promised.
There is also a strong smell around a seal colony. That is not a flaw in the operation. It is simply what happens when many seals gather in one place. If you are sensitive to odors, know that this is a wildlife encounter, not a polished aquarium visit.
What the swim feels like in open water

After the boat reaches the colony, you receive snorkeling instruction and enter the water with provided equipment. The water is described as moderate in temperature, and several people found it comfortable even in August. That does not mean you should assume it will feel warm on every departure, but it does make this a more approachable choice for beginners than many cold-water activities.
The bay’s protected nature is another advantage. You are still in the ocean, and you should expect movement in the water, but the location is presented as suitable for people who are new to snorkeling. The crew stays involved, and Tristen received particular praise for remaining with the group and helping a first-time sea swimmer take the plunge.
I like this combination of freedom and support. You are not confined to a cage, yet you are not simply handed a mask and sent off alone. The staff explains what you need to know before you enter and remains attentive while you are near the seals.
Still, this is not a completely relaxed float. The seals are powerful animals, and their playfulness can feel startling when one swims fast toward you. People have described seals tugging at fins, brushing against swimmers, and giving what one person called a few love bites. That sounds funny afterward, but you should treat the animals with respect and follow every instruction from the guides.
The extra arm and leg protectors are a useful detail. Ask the crew about them if you want more coverage in the water. They do not change the fact that this is a wild encounter, but they may help you feel more comfortable around curious animals.
The crew, instruction, and sense of safety

The strongest theme in the feedback is the crew’s professionalism and calm manner. The staff explains the activity before departure, provides the gear, and helps people who feel unsure about open water.
That support can make a major difference. One participant began the trip nervous about being far from shore but finished feeling comfortable. Another person who had never swum in the sea chose to enter the water because the guide stayed close throughout the activity.
Tristen is named as a particularly reassuring guide. If he is leading your departure, you can expect a guide who is present with the group rather than disappearing into the background. Stu was also seen returning a seal pup to the island after it had needed care, adding an unusual glimpse of the operator’s contact with the local wildlife.
The crew also appears to know the area well and can point out marine life beyond the seals. One outing included sightings of humpback dolphins. That kind of bonus is never guaranteed, but it shows why keeping your eyes open during the boat ride matters.
The group maximum of 12 is a real advantage. A smaller group makes it easier to hear instructions, stay near the guide, and avoid feeling lost in a crowd. It also gives the activity a more personal feel than a large boat excursion.

How much time you really need

The advertised duration is about one hour and 30 minutes. The listed itinerary divides this into approximately one hour with Offshore Adventures and 30 minutes at Robberg Nature Reserve.
That is long enough to make the outing feel substantial, but short enough to fit into a busy Plettenberg Bay schedule. You could pair it with another local activity, though I would avoid booking anything immediately afterward. Beach launches, changing, weather delays, and the pace of the group can all affect your timing.
The boat ride is a major part of the experience, not dead time. You travel out along the coast, enjoy the speed, and reach a marine protected area that would be difficult to experience from land in the same way.
If you want a long snorkeling session, this may feel brief. The main point is the close wildlife encounter, supported by a scenic boat transfer. It is best understood as a compact marine adventure rather than a full-day water expedition.
Is $51.47 a good price?

At $51.47 per person, I consider this good value if you want more than a simple wildlife viewing trip. Your price covers the boat outing, snorkeling equipment, instruction, and souvenir photos. Drinks are not included, so bring your own or budget to buy something separately.
The value comes from the variety. In one outing, you get:
- A beach launch
- A fast boat ride along the coast
- Access to the seal colony at Robberg
- Snorkeling with wild animals
- Equipment and safety instruction
- A small group capped at 12 people
A short boat ride alone can cost a fair amount in a scenic coastal area. Adding close contact with a large seal colony makes the price more attractive, especially if this is one of your main wildlife activities in South Africa.
The souvenir photos are a nice extra, although you should not base your decision on them. The best reason to book is the experience itself. You may want to concentrate on the animals rather than trying to manage a camera in the water.
Who will enjoy this most

I would recommend this for people who want active wildlife encounters and do not mind getting wet. It suits couples, small groups, and first-time snorkelers who want clear instruction and a guide nearby.
It also works well for anyone looking for a memorable activity in Plettenberg Bay. Several people considered it a highlight of their South African holiday, and one couple chose it for a honeymoon. The combination of speed, wildlife, and novelty gives it more emotional punch than a standard sightseeing cruise.
You should think twice if you strongly dislike open water, close animal contact, or strong natural smells. The protected bay helps, but this is still a sea activity with wild creatures. Even confident swimmers may find the first approach by a large fur seal startling.
You also need a current valid passport on the day of travel. Most people can participate, but the activity depends on a minimum number of participants and suitable weather.
A few smart ways to prepare

Wear a swimsuit and expect the beach launch to get you wet. Since drinks are not supplied, bring something to drink for afterward.
Listen carefully during the pre-trip instruction. The staff provides the snorkeling equipment, but your comfort will depend on fitting it properly and understanding how to behave near the seals.
If you feel anxious, say so before entering the water. The crew has helped nervous people settle in, and a guide such as Tristen may stay especially close. You do not gain anything by pretending to be comfortable when you are not.
Keep your movements controlled around the animals. The seals are curious, but they are not pets. Give them room, avoid grabbing at them, and let the guide manage the group’s position.
Ask about arm and leg protectors if you want additional coverage. This is especially sensible if you are uneasy about the possibility of a seal brushing against you or investigating your fins.
Weather, cancellations, and booking timing
The experience requires good weather. If poor conditions cancel the trip, you can choose another date or receive a full refund. The same choice applies if the minimum number of participants is not reached.
You can cancel for a full refund up to 24 hours before the start time. Cancellations or changes made within 24 hours are not refunded or accepted, so check the local cut-off time before making changes.
The experience is commonly booked about 28 days ahead. That does not guarantee every departure sells out, but it is a useful sign that reserving early is sensible if your Plettenberg Bay dates are fixed.
Should you book Swim With Seals?
I would book this if you want a close, active encounter with wild marine life and you are comfortable entering the ocean. The speedboat approach, small group, and attentive instruction give the outing more substance than its 90-minute length suggests.
It is especially appealing for beginners, couples, and anyone who wants a standout memory from the Western Cape. Just set the right expectations: the seals are free to behave as they choose, the water can move, and the colony smells like a colony.
Choose it for the wildness, not for perfect control. If that sounds exciting rather than worrying, Swim With Seals is one of the strongest short activities to add to a Plettenberg Bay stay.
