Why choose Gansbaai Whale Watching
Gansbaai Whale Watching is the quieter, more scenic Walker Bay boat trip. Instead of launching from the busy Hermanus New Harbour, you leave from the working fishing harbour of Gansbaai and cruise east along the towering De Kelders sea cliffs — one of the most photogenic stretches of coastline in South Africa. Because the vessels are small, launch numbers are limited, and Southern Right Whale cows and calves shelter directly under the De Kelders shoreline every winter, encounters are calm, close and unhurried.
- Prime whale nursery water. The stretch of Walker Bay between Gansbaai Harbour and De Kelders is arguably the single densest calving zone for Southern Right Whales anywhere in Africa.
- Small-boat departures. Uncrowded decks, unobstructed views, personal attention from the marine guide.
- Dramatic scenery. Sheer sandstone cliffs, sea caves, and the Klipgat archaeological cave visible from the water.
- Expert marine guides. Every trip runs with a qualified guide narrating whale behaviour, marine ecology and Overberg conservation history.
- Different vantage point. If you have already done a Hermanus trip, Gansbaai gives you the opposite coastline of the same bay.
About Gansbaai Harbour
Gansbaai Harbour is the historic Old Harbour of the fishing town of Gansbaai, roughly 45 minutes' drive from Hermanus and about two hours from Cape Town. It is a small, protected launch site sheltered by a stone breakwater. Parking is free and unrestricted, the harbour office is a few steps from the boat, and check-in is unhurried — nothing like the crowds you occasionally see at bigger tourist harbours. From the harbour it is a short cruise east into Walker Bay and along the De Kelders coast.
Walker Bay and the De Kelders coastline
Walker Bay is the sheltered, crescent-shaped bay between Hermanus and Danger Point. The Gansbaai side of the bay is defined by the De Kelders sea cliffs — a wall of pale sandstone that plunges directly into deep, protected water. This underwater shelf is why Southern Right Whales choose the area to give birth and nurse. The same geometry that shelters the calves also makes for exceptionally calm boat cruising, and the cliff face reflects and amplifies the whale calls you sometimes hear on the surface.
For a broader look at the bay itself, see the Walker Bay Whale Watching Guide, Southern Right Whales in Walker Bay, and Walker Bay Marine Life.
Whale species throughout the year
Southern Right Whales (June – early December)
The headline species. Female Southern Rights migrate from Antarctic feeding grounds to Walker Bay to calve and nurse. Cows and calves make up the majority of sightings on the Gansbaai side of the bay, often within 100 metres of the cliffs. Peak: September and October. Behaviours you can expect to see include lobtailing, sailing (holding a tail fluke to the wind), spy-hopping and — on lucky days — full breaches.
Humpback Whales (May – July and October – December)
Humpbacks pass through on their long migration between Antarctic feeding grounds and tropical breeding grounds off Mozambique. Encounters are shorter than with resident Southern Rights, but Humpbacks are the great acrobats of the whale world — breaching, tail-slapping and pec-slapping regularly.
Bryde's Whales (year-round)
Bryde's Whales (pronounced "broo-duhs") are resident year-round in Walker Bay, hunting sardine, anchovy and squid. They are fast, sleek and often seen lunge-feeding among gannets and dolphins on baitballs.
Dolphins
Two species are common: common dolphins in super-pods of several hundred, and bottlenose dolphins in smaller inshore groups. Both regularly bow-ride the boat.
Cape Fur Seals
You will pass small groups of Cape fur seals resting on rocks near the harbour and in the water along the coast. The main colony of tens of thousands lives further east on Geyser Rock — that is the domain of the Kleinbaai Marine Safari, not this trip.
African Penguins
African penguins (endangered) sometimes forage in Walker Bay. The nearest breeding colony is on Dyer Island, offshore of Kleinbaai. Sightings from Gansbaai Harbour trips are opportunistic.
Sunfish (Mola mola)
In the warmer summer months (December – March) ocean sunfish drift into the bay to be cleaned of parasites. Distinctive dorsal fin lolling on the surface — often mistaken for a shark.
Marine birdlife
Cape gannets diving on baitballs, Cape and crowned cormorants, African black oystercatchers on the rocks, kelp gulls, Antarctic terns, and — during winter — the occasional shy albatross or giant petrel following fishing vessels.
Professional marine guides & responsible whale watching
Every trip runs under a South African government whale watching permit, in strict compliance with the 300-metre minimum approach distance and engine-off protocols for close encounters. Whales approach the vessel on their own terms, not the other way around. Our marine guides interpret behaviour, identify individuals from callosity patterns, and share the science and conservation story of the Southern Right recovery.

Weather policy
All departures are subject to sea and weather conditions. The skipper's decision is final and always erred on the side of safety. If a trip is cancelled by us, you are re-booked to the next suitable departure or fully refunded. If you cancel because of weather forecasts, standard cancellation terms apply — always contact us first so we can advise.
Accessibility
Boarding involves a short step from the quay onto the vessel. Guests with mobility challenges are welcome — please let us know at booking so we can pre-arrange assistance and seat you close to the boarding point. Very young infants (under 12 months) are generally not recommended for open-water trips.
Photography tips
- Wrist-strap or neck-strap on every camera — salt spray and sudden waves are unforgiving.
- Set continuous burst mode; breaches are over in less than a second.
- Wide zoom range (24–200 mm) is more useful than a long telephoto — the whales are often close.
- Polarising filter cuts sea glare beautifully.
- Phone shooters: lock exposure on the water surface, not the sky, or your whale will silhouette.
What to bring
- Windproof jacket and warm layer — the sea breeze is cool even in summer.
- Beanie, closed-toe shoes, sunglasses, sunscreen.
- Water bottle and a light snack.
- Camera or phone with wrist strap.
- Seasickness tablets 30–45 minutes before departure if you are prone.
