Gansbaai Whale Watching – Walker Bay
Departs Gansbaai Harbour
An approximately two-hour boat cruise leaving directly from Gansbaai Harbour into Walker Bay and along the dramatic De Kelders sea cliffs — Southern Right Whales, humpbacks, Bryde's whales, dolphins, seals and marine birdlife with an expert marine guide.

The quieter, more scenic Walker Bay boat trip
Gansbaai Whale Watching – Walker Bay departs from Gansbaai Harbour and explores the Gansbaai and Walker Bay coastline. This is a separate whale-watching experience from our Dyer Island trip departing nearby Kleinbaai Harbour.
Instead of launching from the busy Hermanus New Harbour on the far side of the bay, 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.
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. If you have already done a Hermanus trip, Gansbaai gives you the opposite coastline of the same bay.
This boat trip runs under a South African government whale watching permit with a qualified marine guide on board. South African Adventures helps guests discover, plan and book trusted adventure experiences in South Africa.

Which Gansbaai Whale Watching Trip Should I Choose?
South African Adventures offers two genuinely different Gansbaai whale-watching boat trips. Both are Gansbaai-area experiences — the difference is the harbour you launch from and the stretch of ocean the boat works. Walker Bay stays inside the bay along the De Kelders cliffs from Gansbaai Harbour; the Dyer Island trip heads offshore from Kleinbaai Harbour, a few minutes further along the same coast. Neither is better — they simply show you different water.

What to Expect at Gansbaai Harbour
Check-in is 30 minutes before departure at the Gansbaai Harbour office. Gansbaai Harbour is the historic Old Harbour of the fishing town of Gansbaai — 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.
A mandatory safety briefing is given before boarding and life jackets are issued. Boarding involves a short step from the quay onto the vessel.
You then spend approximately 2 hours on the water, cruising east from the harbour into Walker Bay and along the De Kelders coast. Total time at the harbour is around 2.5 hours.
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. The marine guide interprets behaviour, identifies individuals from callosity patterns and shares the conservation story of the Southern Right recovery.
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. Sea caves and the Klipgat archaeological cave are visible from the water.
Best Time for Walker Bay Whale Watching
The Southern Right Whale season runs from June to early December, with September and October the absolute peak — cows and calves come into Walker Bay to rest under the De Kelders cliffs.
Humpback whales pass through in early winter (May to July) and again in late spring (October to December) on migration. Bryde's whales, dolphins and Cape fur seals are seen year-round, and ocean sunfish drift into the bay from December to March.
Wildlife You May See in Walker Bay
Southern Right Whales
June to early December, peak September and October. Cows and calves make up most sightings on the Gansbaai side of the bay, often within 100 metres of the cliffs — lobtailing, sailing, spy-hopping and occasional full breaches.
Humpback Whales
May to July and October to December, passing through on migration between Antarctic feeding grounds and tropical breeding grounds. Great acrobats — breaching, tail-slapping and pec-slapping.
Bryde's Whales
Resident year-round in Walker Bay, hunting sardine, anchovy and squid. Fast and sleek, often seen lunge-feeding among gannets and dolphins on baitballs.
Dolphins
Common dolphins in super-pods of several hundred, and bottlenose dolphins in smaller inshore groups. Both regularly bow-ride the boat.
Cape Fur Seals
Small groups rest on rocks near the harbour and in the water along the coast. The huge Geyser Rock colony lies further east and belongs to the Dyer Island trip, not this one.
African Penguins
Endangered African penguins sometimes forage in Walker Bay. The nearest breeding colony is on Dyer Island, offshore of Kleinbaai, so sightings here are opportunistic.
Ocean Sunfish (Mola mola)
December to March, drifting into the bay to be cleaned of parasites. The distinctive dorsal fin lolling on the surface is often mistaken for a shark.
Marine Birdlife
Cape gannets diving on baitballs, Cape and crowned cormorants, African black oystercatchers, kelp gulls, Antarctic terns and — in winter — the occasional shy albatross or giant petrel.
Wildlife sightings are never guaranteed. The skipper chooses the route according to conditions, safety and recent sightings.
Weather Policy
All departures are subject to sea and weather conditions. The skipper's decision is final and is always erred on the side of safety.
If a trip is cancelled by the operator, you are re-booked onto the next suitable departure or fully refunded. If you cancel because of a weather forecast, standard cancellation terms apply — always make contact first so you can be advised.
Accessibility: boarding involves a short step from the quay onto the vessel. Guests with mobility challenges are welcome — mention it when booking so assistance can be pre-arranged and you can be seated close to the boarding point. Very young infants under 12 months are generally not recommended for open-water trips.
