Southern right whales were hunted down to roughly sixty breeding females in South African waters before international protection arrived in 1935. The population has climbed steadily since, and Walker Bay is now one of its most reliable nursery grounds.
That recovery is the reason whale watching boat Cape Town tours exist at all. Departures leave from New Harbour on Westcliff Road, a working slipway built for trawlers in the 1950s, not a purpose-built cruise terminal. The diesel smell is part of the record.
The town itself began as a watering place. Around 1815 a travelling teacher named Hermanus Pieters drove his flocks to a freshwater spring above the cliffs; the settlement that grew there was called Hermanuspietersfontein until postal clerks shortened it in 1902. Fishermen worked the Old Harbour below the cliffs from the 1850s, hauling snoek and kabeljou up a stone ramp that is now a national monument. Hermanus later appointed a whale crier, who blows a kelp horn in coded sequences to signal where the animals have surfaced — a job that exists nowhere else.
Its reputation rests on bathymetry. Walker Bay shelves gently and drops to sheltered depth close inshore, so cows with calves lie within a few hundred metres of the rock. South African regulations hold general vessels 300 metres off; only permit-holding boats may close the gap, and those permits are deliberately scarce. A Hermanus whale watching cruise therefore operates under conditions closer to fieldwork than sightseeing, with skippers logging callosity patterns that researchers use to identify individuals. Further east, Gansbaai adds the Marine Big 5 — Cape fur seals on Geyser Rock, bronze whaler sharks, common dolphins and African penguins at Stony Point. Dyer Island takes its name from Samson Dyer, who collected guano there in the early 1800s; Shark Alley runs between it and Geyser Rock.
Sound carries the point better than sight. Breaching southern rights land with a report audible from the twelve-kilometre cliff path, which is why Walker Bay whale watching boat trips keep engines idle when a cow surfaces. Humpbacks pass through on longer migrations, and Cape gannets work the shoals overhead. A whale watching boat Cape Town tour from Hermanus is, in the end, a short passage into a recovering population's living room.
