Grootbos Nature Reserve is about 1 ' hours from Cape Town overlooking Walkers Bay. One of the best locations for experiencing the 'Marine Big Five- southern right whale, bottle nose dolphin, Cape fur seal, great white shark and the African penguin. Of the 350 southern right whales that visit the southern coast, up to 160 make Walker Bay their home from June to December. The cliffs of De Kelders, offer the best land-based whale viewing in the world. Breaching, tail-slapping and lob-tailing, the whales make the bay a constant hub of activity. Watch spellbound as mothers, calves and energetic bulls come to within 98 feet (30 meters) of the rocky shoreline.
