Between July and December, the Walker Bay whale sanctuary's coastline between Pearly Beach and Hermanus becomes alive with the Southern Right Whales - enabling the local tourism industry to offer viewing packages for the Marine Big Five from land, sea or sky. De Kelders is one of the best places worldwide to observe whales swim within a few meters off the rocky shore. Their blowing and grunting can be heard up to 2 km away at night. De Kelders is the northernmost suburb of Gansbaai and is located 19 km from the town of Stanford. It lies between Perlemoenbaai and the "Plaat" (part of the Walker Bay Nature Reserve which stretches up to the Klein River Lagoon between Stanford and Hermanus).
The “Plaat” is very popular amongst the fishermen as there are many fishing spots. To get to these spots, you need a 4 x 4 vehicle and as you drive to your preferred spot, you can enjoy the beautiful surroundings. Here you can become one with nature.
