The Serengeti of the Sea

So you’ve seen the lions, rhinos and other beautiful wildlife of the savannah; now brace yourself for the Marine Big 5: whales, sharks, dolphins, seals and penguins!

Gansbaai is one of the only places in the world that can offer this extensive range of marine wildlife and Grootbos, situated right on the doorstep of this aquatic wonderland, is perfectly positioned to be your host and guide.

A Safari Unlike Any Other

To offer you the best possible experience and ensure your safety, Grootbos has partnered with Dyer Island Cruises who share the same dedication to service excellence, conservation and education.

Join us on a purpose-built eco-friendly tour vessel led by experienced marine biologists and guides who will share their knowledge with you, with an emphasis on the welfare and conservation of the marine life.

Witness thousands of Cape Fur Seals basking in the sun on Geyser Rock; trawl along the infamous Shark Alley on the lookout for the magnificent Great White Shark; float alongside curious and enormous Southern Right Whales; admire the colonies of endangered African Penguins on Dyer Island and watch spellbound as Bottlenose Dolphins surf and breach in the wake of the boat. Besides the Big 5, you will also see an incredible variety of sea birds and breathtaking unspoiled scenery!
