It may well be the largest migration on the planet: The annual run of millions of sardines along the east coast of South Africa’s KwaZulu-Natal Province stretches nearly nine miles long and almost two miles wide—so large it can be seen from space. There was a time when only pro scuba divers could drop in on the massive school, but now anyone can slip on a mask and fins and swim with the fish. Watch for whales, sharks, dolphins, and clouds of seabirds, all after their next meal. SEAL Expeditions tracks the moving shoals and can provide the gear (ten days, from $3,895 per person; sardinerun.com).
Nearly the size of Massachusetts and home to more wildlife species than practically any other park on the continent, Kruger offers the best DIY tour in Africa. Rent a car and plan for at least a week, starting from Skukuza in the southern section of the park and heading north to the Limpopo River. You’ll stay at simple (and affordable) rest camps operated by the national park service, where you can also stretch your legs on bush treks with armed guides—after all, this is still wild Africa (car rental from $35 a day, avis.co.za; two-person bungalows from $80, sanparks.org).
Unlike almost every other safari destination in Africa, this is one that can be seen on two wheels. Wilderness Safaris’ six-day mountain bike trip takes in the wildest, most rugged terrain in the country, including the Damaraland community conservation project and the Ugab riverbed. Imagine pedaling the world’s oldest desert, with elephants, rhinos, lions, and a 977-mile windswept Atlantic coastline tossed in. Plan ahead and book the trip for May and June—wintertime—to beat the heat (from $3,475 per person; wilderness-safaris.com).
Once regarded by many safari veterans as the finest destination in Africa, Zimbabwe is returning to the fold after years of economic and political turmoil. Few experiences on the continent measure up to paddling the Mana Pools Canoe Trail, which traces the lower Zambezi River and harbors pods of hippos and plenty of crocs. In this case, you are in the water hole, and the wildlife—buffalo, elephants, impalas, baboons, and the predators that stalk them—comes to you. Classic Africa, a specialist in the region, provides river guides and gear (four days, from $1,330 per person; classicafrica.com).
