Kenya

With a flawless, long stretch of white-sand beach hugged by lush forest and kissed by surfable waves, it's no wonder Diani Beach is so popular. This resort town scores points with a diverse crowd: party people, families, honeymooners, backpackers and water-sports enthusiasts.

East Africa's most cosmopolitan city, Nairobi is Kenya's beating heart, an exciting, frenetic concrete jungle that counterpoints the untrammelled natural beauty to be found elsewhere in the country.

Mbita and Rusinga Island (connected by a causeway) are delightful and great places to draw near to Lake Victoria. Tiny, languid and rarely visited, they offer a glimpse of an older Africa – an Africa that moves to the gentle sway of the seasons rather than the ticking of a clock. This is the sort of place where schoolchildren abandon their classes to watch you pass by and old women burst into song at your arrival.

Welcome to the wilderness. Tsavo West is one of Kenya’s larger national parks (9065 sq km), covering a huge variety of landscapes from swamps, natural springs and rocky peaks to extinct volcanic cones, rolling plains and sharp outcrops dusted with greenery.

The Arabs called them the ‘Seven Isles of Eryaya’, while sailors called them a welcome port of call when en route to, or from, India. Hundreds of expats who've fallen irrevocably in love with these islands call them home, as do the Swahili, who trace the deepest roots of their culture to here.

Laid-back little Watamu looks out over the Indian Ocean and enjoys a blinding white-sand beach and a soft breeze coming off the water. It's a gorgeous slice of coastline and one that includes its own marine national park. As well as its natural endowments, great dining scene and relaxed village vibe, Watamu makes an excellent base from which to explore the nearby Gede ruins, Arabuko Sokoke Forest Reserve and the mangrove-fringed waterways of Mida Creek.

Nanyuki serves as a gateway to the Laikipia plateau, one of Africa's most important wildlife conservation areas. Despite being a market town, it is probably the most cosmopolitan city in the area outside of Nairobi, with its share of international tourists (here to climb Mt Kenya or to visit the myriad safari parks), British Army soldiers (there is a training facility nearby) and Kenyan Air Force pilots (this is the site of the country's main air-force base).

Lake Nakuru is among Kenya's finest national parks. Flanked by rocky escarpments, pockets of acacia forest and at least one waterfall, the park is gorgeous year-round and is home to both black and white rhinos, lions, leopards, hippos and endangered Rothschild's giraffes. Rising water levels in 2014 forced the park's famous flamingos to flee (although a small number had returned at the time of research), and the lake is now hauntingly surrounded by drowned trees.

Dream of Africa and chances are that you dream of the Masai Mara. This huge expanse of gently rolling grassland – specked with flat-topped acacia trees and trampled by massive herds of zebras and wildebeest – is the ultimate African cliché. But for once the reality lives up to the image and the Masai Mara, which comprises not just the famous reserve but also around a dozen community conservancies, several group ranches and numerous Maasai villages, is for many people not just the highlight of their Kenyan adventure but the very reason they came in the first place.

Spread over 68,000 sq km, yet never more than 80m deep, Lake Victoria, one of the key water sources of the White Nile, ranks among East Africa’s most important geographical features, but is seen by surprisingly few visitors. This is a shame, as its humid shores hide some of the most beautiful and rewarding parts of western Kenya – from untouched national parks to lively cities and tranquil islands.
