Jambo! Welcome to Kenya. Your adventure begins with a welcome meeting at 6 pm. You can arrive at any time as there are no activities planned until this important meeting. If you arrive early, perhaps head out and explore the National Museum of Kenya, the Karen Blixen Museum or the highly recommended Bomas of Kenya, where traditional homesteads of several Kenyan tribes are displayed in an outdoor village.

Depart early for Mto wa Mbu in your overland truck. The trip includes a border crossing from Kenya into Tanzania, so be sure to have your passport handy. While you're on the road, there will be a stop at an ATM and a market or shop to stock up on any supplies you might need for the coming days. Arrive in Mto wa Mbu and acquaint yourself with this delightful small village – it's a fascinating snapshot of small-town African life, situated well off the tourist trail.

Get up early, put your camping and personal gear into a six-person jeep and head out for an excursion into the Serengeti via the Ngorongoro Crater. Enjoy a safari in the crater, spending 3 to 4 hours exploring this incredible, perfectly intact volcanic caldera. Watch for black rhinos, lions, leopards, elephants, impalas, zebras and hippos. The crater floor offers excellent game viewing all year round (some 30,000 animals live here) and the photo opportunities are unrivalled. Next, it's on to the wide-open plains of the Serengeti. Green after the rains, brown and burnt in the dry season, this is perhaps the quintessential image of Africa – the home of thousands of hoofed animals and fierce predators. Your campsite is within the Serengeti itself, so listen out for the sounds of nocturnal animals as you drift off to sleep.

Awake at dawn and embark on a game drive. You will head out while the animals are at their most active, then head back to camp for brunch at around 11 am. After spending the middle of the day relaxing, just like the animals do, head out again as the day begins to cool. You'll return from this second game drive in time for dinner. There's also the option of a balloon ride over the park this morning – in place of some of today’s game drives. If you have pre-booked this activity, you will be picked up before dawn and driven to the launch site. After a safety briefing, glide through the dawn, sometimes at tree height, getting some amazing photo opportunities. Sometimes you will ascend, getting an overview of the enormity of the plains and the early morning movements of the teeming herds. After landing, indulge in a five-star bush breakfast, then be returned to camp.

Rise with the sun and enjoy another game drive as you leave the Serengeti in your dust. Jump back into your overland vehicle and head for Mto wa Mbu.

Prepare yourself for a long travel day heading for the Usambara Mountains. Stretch your legs during a brief supply stop in Arusha, then jump back in the vehicle and watch the ever-changing scenery, read your favourite book or get to really know your fellow travellers. Your base will be Lushoto – an old German colony and home to the Wasambaa people. This highland town sits at approximately 1400 metres and this evening you'll camp in the grounds of one of the oldest hotels in Africa.

Explore the beautiful Usambara Mountains today – a lovely unspoilt area of Tanzania. Unlike the coast and the north, very few tourists visit this part of the country, so it has a freshness that can be hard to find elsewhere. As beautiful as the surrounding mountains and rainforests are, however, the real jewels here are the local people and villages. You'll experience some hospitality on a visit to some of the small local communities. From your base, you will take a walk out to the gorgeous Irente viewpoint. It's best to pack some water and snacks in a day pack for this trip. On your way back, visit a local cultural project where you enjoy a prepared lunch.

Leaving the mountains behind, travel further south to the coastal town of Kipepeo Beach in Dar es Salaam. Your camp is by the beach, so make the most of it – perhaps take a stroll along the shore after you arrive and settle in.

Drive to Dar es Salaam, then catch a ferry to Zanzibar. Filled with pristine white-sand beaches, winding cobblestone alleyways and fragrant bazaars, Zanzibar has had a colourful history – everything from slave traders to Arabian sultans and fruit exporters. The sight of traditional dhows sailing along the coast evokes what the island must have been like in centuries ago. Explore the many charms of Stone Town, the historic part of Zanzibar's main city, with a local guide. Sample some local food and gain insight into daily local life living on Zanzibar.
