Mombasa is Kenya’s second city and its primary port — on the coast 480km southeast of Nairobi. A car hire from Mombasa opens the Kenya coastal circuit: the south coast beaches and Diani Beach, the Shimba Hills National Reserve (coastal forest with sable antelope), the Arabuko-Sokoke Forest north of Malindi (Kenya’s largest remaining coastal forest), and the eastern Tsavo East approach (Voi gate, 160km northwest of Mombasa). Coastal Kenya self-driving is a different experience from the highland and savannah circuits — different terrain, different wildlife, lower park entry fees at Shimba Hills, and roads through baobab forest and coral rag that feel fundamentally unlike the interior of the country.
Where to Hire a Car in Mombasa
Mombasa Moi International Airport (HKMO) has hire car desks in the international arrivals hall (Avis, Budget, and several local operators). Alternatively, Mombasa hire companies in the CBD (city centre) offer direct delivery to hotels on the north or south coast on request. The airport pick-up is convenient for visitors arriving by air from Nairobi; the CBD collection is practical for visitors staying in Mombasa town. Rates are comparable to Nairobi for the same vehicle category — Hilux or RAV4 at USD 80 to 110 per day, Prado at USD 130 to 160 per day.
South Coast Circuit: Diani and Shimba Hills
Cross the Likoni Ferry from Mombasa island to the south mainland (vehicle ferry, KES 100 per vehicle, runs continuously — 30 to 90 minute queuing at peak times). From Likoni, the B8 highway runs south through Ukunda to Diani Beach (50km, 45 minutes after ferry crossing). Diani is Kenya’s premier south coast beach — 20km of white sand and coral reef. Continue south from Diani on the C106 to the Shimba Hills National Reserve gate (Kwale gate, 30km from Diani, 30 to 40 minutes). Shimba Hills entry: KWS rate USD 26 per adult, KES 700 per vehicle. The reserve is coastal forest on a highland plateau — the sable antelope (large, curved-horned antelope) is Shimba Hills’ signature species and is found nowhere else in Kenya. Elephant and forest birds (Fischer’s turaco, spotted flycatcher, Narina trogon) are additional attractions.
North Coast Circuit: Malindi and Arabuko-Sokoke
From Mombasa north: cross the Nyali Bridge (no ferry, north coast is mainland connected) and drive the B8 north highway through Kilifi to Malindi (120km, 1.5 to 2 hours). The Arabuko-Sokoke Forest Reserve is adjacent to the Malindi road — a KWS-managed forest reserve with entry at the Gede gate (near Watamu, 15km south of Malindi). Arabuko-Sokoke is Kenya’s most important coastal forest for endemic birds — the Sokoke scops owl (only in this forest globally), Clarke’s weaver, Amani sunbird, and Sokoke pipit are all found here. Birdwatchers visiting Kenya specifically for coastal endemic species consider Arabuko-Sokoke essential; wildlife photographers will find the forest light and the endemic species challenging but highly rewarding. Forest entry: KES 600 per adult.
Mombasa to Tsavo East (Voi Gate)
Tsavo East is accessible from Mombasa via the Mombasa-Nairobi A109 highway north — the Voi gate turn-off is 160km from Mombasa (1.5 to 2 hours). Tsavo East’s open red lava plains, very large elephant population (herds of 40 to 200 individuals), and the Galana River are accessible from this gate. The Aruba Dam (40km inside the gate) is the most reliable wildlife concentration point in the afternoon dry season — elephant, buffalo, hippo, crocodile, and lion gather at the permanent water. A Mombasa-based Tsavo East day trip (Voi gate, 3 to 4 hour game drive, return to coast) is feasible, though an overnight in the park produces a more complete experience.
