A Nairobi-to-Mombasa one-way car hire is one of Kenya’s most practical self-drive formats for visitors who arrive by air at Nairobi (Jomo Kenyatta International Airport) and depart by air from Mombasa (Moi International Airport) — or vice versa. The one-way hire eliminates the need to drive the return leg (480km each way) and allows the full circuit to be used for new destinations rather than retracing. Not all Kenya hire companies offer one-way hire, and those that do charge a drop fee to cover the vehicle repositioning cost. This guide covers which companies allow one-way hire, the typical drop fee range, the A109 route between the two cities, and how to combine a Tsavo stop on the one-way drive.
One-Way Hire Drop Fees
Kenya hire companies that allow Nairobi-Mombasa one-way hire typically charge a drop fee of USD 100 to 250 per vehicle. The fee covers the cost of a driver repositioning the vehicle from Mombasa back to Nairobi after drop-off. Larger companies with Mombasa branch offices (Avis, Budget, Europcar) sometimes waive or reduce the drop fee when demand is balanced between the two locations. Smaller specialist Nairobi operators typically charge the full repositioning fee. Confirm the one-way fee at booking — some companies advertise the daily hire rate without mentioning the one-way surcharge, which then appears on the invoice at pickup.

The A109 highway between Nairobi and Mombasa is 480km and takes 6 to 7 hours of continuous driving. The road is mostly dual-lane tarmac in good condition, though some sections through Kibwezi and around Voi have single-lane sections with heavy truck traffic. Key points on the drive:
- Machakos junction (50km from Nairobi): Good fuel stop, avoid high-traffic Nairobi petrol stations if departing early
- Mtito Andei (240km from Nairobi): The Tsavo West gate turn-off, midway fuel stop (Kenya Total station at the main junction)
- Voi (320km from Nairobi): The Tsavo East gate turn-off, last major town before the coast descent
- Mariakani (430km from Nairobi): The road descends to the coastal plain, temperature and humidity increase noticeably
- Mombasa (480km): The Makupa Causeway into Mombasa island — heavy traffic at peak times (morning and evening rush)
Adding a Tsavo Stop on the One-Way Drive
The most natural addition to a Nairobi-Mombasa one-way drive is an overnight at Tsavo East or Tsavo West. The Voi gate (Tsavo East) is 320km from Nairobi — a 4-hour drive, leaving sufficient time to enter the park by midday, complete an afternoon game drive, overnight at the KWS campsite or a mid-range lodge, do a morning game drive, and exit for Mombasa by 10am (arriving Mombasa by noon). This structure gives a 2-day itinerary out of the one-way transit drive and adds significant wildlife value to what would otherwise be a transit-only day.
One-Way Hire from Mombasa to Nairobi
The reverse direction (Mombasa pickup, Nairobi drop) is offered by the same companies but may carry the same or a higher repositioning fee depending on fleet demand. Mombasa’s hire vehicle market is smaller than Nairobi — fewer companies, fewer vehicle types, and potentially less availability for specialist safari vehicles (Land Cruiser Prado, Land Cruiser 76). If you need a specific safari-capable 4×4, booking the Mombasa pickup from a Nairobi-headquartered company that allows Mombasa pickup is safer than relying on a Mombasa-only operator for vehicle selection.
A 4×4 is essential for circuits that include the Ngorongoro Crater descent (which requires centre differential lock), the Bwindi Impenetrable Forest approach road in wet season, or Kidepo Valley National Park. For circuits that stay on sealed national highways and well-maintained murram roads in dry season a capable 2WD can manage — but the Toyota Land Cruiser V8 GX with full 4WD and diff lock is always the safest and most reliable choice for any East Africa self-drive circuit.
You need a valid driving licence (plus an International Driving Permit if your licence is not in English), the COMESA Yellow Card insurance certificate, a cross-border authority letter from the vehicle owner for each transit country, and the vehicle registration document. Car Hire 4×4 Drive prepares all cross-border documentation for the specific countries on your circuit as part of the standard hire process — no separate arrangement needed.
Yes. Most East Africa self-drive circuits do not require technical off-road skills — the majority of driving is on sealed national highways or well-maintained murram park roads. The vehicle handover at collection includes a full demonstration of the 4WD system. If your circuit includes genuinely technical sections such as the Ngorongoro Crater descent or Bwindi wet-season approach, a car with driver can be arranged for those sections if you have no prior 4WD experience.
Book 4 to 8 weeks in advance for standard circuits. For July to August peak season and December to January, book 3 to 4 months ahead. If your circuit includes gorilla trekking, Uganda permits via UWA should be booked 2 to 6 months ahead and Rwanda permits via the RDB 3 to 9 months ahead — the vehicle booking should align with confirmed permit dates. See the How It Works page for the complete booking process and deposit schedule.
The Toyota Land Cruiser V8 GX is the standard recommendation for any circuit covering two or more countries, or any circuit including Tanzania (Ngorongoro requires mandatory 4WD with diff lock) or Uganda’s challenging approach roads. For Kenya-only or Rwanda-only dry-season circuits the Land Cruiser Prado is a cost-effective alternative. For groups of 6 or more passengers, the Toyota Hiace 9-seater safari van with pop-up roof is the most cost-effective per-person option.
