Travelling from South B to Westlands involves connecting Nairobi’s southern transport network with the Westlands–Waiyaki Way corridor on the western side of the city.
South B is relatively close to central Nairobi, but the journey to Westlands crosses between different public transport corridors. For a commuter unfamiliar with alternative connections, the easiest journey to understand is:
South B → Nairobi CBD → Chiromo → Westlands
The journey will usually involve changing matatus in or around central Nairobi before continuing towards Westlands.

How to Get From South B to Westlands by Matatu
For an unfamiliar commuter, the journey can be divided into two straightforward legs.
First leg:
South B → Nairobi CBD
Second leg:
Nairobi CBD → Chiromo → Westlands
The passenger first boards a Nairobi CBD-bound matatu from South B.
After reaching central Nairobi, the commuter transfers to a westbound service travelling through Chiromo towards Westlands.
The basic journey is therefore:
South B → Nairobi CBD → Chiromo → Westlands
The important part is understanding where the first vehicle terminates and how to reach the Westlands loading point.
Which Matatu Goes From South B Towards Nairobi CBD?
Route 11 is associated with the South B–Nairobi CBD transport corridor.
However, commuters should still confirm the destination and direction before boarding rather than relying entirely on the route number.
For a passenger continuing to Westlands, another useful question is:
Where does this matatu terminate in town?
Knowing the termination point makes it easier to plan the transfer to the second vehicle.
Is There a Direct South B to Westlands Matatu?
Passengers should not assume that a consistently available direct matatu connects every South B boarding point with Westlands.
The more dependable journey structure is:
South B → interchange → Westlands
For someone unfamiliar with alternative cross-city connections, Nairobi CBD provides the easiest interchange to understand.
A regular commuter may identify another connection that works better at particular times, but that should be based on actual service patterns and stage locations rather than road geography alone.
Why the Interchange Matters
South B and Westlands are not extremely far apart geographically, but Nairobi’s public transport network is organised around corridors and stages rather than simple point-to-point travel.
South B feeds towards central Nairobi from the southern side of the city.
Westlands is reached from central Nairobi through:
Nairobi CBD → Chiromo → Westlands
This means the commuter needs to connect the two networks efficiently.
The quality of that transfer can determine whether the journey feels straightforward or unnecessarily complicated.
Where to Board in South B
The most convenient boarding point depends on where the passenger is starting within South B.
A commuter should identify a stage with a suitable Nairobi-bound service.
Before boarding, confirm:
the destination
direction
and
where the vehicle terminates in central Nairobi.
For a cross-city trip, the best first matatu is often the one that produces the easiest onward interchange rather than simply the first vehicle heading towards town.
Changing Matatus in Nairobi CBD
Where the CBD is used as the interchange, the journey works as follows:
South B boarding stage
↓
Nairobi CBD-bound matatu
↓
CBD arrival stage
↓
walk to the westbound loading area
↓
board Westlands/Waiyaki Way service
↓
Chiromo
↓
Westlands
The South B matatu may not terminate at the same location where the Westlands service departs.
Passengers should therefore include the walking transfer when planning the journey.
For a wider overview of Nairobi’s major public transport loading points, see the Nairobi Bus Stations, Matatu Stages & Termini guide.
Nairobi CBD to Westlands: The Second Leg
After completing the transfer, the passenger needs a vehicle travelling west through the Chiromo corridor.
The journey follows:
Nairobi CBD → Chiromo → Westlands
Some suitable vehicles may continue beyond Westlands along Waiyaki Way.
This means Westlands does not necessarily have to be displayed as the vehicle’s final destination.
Before boarding, confirm that the matatu passes through Westlands and tell the conductor where you want to alight.
Where to Alight in Westlands
Westlands is a sizeable commercial district rather than one single public transport stop.
The correct drop-off depends on the passenger’s actual destination.
Before leaving South B, identify:
the destination building or business
nearest major landmark
and
the road or section of Westlands.
Tell the conductor the specific landmark where possible.
A well-chosen drop-off can substantially reduce the amount of walking required after reaching Westlands.
South B to Westlands Matatu Fare
Where the journey requires two vehicles, the total fare consists of:
South B → Nairobi CBD fare
Nairobi CBD → Westlands fare
The amount can vary according to:
time of day
operator
passenger demand
traffic conditions
and
peak or off-peak travel.
Fares vary and can change at any time.
For a daily commuter, the useful figure is therefore the combined cost of the complete South B–Westlands journey.
How Long Does South B to Westlands Take?
The complete journey time includes more than the time spent inside the two matatus.
It consists of:
waiting in South B
South B to CBD travel
walking between CBD stages
waiting for the Westlands vehicle
CBD to Westlands travel
walking to the final destination.
Traffic around Mombasa Road, the CBD approaches, Chiromo and Westlands can affect the journey considerably.
The interchange can also become an important source of delay during peak periods.
Morning Travel From South B to Westlands
South B is relatively close to central Nairobi, but morning congestion can still make the cross-city journey unpredictable.
For someone working in Westlands, reaching the CBD is only the first part of the trip.
The more useful measure is:
South B home/stage → Westlands workplace
A commuter should therefore account for the CBD transfer, waiting time and final walk when deciding when to leave.
Evening Travel From Westlands to South B
The return journey reverses the network:
Westlands → Nairobi CBD → South B
The passenger first boards a vehicle travelling from Westlands towards central Nairobi.
After reaching the CBD, the commuter transfers to the appropriate South B service.
Again, the Westlands vehicle may not drop the passenger at exactly the same location where the South B matatu departs.
Regular commuters should therefore learn both sides of the CBD interchange.
Could You Avoid Nairobi CBD?
Potentially.
South B’s position south of central Nairobi means there may be alternative ways of connecting towards the western side of the city.
However, an alternative should only be recommended when the actual public transport connection is known.
A useful interchange should provide:
a reliable South B service
a known drop-off point
a nearby Westlands connection
frequent onward vehicles
and
a meaningful reduction in journey time or cost.
A road route that appears shorter does not automatically translate into a practical matatu journey.
The Shortest Road Is Not Always the Best Matatu Route
This is particularly important for South B to Westlands.
Private vehicles may have several possible road combinations for crossing between the two areas.
A matatu passenger is constrained by:
where vehicles actually operate
where they load
where they terminate
and
where connecting services can be boarded.
Public transport journey planning therefore needs to consider the network, not simply road distance.
What to Check Before Boarding in South B
A passenger travelling across Nairobi should confirm:
Route → Destination → Direction → Termination point → Interchange
For the first leg, the objective is to reach a Nairobi arrival point that provides a manageable connection to the Westlands service.
For the second leg, the passenger needs a westbound vehicle passing through Westlands.
What a Daily South B–Westlands Commuter Should Establish
A regular commuter should eventually have a repeatable journey:
best South B boarding stage
↓
most useful CBD-bound service
↓
best interchange
↓
shortest practical walking transfer
↓
reliable Westlands service
↓
best Westlands drop-off
↓
short walk to workplace
The same information should be established for the evening return journey.
This is much more useful than simply knowing that two matatus are required.
Building Better South B to Westlands Commuter Intelligence
The journey becomes more valuable once its operational details are verified.
| Data field | Information to verify |
|---|---|
| South B boarding stage | Exact location |
| First route | Route/service |
| Operator | SACCO/company |
| Destination board | Exact wording |
| South B–CBD fare | Peak/off-peak |
| CBD arrival stage | Exact location |
| Westlands loading stage | Exact location |
| Transfer walk | Distance/directions |
| Westlands service | Route/operator |
| Second fare | Peak/off-peak |
| Westlands drop-off | Exact location |
| Destination landmarks | Best drop-off by destination |
| Alternative interchange | Whether it beats CBD |
| Peak journey time | Morning/evening range |
| Return journey | Exact stages |
| Last verified | Field-check date |
The highest-value improvement is establishing the exact CBD transfer between the South B arrival point and the Westlands departure stage.
Once that information is verified, the guide becomes a step-by-step commuter journey rather than simply telling passengers to “go to town and change.”
