Simplified Journey to Joska
The route can generally be understood as:
Nairobi → Eastlands connection → Njiru → Ruai → Kamulu → Kangundo Road → Joska
Some vehicles may use Jogoo Road, Outer Ring Road, Umoja or Kayole before joining Kangundo Road.
Identifying a Joska-Bound Matatu
Look for vehicles displaying:
- JOSKA
- MALAA
- KANTAFU
- Another destination beyond Joska
A vehicle travelling farther along Kangundo Road may stop in Joska, but passengers should confirm this before boarding.
Where to Board Joska Matatus
Joska-bound vehicles operate from Nairobi stages serving Eastlands and the Kangundo Road corridor.
Boarding locations can change. Ask specifically for Joska rather than requesting only Route 38 or 39.
If a direct service is unavailable, passengers may connect from Ruai or Kamulu.
Njiru
Njiru is an important residential and industrial destination along the eastern corridor.
Some vehicles terminate here. Joska-bound passengers should confirm that their matatu continues through Ruai and Kamulu.
Ruai
Ruai is a major public transport interchange on the journey to Joska.
Passengers may find direct Joska vehicles or transfer to services displaying Kamulu, Joska, Malaa or Kantafu.
When transferring, confirm the new fare and the location of the correct onward stage.
Kamulu
Kamulu is the last major commuter centre before Joska.
Some Kangundo Road matatus terminate in Kamulu. Passengers travelling to Joska should ensure the vehicle continues farther east.
Kamulu can also serve as a transfer point when direct Nairobi–Joska services are unavailable.
Joska
Joska is the principal destination covered by this guide.
The area includes residential developments, businesses, schools, farms and roadside commercial centres. Passengers should identify their exact stage, estate entrance or landmark.
Vehicles continuing beyond Joska may stop only along the main Kangundo Road corridor.
Direct Service or Multiple Vehicles?
Possible journey arrangements include:
Nairobi → Joska directly
Nairobi → Ruai → Joska
Nairobi → Kamulu → Joska
The most convenient option depends on the time, available vehicles and passenger demand.
A direct vehicle generally reduces transfer uncertainty, while a connection through Ruai may offer greater service availability.
Common Route Numbers
Services along the wider corridor may display:
- Route 38
- Route 39
- Route 38/39
- A destination name without a prominent route number
For longer journeys, the displayed destination is more important than the route number.
Travelling Beyond Joska
Passengers may find onward services towards:
- Malaa
- Kantafu
- Tala connections
- Kangundo
- Other communities along the corridor
Confirm whether Joska is the vehicle’s terminus or an intermediate stage.
Useful Connections
| Connection point | Onward travel |
|---|---|
| Njiru | Local residential and industrial areas |
| Ruai | Eastern Bypass and Nairobi connections |
| Kamulu | Local estates and Kangundo Road services |
| Joska | Malaa, Kantafu and other outer destinations |
| Kangundo Road | Metropolitan and regional connections |
Return Journey: Joska to Nairobi
The return journey generally follows:
Joska → Kamulu → Ruai → Njiru → Eastlands corridor → Nairobi
Passengers should confirm whether the vehicle enters Nairobi CBD or terminates at another interchange.
Morning services towards Nairobi can become crowded. Evening demand generally increases from Nairobi and Ruai towards Joska.
