KCA University is located along Thika Road, slightly opposite NYS Headquarters College.
From Bus Station, BS
If you are on the BS side, go to Ronald Ngala St. and board Githurai 45 buses available along the street. The buses include Nicco Movers, Virginia Coach, ZamZam, and others. You can board any bus heading to Githurai 45. Remember to tell the conductor to drop you at KCA University or Survey (Soonest you join Thika road). The campus is opposite where the bus will drop you.
Alternative: From CBD, commercial
If inside CBD, board Unified Poa buses available along Tom Mboya St. Also, Githurai 44, Kasarani, and Kahawa West buses (including Zuri and Marimba Investment) available opposite fire station can also take you there, but they are not the most viable option. Again, remember to tell the conductor to drop you at KCA University or Survey (Soonest you join Thika road).
From Ruiru, Thika, and Mt Kenya Region
To individuals coming from these sides, board any vehicle heading to town (Nairobi) and tell the driver or conductor to drop you at KCA University or Survey.
