Go to a reputable interstate motor park in Zaria. Major operators like GUO Transport, GIGM, or Peace Mass Transit might have booking offices or use the Zaria Central Motor Park. Alternatively, you might need to go to Kaduna's major parks (e.g., Mando Park) for a wider selection of direct buses to the Southeast.

Book your ticket for a luxury bus to Aba. Ensure you choose a direct bus to Aba. Confirm luggage policy and seating arrangements. Departures are typically early morning.

The bus will depart from Zaria, heading towards Kaduna, then Abuja via the Abuja-Kaduna Highway (A2). This segment is generally smooth.

From Abuja, the journey continues south on the A2, passing through Lokoja. Lokoja is a common rest stop for passengers to stretch, use restrooms, and buy refreshments. Expect a stop of about 20-30 minutes.

After Lokoja, the bus will proceed through areas like Okene, then potentially towards Agbor (using roads like F116 and Agbor road Main, A232), before heading to Onitsha. You will cross the impressive Second Niger Bridge, connecting Asaba to Onitsha.

From Onitsha, the bus will take the Onitsha-Owerri Road, passing through Owerri city. Expect some local traffic here.

Finally, the bus will continue from Owerri to Aba using roads like F229, A6, and Aba-Owerri Road, eventually merging onto the Enugu-Port Harcourt Expressway before reaching Aba city.

Arrive at the bus company's terminal in Aba, such as the Peace Mass Transit terminal, GUO/GIGM terminal, or the main Milverton Street Park. From there, you can take a local Keke (tricycle) or a taxi to your final destination in Aba.
