A person from any of the ECOWAS countries do not need a visa to cross any land borders in the ECOWAS sub region. You may only be asked to show a proof of a yellow fever vaccination especially if you request for a visa stamp in your passport booklet at the border.
Contrary, a non ECOWAS citizen requires a visa to enter into any of the countries within the sub region. This is no exception to entering Lome, Togo from Ghana through Aflao. You need to apply for an e-visa for Togo through their online e-visa application portal via the link below.
Coming from Ghana through Aflao to Lome, Togo.
At the Ghana side of the border, bring out your passport and yellow fever vaccination card to show at the Ghana immigration office (light and deep green colored) on your left hand side after the car park for exit booking and stamp duties.
Once finished at the Ghana side, walk across the street to the right side to the Togolese post of the border for your e-visa in your passport to be checked. You will be given a sheet of paper to detail your personal information and purpose of visiting Togo. You may sometimes meet a lot of queue during the Togo e-visa scrutiny so have some patience until you are done then you leave. You are not require to pay any money during the passport review even though some of the Togolese officers may ask you for money (dash or tip) sometimes. If you are finished filling out the white paper form, add your passport and give them back to the officer behind the counter who initially attended to you. If the office sees that all is well with your information your passport booklet will be given a Togolese entry stamp and as well welcome you to Togo. And do not forget to take back your passport and yellow fever vaccination card before leaving the counter.
