Armenia shares land borders with four countries, but only the northern route into Georgia accepts rental cars. The crossings with Azerbaijan and Turkey have been closed for years, and Iran does not allow rental vehicles. As a result, anyone asking about driving a rental in Yerevan across a border receives the same answer: take the M6 north through Dilijan and Vanadzor, cross at Bagratashen, and continue to Tbilisi.
The route in numbers
- Distance: about 250 km from Yerevan to Tbilisi.
- Time: 5–6 hours of driving plus 30–60 minutes at the border.
- Border: Bagratashen (Armenia) / Sadakhlo (Georgia).
- Road: the M6, fully paved and mostly two lanes. The central stretch through Dilijan and the Debed gorge is especially scenic; plan a café stop in Dilijan.
After Vanadzor the road descends steadily beside the Debed river. The crossing lies in a low valley, busy with trucks but generally efficient.
What the rental company must prepare
Driving a hire car across an international border requires advance paperwork. Two documents must be ready before departure:
1. Notarised power of attorney — issued in Yerevan in your name and specifying this exact vehicle. It costs roughly $150 and takes one to two working days. Request it when you book and mention “Tbilisi” or “Georgia”. 2. Green Card — the international insurance certificate valid for Georgia, arranged by the rental partner.
Carry both originals. Armenian officers examine the power of attorney; Georgian officers may request it as well and will sell you third-party liability cover for about $20. Pay on the spot and keep the receipt.
An Edinburgh guest who booked two weeks ahead noted “one-way to Tbilisi” at reservation. The documents waited in the glovebox at pickup. After leaving the airport and pausing for khachapuri in Dilijan, he reached Tbilisi by evening.
Round trip or one-way
Both options are available and the price difference remains modest.
Round trip Yerevan → Tbilisi → Yerevan. The standard choice. Return the car in Yerevan. Ideal when Georgia forms a short side trip from an Armenia-focused itinerary.
One-way Yerevan → Tbilisi. Offered by selected partners. A drop-off fee of $80–150 appears at booking. Useful if your return flight departs from Tbilisi or Georgia is the longer portion of the journey.
In either case, do not switch to one-way at pickup if you reserved a round trip. The permit records the agreed route; any change requires a fresh notary visit.
Practical timing
If Tbilisi is part of the plan from the start, collect the car at Zvartnots on arrival. The first day in Yerevan is easily walkable. Drive toward Sevan and Dilijan the next morning, then cross in the afternoon. Aim to finish border formalities before 18:00; later hours bring longer truck queues.
Bottom line
Yerevan to Tbilisi by rental car is a planned journey, not an impromptu one. Notify the partner two days ahead, pay for the permit and Green Card, and the rest is straightforward driving. Six hours on the road, a single document check, and you are across.
