If you're coming to Halkidiki from Bulgaria or transiting through it, the Kulata-Promachonas border is your main entry point. It's the most modern gateway between Bulgaria and Greece, operates 24/7, and processes thousands of vehicles every day. This guide gives you everything you need: realistic wait times, when to go, what to bring, and alternatives if you want to skip the queues.
📍 Basics
- Name: Kulata (BG side) / Promachonas (GR side)
- Operating hours: 24/7 (holidays included)
- Type: Internal Schengen border (Bulgaria and Greece both in Schengen since March 2024)
- Check type: Random — not systematic 100% checks
- Authorities: Greek Police (GR) + Гранична Полиция (BG)
- Lanes: 6 inbound lanes + 4 outbound
Bulgaria joining Schengen in March 2024 significantly reduced waits but didn't eliminate them entirely due to the high volume, especially in summer.

📜 What you need
Documents
- EU citizens: ID card or passport
- Serbia / N. Macedonia / Albania / Kosovo: Passport
- Children: Their own document (ID or passport), and if travelling without both parents, authorisation
- Driving licence in date
- Vehicle registration
For the car
- Bulgarian vignette: Mandatory to use motorways in Bulgaria. Buy online at bgtoll.bg before reaching the border or at a petrol station. Price: ~€7-15 depending on duration.
- Green card: Recommended to confirm your insurance covers Greece (all EU policies usually do)
- Warning triangle, hi-vis vest, first-aid kit: Mandatory in Greece
🚫 Common mistakes
- Buying the vignette at the border: 10-20% more expensive plus a wait. Buy online beforehand.
- Travelling Friday evening: The worst possible time. If you can, shift to Thursday or very early morning.
- Forgetting the green card: Even though it's not systematically checked, it's crucial in an accident.
- Not enough fuel: Fill up in Bulgaria (30% cheaper than Greece). There's a petrol station in Promachonas but they charge more.
- No cash: Carry €50-100 in leva or euros for tavernas/restrooms near the border.
🔄 Alternative borders (if Kulata is backed up)
If live data shows 2+ hours of wait, two alternatives:
1. Ilinden-Exochi (BG-GR)
30 km east of Kulata. Smaller border. Usually 5-15 minutes wait even in peak season. Good for travellers coming from Sandanski/Petrich.
2. Iliada
40 km further east. Much smaller. Ideal if you're in eastern Bulgaria (Burgas, eastern Plovdiv).
Real-world queue-skipping algorithm:
At July-August peak, use an app that shows live wait times (Waze, sometimes Google Maps). If Kulata >1.5 hours, divert via Ilinden or Iliada — you add 30-40 km but save 1+ hour of waiting.
🛒 Other tips
- Toilets: Both sides of the border, clean, free.
- Food: You can eat properly on the Bulgarian side. On the Greek side, there are tavernas in the first villages (Promachonas itself has 2-3 tavernas).
- Currency exchange: DO NOT exchange at the border — rates are very poor. Use an ATM in Serres or Thessaloniki.
- Mobile coverage: EU roaming is free as soon as you cross.
- Kids: Bring snacks and water — long waits are hard on them.
💡 What to do if you're pulled aside for a check
- Cooperate calmly, no attitude
- Present your documents when asked
- If it's a vehicle check (random), open the boot
- Usually takes 5-10 minutes
