Travelled through Libya in middle feb and applied to the embassy in Tunis for the transit visa, luckily read this post first

I arrived Thursday night in Tunis from Italy and Friday morning went to the embassy, asked for the transit visa and after a while of this is not possible and you must fly in, I was asked to write a letter asking for permission to travel through Libya, I wrote probably the worst letter I’ve ever written. It contained all of the above (they will help you a bit so ask questions about what should be in it). The letter was written in English and addressed to the Libyan embassy. I did not get it translated in to Arabic, they also took a photocopy of my passport and I did not need to give them a copy of my bikes registration just included the reg number in the letter

To get your passport translated head for the French embassy in Tunis just off the main strip and there are 2 places near there that will do it for you very cheap 8 dinar £4 just ask around you can't really miss them rue du Yugoslav I think

returned to the embassy after 10 days not working days and was told to return in one week

applied 29th Jan, returned after 10 days 8th feb, got visa 15th feb

Its well worth it, it’s a fantastic country and everyone is very nice not like Tunisia and Egypt no hassle

The people in the embassy are a bit intimidating but once you have the visa you have been excepted and they will be very friendly, they were telling jokes and offering me coffee

once in the country to get through the checkpoints say that your travelling through Tunisia, Libya, Egypt or the other way around to explain what you are doing and say that you’re in transit, tell them you nationality (if from uk then say Britannia) the guards will go for Italia and French first. Tell them where you are going to stay the night (very important), some you will be waved through others are very difficult. I met 2 vans full of Romanians who helped translate for me through two of the worst checkpoints, basically they need to understand what you are doing

Some hotels do have signs in English and there are signs in Tripoli showing you the way, all have free wifi and are very good, basically look for the tallest building and that will be the hotel, There are petrol stations everywhere 10p per litre. restaurants are a little harder to find just stop at somewhere you think is one, it might be or it might not

For the British. The British embassy in Tunis does not translate your passport only provides the stamp and won't tell you where you can get it translated also no one knows where it is, it is a big waste of your time

Hope this helps

Forgot I got a 2 week transit visa
