Tripoli -> Getting There
To and from TUNISIA
There is really only one border crossing between Tunisia and Libya, the one at the coast, and the most common way of transport, is bus. Many people make the trip in cars. There are no trains.
To and from ALGERIA
The border point, deep in the south of Libya, is presently closed for overland traffic, at least for tourists. In any case, the distance is too much and there are good roads only on the Libyan side, this would have been an option only for the toughest of travellers.
To and from NIGER
Crossing overland to Niger is possible, even if connections don't suggest this. Passage must be arranged through one of the country's tourist agencies. Travellers choosing this route should take precautions for the Tuareg rebellion. Getting from Niger to Libya is apparently not possible, as you will not be given permits to go through northern Niger.
To and from CHAD
Crossing overland to Chad is possible, even if this is an uncommon route. Passage must be arranged through one of the country's tourist agencies. Relations between the two countries should be fair enough now, after the last Libyan troops left the territory they occupied in northern Chad.
To and from SUDAN
There are lorries doing the trip between the two countries, but this takes time. And make sure your papers are OK, before setting off.
To and from EGYPT
Provided you have a visa, crossing the one border point to Libya, north at Sallum, should be easy, but prepare for a long wait. This journey is done either by bus, or by car. The exit fee payable to Egyptian officials is not more than US$0,50.
To and from MALTA
Erratic and extremely expensive ferries run between Malta and Libya. Fares are much cheaper when tickets are picked up in Malta, compared to Libya.
INTERNATIONAL AIRLINES
The international embargo on all air traffic on Libya, was lifted a few years ago. There are good connections from not only other Middle Eastern and North African nations, but even from some European countries. London is the best transit point for most travellers from other continents.
