By train
There are no trains to or within Yemen.
By bus
Some buses operating throughout the Arabian peninsula connect to Yemen. The buses are mostly air-conditioned and comfortable, although the fleet, sometimes contains old buses which may not be very comfortable to be on for several hour trips. Note that arriving from Oman can prove difficult, especially if you're trying to get to Sana'a. There are buses from Salalah to Sayu'n in Wadi Hadramawt and Mukallah on the Indian Ocean, but at the moment, tourists especially from non-Arab countries are not allowed to use public transport on roads linking the East and the West of Yemen: Mukallah - Aden and Say'un - Sana'a. The tourist have to take a plane in order to come from the west to the eastern part of the country.
By car
It is possible to cross the Omani-Yemeni border in a car, although the border posts are often difficult to negotiate. Crossing from Saudi Arabia in a car is substantially more difficult, as regulations for getting a car into Saudi are very intricate.
