Since South Sudan is located near the Equator in the tropics, much of its landscape consists of tropical rainforest. South Sudan also has extensive swamp and grassland regions.
The White Nile, a main tributary of the Nile River, also passes through the country.
The highest point in South Sudan is Kinyeti at 10,456 feet (3,187 m).
South Sudan tends to preserve the culture and ways of its northern counterpart, as time will tell if differences beyond political situations even exist.
South Sudan was once part of Sudan, but gained its independence in 2011.
English and Arabic (Juba Arabic) are the official languages of South Sudan, although Dinka is the most widely spoken language. Jur Modo, Nuer, Chollo/Shilluk, and Zande languages are also spoken there.
As South Sudan achieved independence only recently, the immigration rules are still prone to change. They have however instituted proper visas in your passport now, instead of the travel permits that were formerly used. The visas are issued for $100 at all border crossings and Juba International Airport. The length of the visas issued seems to vary randomly between 1 and 6 months. An invitation letter may be required depending on which official is at the desk on your day of arrival. The process can take 3 hours. If you do not have a local contact with official connections, it would be safer to get a visa before arriving in the country.
There are currently no direct commercial flights from outside Africa. So, changing planes is necessary; most airlines flying into Juba depart from Cairo (Egypt), Addis Ababa (Ethiopia), Entebbe (Uganda) or Nairobi (Kenya) Khartoum (Sudan) to/from where you should be able to manage flights to Europe, Asia or the Americas.

In the towns of South Sudan such as Rumbek and Juba, Kenyan and Ugandan beers are starting to appear in bars at inflated cross-border prices. Fresh fruit juices are available throughout Sudan. One of the local juices is "aradeab"(tamarind).
Starting in August 2012, Sudan and South Sudan have been fighting for Oil along the border of the two countries and traveling to the Sudan- South Sudan is very dangerous and highly discouraged! Please be very careful while you are traveling in this area, so you do not get injured or killed. DO NOT EVEN THINK ABOUT going across the gated and secured border into Sudan. This is highly dangerous as well. Updated october 2012, continued violent disruptions involving oil, journalist permits honored by Sudan are sporadically recognized as sufficient identification in South Sudan. Bribing is a possiblity, but does not gaurentee entry inbound to South Sudan.
