Historical sites, rock art painting and community life are to be found throughout most areas. The state is largely untouched by western development with countryside ranging from rugged, coastal wetlands to the dry, red desert centre. Distances are considerable and roads are limited. Although most of the popular attractions are reachable via sealed roads, some attractions require 4WD for access. The less adventurous visitor may wish to consider using tour organisations as this is a part of the world in which local knowledge can be important.
Many areas are sacred sites and permits are required before entry.
The northern end of the state, commonly known as the Top End, is dominated by wetlands at the foot of an escarpment. The wet season pours vast amounts of water over the escarpment which then spreads across the Kakadu National Park and Arnhem Land. The wet season has a major influence on activities and the surrounding environment. Above the escarpment the land stretches away into the Tanami Desert in the west and Barkly Tableland in the east before its transition into the dry, red Simpson Desert in the south. Like most of Australia, the Northern Territory is big.
