Wonders of Papua New Guinea
Highlights
One of the most exciting and mysterious lands in the world is Papua New Guinea. Here live diverse indigenous people speaking in 820 languages who have very diverse cultural traditions.
The country has a very rugged terrain and still to a large extent is covered with pristine rainforest. Up to this day, Papua New Guinea is poorly investigated, and here are expected numerous exciting geological, biological, and archaeological discoveries.
The most impressive wonders of Papua New Guinea could be its giant caves. Here are located also some of the largest sinkholes of the world, very impressive gorges, canyons, and cliff walls, as well as possibly the most powerful springs in the world. Papua New Guinea contains diverse volcanos, several geyser fields, hot springs, and other exciting landmarks related to volcanism.
The biological diversity of Papua New Guinea is very high and there are locations that contain a large amount of endemic species of plants and animals. Here live the largest butterflies in the world. There are exciting legends and reported sightings of cryptids – mysterious animals.
New Guinea is one of the few locations in the world with independently developed agriculture. Traces of ancient fields are seen here up to this day. Megaliths thus far have been found in Trobriand Islands. Diverse cliff paintings recently have been found in hundreds of caves in different regions of the country.

Travels in Papua New Guinea
This is the story of a young Englishwoman who set out to travel alone through the highlands, jungles, and rivers of Papua New Guinea. It is the remarkable tale of a two-year expedition that included an eventful two-week walk and a thousand-mile journey on a stallion (in a country where almost nobody knew what a horse was) during which Christina witnessed a tribal fight with bows and arrows and a pig-killing celebration. She was accosted by bandits, sank into swamps, fell through rotten bridges, and got stuck in a ravine. For the fourth stage of Christina’s journey, she bought a dugout canoe and spent four months paddling alone on the Sepik River and its tributaries.
