The national capital Port Moresby is situated 130 miles (209 kilometers) south of Sim.
And of course, there is more to Papua New Guinea than just Sim, so set aside a few days to delve into the region's attractions. Tekadu, lays 19 miles (31 kilometers) to the east, and Wau is located 25 miles (40 kilometers) to the south.
Get outdoors and make the most of Papua New Guinea's open-air markets.
Make sure you throw in walking shoes and join one of the fascinating guided nature walks and wildlife spotting tours.
Those who travel often understand that food is a great way to really get to know an area. Breadfruit (ulu) and also coconuts are commonly used as components in dishes here. Follow the hungry locals and order chicken pot or kokoda fish. Those who would like to try something else, should try saksak (dumplings made with sugar and sago), a lovely way to round out your Papua New Guinea culinary experience.
The 16th of September is Independence Day, so if you're lucky enough to be in Sim then, be aware that banks, business and some attractions may not be open as the country celebrates.
At the end of your stay in Sim, chances are you'll find yourself making plans to revisit this delightful destination.
