PNG’s largest populations of tribespeople are found among the mountain valleys and rushing rivers of the Highlands. Surrounded by peaks, the pleasant town of Goroka has a “perpetual” spring-like climate, with warm days and cool nights year-round.
It’s also a great place for planning treks into the nearby jungles and caves or arranging village stays. For an adventurous hike, take the four-day climb up Mt Wilhelm, the highest peak in PNG at just over 4,500m. On clear days, you can see both the north and south coasts from the summit.
