Koropun sits deep in the Papuan highlands, and the food here reflects that isolation in the most beautiful way. The Kimyal people who call this valley home have sustained themselves for generations on sweet potato — known locally as hipere — roasted over coals or packed into traditional earth ovens called bakar batu. Watching a bakar batu ceremony unfold, with hot stones, layered leaves, and whole communities gathering to eat together, is not just a meal — it's a window into an ancient way of life.

Beyond sweet potato, foragers bring in ferns, wild greens, and forest mushrooms that add earthy depth to simple highland cooking. Protein is precious here — smoked or roasted bush meat, river fish, and occasionally pork during celebrations. There are no restaurant menus to navigate, no trendy cafes to stumble into. Instead, hospitality is expressed through shared meals in family longhouses, where a wooden bowl passed your way is the warmest possible welcome a stranger can receive.

For visitors arriving via missionary aviation into Koropun's short highland airstrip, the experience of eating locally means embracing that generosity wholeheartedly. Bring your own supplies for variety, but never decline what's offered — a roasted hipere handed over with a smile carries more meaning than any meal you've paid for. The food here won't dazzle your palate with complexity, but it will absolutely move you with its honesty, its rootedness, and the extraordinary people who prepare it.
