Puna is a district on the Island of Hawaiʻi (Big Island), located on the windward (eastern) coast.
Derived from puʻu ("hill, mound, rise") + nominalizing suffix -na. Literally: "place of hills" or "spring/water source" (cognate with punawai = spring).
Puna is associated with Pele (volcano goddess) and Hiʻiaka. Traditional land divisions (ahupuaʻa) run mauka-makai (mountain to sea). The district embodies creation/destruction cycles—new land forms daily.
Visitors: Respect private property, stay on marked trails, heed vog (volcanic smog) alerts, don't approach active lava.
