Hawaii Handgun Hunting Regulations

Last Reviewed: October 27, 2026 Handgun Hunting: Restricted

Hunting Overview

Hunting in Hawaii offers a dramatic departure from the mainland experience, trading traditional woodlots for volcanic slopes and tropical rainforests. The island chain is a unique stronghold for non-native game mammals that have thrived in the isolation of the Pacific. For the handgun hunter, the primary draws are the free-ranging axis deer and the elusive mouflon sheep. Axis deer, particularly on the island of Lanai, are known for their wariness and incredible density, often found in the dry scrub and open plains known locally as the Serengeti. Meanwhile, the Big Island provides a rugged backdrop for hunting purebred mouflon and feral sheep across high-elevation lava fields where the footing is treacherous and the air is thin.

The terrain varies wildly from one island to the next. You might find yourself glassing steep, emerald-green ridges on Kauai or navigating the jagged, arid lava flows of the Mauna Kea slopes. This diversity means that your physical preparation is just as important as your marksmanship. The climate is generally tropical, with high humidity and warmth at sea level, but hunters heading into the mountains must prepare for freezing temperatures, driving rain, and intense winds. It is not uncommon to start a morning in a t-shirt and end it in heavy fleece as you climb several thousand feet in pursuit of game.

Public hunting opportunities are managed through a system of Game Management Areas (GMAs) and Forest Reserves. Standout locations include the Lanai Cooperative Game Management Area, which is legendary for its axis deer and mouflon populations, and the Mauna Kea Forest Reserve on the Big Island, where hunters can pursue sheep and goats in a truly alpine environment. The Na Pali-Kona Forest Reserve on Kauai offers some of the most visually stunning and physically demanding hunting in the world, with deep canyons and sheer cliffs. Whether you are chasing Polynesian boar through dense jungle or stalking goats on a seaside cliff, Hawaii provides a hunting adventure unlike any other in the United States.

Muzzleloading revolvers/smooth-bore pistols are barred when hunting without dogs. Seasons and permitted methods are set per island unit in HAR Ch. 123 exhibits, so hunters must check the exhibit for their unit. Blaze orange is required in most public hunting areas; hunting hours are one-half hour before sunrise to one-half hour after sunset.
