Ultimate Guide to Outdoor Adventures on the Big Island of Hawaii: Hiking, Hunting, Fishing & More

The island of Hawaiʻi stands as the youngest and largest gem in the Hawaiian archipelago, earning its moniker “Big Island” with reason. Its vastness is nothing short of awe-inspiring, being nearly twice the size of all the other Hawaiian Islands combined. Such grandeur is matched only by the diversity it harbors within its boundaries.

As you traverse this enchanting land, you’ll encounter a staggering variety of climates, ranging from the lush Wet Tropical zones to the frigid Polar Tundra. This remarkable range is attributed to the presence of two colossal volcanoes, Mauna Kea and Mauna Loa, whose shielding effect and elevated heights contribute to the island’s exceptional climatic mélange.

Hawaiʻi Volcanoes National Park, a testament to the island’s geological wonders, invites exploration and discovery. Witness the captivating interplay of volcanic landscapes and feel the pulse of the Earth beneath your feet. The snow-capped peaks of Mauna Kea offer a striking contrast to the island’s tropical nature, creating a mesmerizing scene that captivates the senses.

Venturing further, you’ll be greeted by the lush valleys of the Hilo and Hāmākua Coasts, vibrant and abundant with life. The gentle embrace of these valleys instills a sense of tranquility that soothes the soul. Yet, even in its gentleness, the island retains its powerful essence, an unwavering reminder of nature’s dominion.

Punaluʻu Beach awaits you with its striking jet-black sands, an extraordinary sight that sets it apart from typical coastal landscapes. Here, you’ll marvel at the harmonious dance between the sea and the land, witness to the perpetual cycle of nature’s artistry.

In every corner of the island, from its verdant valleys to its fiery volcanoes, nature’s force is palpable, leaving visitors humbled and inspired. Each experience, whether exploring the geological wonders or simply basking in the island’s natural beauty, is bound to leave an indelible mark on your heart.

So, embrace the splendor of the island of Hawaiʻi in your own way, for it is a place like no other, where the power of nature reigns supreme, and its grandeur knows no bounds.

But let’s get practical — if you’re like our clients at Outdoors International, you’re not just here to admire; you want to engage with this raw landscape through hands-on outdoor pursuits. Here’s a breakdown of the top activities, with focus on hunting and fishing.

1. Hiking & Volcanic Exploration in Hawaiʻi Volcanoes National Park

This UNESCO site is non-negotiable. Trails range from easy lava walks to strenuous descents into craters like Kīlauea Iki. Expect steam vents, lava tubes, and occasional active flows (check current status via NPS.gov). Pro tip: Go at night for glowing lava views — it’s surreal.

Pair it with nearby Hilo-side rainforest hikes in the Hāmākua Coast valleys for waterfalls and dense jungle.

2. Summit Adventures on Mauna Kea: Snow, Stargazing & Extreme Contrast

Drive (or join a guided 4×4 tour) to the 13,800-ft summit for snow in a tropical paradise — yes, you can snowboard or just enjoy the view. Sunset here is world-class, followed by elite stargazing (world’s best observatories). Altitude sickness is real; acclimate properly and book a guided tour for safety/transport.

3. Fishing the Big Island — From Deep Sea to Shore & Spearfishing

The Big Island has legendary fishing, thanks to steep drop-offs close to shore.

• Deep Sea / Charter Fishing — Kona Coast is the epicenter for marlin (blue, black, striped), swordfish, mahi-mahi, tuna. Year-round action; summer/fall peaks for billfish. Book charters from Kailua-Kona.
• Shore & Kayak Fishing — Hit spots like Keauhou Bay or Kohanaiki for trevally (ulua), goatfish. Kayak launches make blue-water access easy.
• Spearfishing — World-class in clear Kona waters. Target reef species (parrotfish/uhu, trevally/ulua, goatfish) or pelagic like mahi from shore dives/kayaks. Best areas: North of Kona (avoid restricted MLCDs like Kealakekua Bay, Waialea Bay, Lapakahi). Regulations: No spearfishing at night for certain species (e.g., parrotfish); check DLNR for protected zones and bag limits — uhu restrictions March-May.

Always verify current regs on dlnr.hawaii.gov/dar.

4. Hunting on the Big Island — Feral Game in Rugged Terrain

Hunting here targets introduced species for population control — feral pigs, goats, mouflon/feral sheep. No axis deer on Big Island (that’s Lanai/Maui).

Key seasons (check DLNR for updates/lotteries):

• Feral Pigs — Year-round pig hunting opportunities in units; e.g., Unit A: Feb-May (weekends/holidays), archery/muzzleloader extensions.
• Feral Sheep / Mouflon — Archery: March-July in areas like Puu Anahulu/Puuwaawaa; muzzleloader/rifle: Aug-Oct. Tags via lottery/online.
• Game Birds — Pheasant, turkey, etc.: Nov-Jan (weekends/holidays).

Public areas (forest reserves) require licenses/permits; private ranches offer guided options. Terrain is tough — lava fields, elevation changes — so guided hunts are smart for safety/success.

Always: Hunter education cert required; check dlnr.hawaii.gov/recreation/hunting/hawaiiisland for exact units, announcements.

The Big Island isn’t a “relax on the beach” destination — it’s for those who want to challenge themselves against volcanoes, depths, and rugged hunts. The diversity rewards preparation.

My most memorable and rewarding experience.

This was my first guided hunt, and the outfitter was amazing. He was able to keep me motivated and encouraged to hold out for true trophies. I would rate him on an 11 on a scale of 1 to 10! I never thought Africa would be a reality for me. Thank you Outdoors International.
