With its vast coastlines and warm tropical waters, Thailand is a dream destination for underwater hunters. Spearfishing here offers an incredible opportunity to selectively hunt your own dinner while immersing yourself in the rich marine ecosystems of the Andaman Sea or the Gulf of Thailand.
But spearfishing in Thailand isn't just about grabbing a speargun and jumping in. You need to know where to go, when the water is right, and most importantly, you need the right freediving foundation.
Here is your ultimate guide to spearfishing in Thailand.
The Best Spearfishing Spots in Thailand
When evaluating locations, you are looking for underwater structures—pinnacles, drop-offs, and rocky outcrops—where pelagic fish hunt.
1. Phuket & The Andaman Coast (The Top Choice) The Andaman Sea off the west coast of Thailand is widely considered the best spearfishing region in the country. The water is deep, the visibility is excellent, and the currents bring in large pelagic species.
- Targets: Spanish Mackerel, Trevally, Barracuda, and Snapper.
- Key Spots: Offshore pinnacles and drop-offs around Phuket, such as the deeper structures near Racha Noi. Always stay strictly outside National Marine Park boundaries (including the Similan Islands) and protected zones—Racha Yai's main reef sites, for example, are effectively a no-take zone.

2. Koh Trat / Koh Chang Archipelago Located in the eastern Gulf of Thailand, near the Cambodian border, this area is wilder and less explored. The visibility can be unpredictable, but the fish life is abundant.
- Targets: Grouper, Cobia, and Queenfish.
3. Chumphon Pinnacles In the western Gulf of Thailand (northwest of Koh Tao), there are deep offshore pinnacles that attract massive schools of fish. Because these are deep and heavily exposed to currents, they are strictly for advanced spearfishers.
The Spearfishing Season in Thailand
Timing your trip is crucial.
- Andaman Coast (Phuket): The prime spearfishing season runs from November to April. During these months, the ocean is flat, and visibility can reach 30 meters, making it easy to spot pelagic fish in the blue.
- Gulf of Thailand (Koh Tao/Phangan): The best conditions are usually from March to September, opposite to the Andaman side.
The Essential Skills You Need
A common mistake beginners make is buying a speargun before learning how to freedive. Spearfishing is freediving. If you cannot hold your breath comfortably, equalize smoothly, or move silently, you will never see a good fish, let alone shoot one.
To be a successful and safe spearfisher, you need:
- A Solid Breath-Hold: You need enough bottom time to lie in wait (ambush hunting) or slowly stalk a reef.
- Silent Duck Dives: A splashy, noisy descent will instantly scare away every Spanish Mackerel within 50 meters. You must descend like a ghost.
- Perfect Buoyancy: You need to be neutrally buoyant at your hunting depth so you can hover motionless without kicking.
- Buddy Safety: Spearfishing increases the risk of shallow water blackout because hunters often push their limits—and many hyperventilate before diving. You must know how to rescue a buddy.
All of these fundamental skills are taught in the Molchanovs Wave 1 and Wave 2 courses. We highly recommend completing at least a Wave 1 certification before picking up a speargun.
The Law: Keep it Ethical
Spearfishing in Thailand is completely legal, but it comes with strict rules.
- It is strictly illegal to spearfish using scuba gear (you must be freediving).
- It is illegal to hunt inside any National Marine Park.
- Night spearfishing with lights is widely considered unethical and is restricted in many local areas.
