Where to See Hammerhead Sharks: 10 Best Dive Destinations (2026)
Few underwater encounters match the thrill of a hammerhead school gliding through blue water. These scalloped and great hammerheads are pelagic specialists, and the best places to see them are often remote liveaboard destinations.
This guide covers the best places to see hammerhead sharks while scuba diving, from Cocos Island and the Galapagos to Malpelo, Socorro, Layang Layang and beyond.
Where Can You See Hammerhead Sharks While Diving?
The 10 best destinations to see hammerhead sharks are Cocos Island (Costa Rica), Galapagos (Wolf & Darwin), Malpelo (Colombia), Socorro / Revillagigedo (Mexico), Layang Layang (Malaysia), Bimini (Bahamas), Sudan Red Sea, Rangiroa (French Polynesia), Alor (Indonesia), and Aliwal Shoal / Protea Banks (South Africa).
Peak hammerhead seasons vary by region, but most schools appear during cooler upwelling months when nutrient-rich water draws in baitfish and sharks.
Hammerhead Shark Diving Regions at a Glance
Hammerhead hotspots cluster around oceanic islands, seamounts and current-swept channels:
- Eastern Pacific: Cocos, Malpelo, Galapagos and Socorro for massive scalloped hammerhead schools.

- Atlantic & Africa: Bimini for great hammerheads; Aliwal Shoal and Protea Banks for ragged-tooth and occasional hammerheads.
10 Best Hammerhead Shark Dive Destinations (Detailed)
1. Cocos Island, Costa Rica
Cocos Island is the gold standard for hammerhead diving. Scalloped hammerheads school in hundreds at sites like Alcyone and Dirty Rock, often alongside mantas, whale sharks and silky sharks.
Best for: Experienced divers on liveaboard trips; season peaks June through November.
2. Wolf & Darwin, Galapagos
Wolf and Darwin islands sit at the northern tip of the Galapagos and rank among the planet's best hammerhead sites. Schools often number in the hundreds at The Arch and El Arenal, alongside whale sharks and dolphins.
Best for: Experienced divers only; strong currents and cold thermoclines.
3. Malpelo Island, Colombia
Malpelo is a remote seamount in the Eastern Pacific where hammerhead schools mix with silkies and occasional whale sharks. Liveaboard-only access keeps crowds low.
Best for: Pelagic lovers seeking Cocos-style action with fewer boats.
4. Socorro / Revillagigedo, Mexico
The Revillagigedo archipelago (Socorro, San Benedicto, Roca Partida) offers hammerhead schools, giant mantas and playful bottlenose dolphins. It is one of the Pacific's most rewarding liveaboard circuits.
Best for: November through May liveaboard seasons from mainland Mexico.
5. Layang Layang, Malaysia
This remote atoll in the South China Sea is famous for scalloped hammerhead aggregations during the March-to-May season. Clear blue water and steep walls add to the appeal.
Best for: Dedicated hammerhead trips; book early for peak weeks.
6. Bimini, Bahamas
Bimini is the world's premier destination for close encounters with great hammerheads. Winter baited dives bring these impressive sharks within metres of divers on sandy flats.
Best for: Great hammerhead photography; season runs roughly December through March.
7. Sudan Red Sea
The Sudanese Red Sea offers uncrowded liveaboard diving with seasonal hammerhead schools at sites like Sha'ab Rumi and the Umbria wreck area. Historic wrecks add variety between pelagic dives.
Best for: Adventurous divers combining hammerheads with classic Red Sea wrecks.
8. Rangiroa, French Polynesia
The Tiputa Pass at Rangiroa channels hammerheads, grey reef sharks and dolphins through strong tidal flows. It is one of the South Pacific's most exciting drift dives.
Best for: Drift diving enthusiasts; timing dives with incoming tides is key.
9. Alor, Indonesia
Alor in eastern Indonesia delivers hammerhead schools at sites like Kalabahi Bay and Pantar Strait, alongside pristine reefs and strong currents. It is a rising Indo-Pacific pelagic destination.
Best for: Divers who want hammerheads plus world-class macro and reef diversity.
10. Aliwal Shoal & Protea Banks, South Africa
Aliwal Shoal and Protea Banks off KwaZulu-Natal are famous for ragged tooth sharks, but seasonal scalloped hammerheads also pass through on migration. Protea Banks in particular delivers big pelagic action in blue water.
Best for: Advanced divers; hammerhead sightings are seasonal but reef shark action is year-round.

When Is the Best Time to See Hammerhead Sharks?
Hammerhead seasons depend on the destination, but cooler water and upwelling often trigger schooling behaviour:
- Eastern Pacific: Cocos, Malpelo and Galapagos peak from June through November.
- Mexico (Socorro): November to May is the main liveaboard window.
- Atlantic: Bimini great hammerheads arrive December through March.
- Indo-Pacific: Layang Layang peaks March to May; Alor is best September to November.
Liveaboard trips book months ahead for peak hammerhead weeks, so plan early for the best odds of large schools.
