West Papua's Two Marine Wonders
12 days, Kaimana to Sorong. Whale sharks at dawn, prehistoric mangrove fjords, and the world's richest coral reef — one continuous marine narrative. From $8,459/person.

Custom group
Peak Jan-Mar
Pioneered Since 2016
The crossing unites two ecosystems rarely on the same itinerary. Raja Ampat — 1,500+ fish species, 75% of the world's coral — is the biodiversity capital. Triton Bay, 200km southwest, hosts year-round whale sharks, pristine mangrove nurseries, and limestone formations that feel prehistoric.
The Kaimana-to-Sorong direction is superior: arrive fresh, acclimatize through Triton Bay's gentler sites, build to Raja Ampat's coral intensity by days 8-11. We've refined this rhythm across 10+ years.
Booking Window
Book in January or early February for the calmest seas. March gets choppier; by April, swell picks up. We've sent fewer than 2% of crossings back to port due to weather.

When to Cross
November
Shoulder. Variable winds. Excellent clarity. Fewer crowds. Photographers' pick.
December
Transition. Occasional rain. Algae blooms attract mantas. Underrated.
Jan-Feb
Peak. Calmest seas. Vis 25-40m. Whale sharks predictable. Books fastest.
Mar-Apr
Swell increases. Still productive. Prices drop 15-20%. Good value.
Insider
Bioluminescent dinoflagellates (night snorkel glow) peak during new moon phases. Check lunar calendar before booking. Coral spawning at Misool peaks late October / early November — night dives become mandatory.

350+ Guests' Worth of Knowledge
Photography
Second camera body + 4 backup batteries. Mai Mai whale sharks are fleeting — one failure, missed shot. Drone (DJI Air 3S) legal in West Papua. ND filters for harsh noon light.
Timing
Whale sharks most active 0600-0800 and 1400-1600. Bioluminescence peaks during new moon. Check lunar calendar before booking departure date.
Sea Sickness
Ginger supplements (2g morning of embark), acupressure wristbands, cabin amidships. Fresh air + horizon-watching works. By day 2, 99% acclimatize.
Logistics & Planning
No. We accommodate snorkelers and divers equally. Certified divers get deeper sites (20-35m); snorkelers explore shallows (3-10m). Both experiences are world-class. We offer on-ship PADI Open Water certification mid-trip (adds $400-600).
Valid passport (6+ months validity). Most nationalities qualify for Indonesia's Visa-Free Entrance (VFE) for 30 days. Confirm with your nearest Indonesian embassy. We provide visa guidance and letters of invitation from Juara Holding Group if needed.
All vessels carry medical kit (O2, AED, antibiotics, epinephrine). At least one crew member holds emergency medical training. Never more than 2 hours by speedboat from Kaimana or Sorong hospitals. Comprehensive travel insurance with evacuation is mandatory.
100% refund up to 90 days before departure. 50% refund 30-90 days. 0% within 30 days (exceptions for medical emergencies). Travel insurance typically covers last-minute cancellations. We've honored rebooks without penalty during past disruptions.
Absolutely. 3-5 day pre-trip packages in Sorong or Kaimana. Post-trip extensions to Lombok, Komodo (via Komodo Luxury), or Bali (via Bali Premium Trip) seamlessly arranged. Many guests add a Bali resort stay to ease back into time zones.
Unlimited. All vessels have reverse-osmosis systems producing 500+ litres daily. Fresh water for drinking, showers, and rinsing camera gear. Tanks refilled at ports. Crew reminds you to drink 3 litres daily — dehydration is the #1 preventable health issue.
