The moment I descended into the warm, blue waters off Luganville's coast, I knew this wasn't going to be an ordinary dive. Twenty meters below the surface, the massive silhouette of the SS President Coolidge emerged from the blue haze – a 200-meter luxury liner turned troopship that sank during WWII after hitting an American mine. As I finned closer to this underwater giant, I realized I was about to explore one of the most accessible shipwrecks in the world, an underwater museum frozen in time since 1942.

The History and Legend of the Coolidge

Before strapping on my BCD and tanks, I spent an evening at Luganville's small maritime museum, absorbing the Coolidge's fascinating history. Originally a luxury cruise liner built in the 1930s, this massive vessel was converted to a troopship during WWII. Her final voyage came in October 1942 when, approaching Espiritu Santo harbor, she struck two American mines. The captain, realizing the ship was doomed, made the heroic decision to run her aground on the nearby reef, allowing nearly all 5,000 troops aboard to wade safely to shore.

What makes the Coolidge so special is how intact she remains. Unlike many shipwrecks that have been salvaged or deteriorated, this massive underwater time capsule still holds jeeps, medical supplies, personal belongings, and even the famous porcelain 'The Lady' statue that divers now touch for good luck. During my pre-dive briefing at Allan Power Dive Tours, the guides spoke of the ship with reverence – not just as a dive site, but as a war grave and historical monument.

💡 Pro Tips

  • Visit the maritime museum in Luganville before your dive to appreciate the history
  • Book with operators who emphasize respectful diving practices
  • Consider bringing a dive light even for daytime dives to see colors in the deeper sections

Preparing for the Dive Experience

Let's be clear – diving the Coolidge is not for beginners. With depths ranging from 20 to 70 meters and potential currents, this site demands Advanced Open Water certification at minimum, with many sections requiring technical diving qualifications.

I spent a week in Luganville, allowing time for multiple dives to different sections of the wreck. Most dive operators offer packages that include shore accommodations, equipment rental, and guided dives. I stayed at the modest but comfortable Deco Stop Lodge, where dive talk dominates every dinner conversation on their open-air deck.

Preparing my gear the night before each dive became ritual. My dive computer was essential for managing bottom time at varying depths. For capturing the surreal scenes inside the wreck, I brought my Insta360 Flow 2 Pro, which proved perfect for stabilizing my phone while filming the narrow corridors and cavernous holds without disturbing silt.

💡 Pro Tips

  • Minimum Advanced Open Water certification required, Nitrox highly recommended
  • Plan for at least 4-5 days to experience different sections of the wreck
  • Bring spare O-rings and basic maintenance tools as dive equipment supplies are limited in Luganville

The Lady and the Promenade Deck

Of all my dives on the Coolidge, the most memorable was exploring the promenade deck and encountering 'The Lady' – a porcelain relief of a woman riding a unicorn that once adorned the first-class smoking room. Our dive guide led us through a series of narrow passages, our bubbles dancing along the ceiling as we navigated the tilted corridors.

The wreck sits at a 45-degree angle, which creates a disorienting but fascinating experience as you swim through doorways that now function as hatches. Penetrating the ship's interior requires careful finning technique and excellent buoyancy control – disturbed silt can reduce visibility to zero in seconds.

I recorded the entire experience using my phone in an underwater phone housing mounted on my Insta360 Flow 2 Pro. The gimbal's stabilization was crucial in the tight spaces, allowing me to capture smooth footage even while navigating the ship's tilted corridors. The results were stunning time-lapse sequences showing how light filters through portholes, illuminating the ship's interior in ethereal blue rays.

💡 Pro Tips

  • Practice perfect buoyancy control before attempting interior penetration dives
  • Touch 'The Lady' for good luck, but remember this is a war grave – respect the site
  • Consider a guided night dive to see the wreck in a completely different atmosphere

Million Dollar Point and Beyond

While the Coolidge is undoubtedly Luganville's main underwater attraction, don't miss diving at Million Dollar Point – a surreal underwater junkyard where the US military dumped millions of dollars worth of equipment rather than sell it cheaply after WWII. Bulldozers, jeeps, and forklifts create an artificial reef that's now teeming with marine life.

Between dives, I explored Luganville's modest town center and ventured into the surrounding jungle to visit blue holes – natural freshwater springs perfect for cooling off. The local market offered fresh tropical fruits that became my post-dive recovery snack, along with coconuts cut open right before my eyes.

For longer surface intervals, I'd relax at my accommodation reviewing footage and making notes. My waterproof notebook proved invaluable for sketching dive plans and recording observations underwater, while my portable hard drive kept all my video footage safely backed up.

💡 Pro Tips

  • Allocate at least one dive day for Million Dollar Point
  • Visit the local market for fresh fruits and authentic Ni-Vanuatu cuisine
  • Rent a scooter to explore the island's blue holes on non-diving days

Practical Tips for Solo Travelers

Traveling solo to Luganville for diving presents unique considerations. The diving community here is tight-knit, making it easy to connect with other divers at lodges and dive shops. I quickly found myself part of an impromptu group of international divers sharing stories over Tusker beers each evening.

While accommodations range from basic to comfortable, don't expect luxury resorts. Most dive-focused stays offer simple, clean rooms with fans rather than air conditioning. I found my travel sleep sheet useful for the occasional place with questionable bedding.

Internet connectivity is limited and expensive in Vanuatu, so prepare for a digital detox. I used my evenings to journal and plan the next day's dives rather than scrolling social media. That said, having a local SIM card for emergencies is wise – you can purchase one at the small airport upon arrival.

Solo female travelers should note that while Vanuatu is generally safe, Luganville is still a developing area with limited nightlife. Most social activities center around dive lodges rather than public venues.

💡 Pro Tips

  • Join the communal dinners at dive lodges to meet potential dive buddies
  • Bring twice as much cash as you think you'll need – ATMs are unreliable
  • Pack essential medications as the local pharmacy has limited supplies

Final Thoughts

As my week in Luganville came to an end, I found myself reluctant to leave. The Coolidge had revealed only a fraction of her secrets to me. Each dive offered new discoveries – a medical supply room still stocked with bottles, a jeep perfectly preserved in the hold, or the eerie beauty of the ship's massive propellers.

This remote corner of Vanuatu offers something increasingly rare in our over-touristed world: an authentic adventure that combines historical significance with natural beauty. The technical challenge of these dives, combined with the historical weight of what you're witnessing, creates an experience that stays with you long after your logbook entries fade.

For the advanced diver seeking something beyond the typical reef experience, the SS President Coolidge represents diving nirvana – a massive, accessible wreck in warm, clear waters with visibility often exceeding 30 meters. It's not just a dive; it's a pilgrimage to one of scuba's most hallowed sites. ¡Qué increíble experiencia! Just be prepared: once you've dived the Coolidge, ordinary wrecks may never quite satisfy you again.

Million Dollar Point is worth a snorkel too if you need a break from the deeper dives. Incredible to see all that dumped equipment.

OMG your photos are AMAZING!! That shot of the Lady statue gave me chills! Been wanting to dive here forever and your post just convinced me to book for next year. Did you have a favorite room or section inside the wreck?

Thanks! The cargo holds with all the military equipment were fascinating, but swimming through the promenade deck was probably my favorite experience. It feels like you're floating through a time capsule.

How difficult is the diving here for someone who's only done warm, calm waters before? Thinking about planning a trip but nervous about currents and visibility.

Did it twice. Water's warm and visibility usually excellent. Very little current at the wreck. Perfect for intermediate divers.

Brilliant write-up, John! I dived the Coolidge last year during my Vanuatu backpacking trip and it was genuinely mind-blowing. The sheer scale of the wreck is impossible to convey in photos. For anyone planning to go, I'd recommend staying at least 5 days in Luganville to get multiple dives in - the wreck is so massive that each dive feels like exploring a different shipwreck altogether. The jeeps and military equipment are remarkably well-preserved. I used my dive light which was essential for bringing out the colors in the deeper sections, especially around the medical supplies area. Did you manage to see the mosaic floor in the first class dining room, John?

Thanks Frank! I did see the mosaic floor - absolutely incredible how well-preserved it is after all these decades underwater. Completely agree about staying for multiple days. I did 8 dives and still feel like I only scratched the surface.

This looks incredible! What level of dive certification do you need to explore the Coolidge? I'm only PADI Open Water certified and wondering if I'd be able to see the famous Lady and the lamp.

John Ortiz

Great question! You can see parts of the Coolidge with Open Water, but for the Lady you'll need Advanced certification as she's at 40m depth. Many dive operators in Luganville offer quick Advanced courses specifically for Coolidge visitors!

Thanks John! Might be worth getting my Advanced before the trip then. Can't wait!
