Hidden WWII Relics Along Bora Bora’s Coast

Nestled in the heart of French Polynesia, Bora Bora is renowned for its turquoise lagoon, overwater bungalows, and breathtaking landscapes. But beyond its postcard-perfect beauty lies a lesser-known chapter of history: its strategic role during World War II as a U.S. military base under Operation Bobcat. From 1942 to 1946, the island hosted thousands of American troops and eight massive coastal defense guns, remnants of which still captivate history buffs and adventurers today. Join us as we explore this fascinating slice of Bora Bora’s past and how you can experience it during your visit!

Operation Bobcat: Why Bora Bora?

Following the Japanese attack on Pearl Harbor on December 7, 1941, the United States entered World War II and urgently needed a strategic refueling and supply base in the South Pacific to counter Japanese advances. Bora Bora, with its deep Faanui harbor, single navigable pass (Teavanui Passage), and natural lagoon fortress, was the perfect candidate. In early 1942, Operation Bobcat brought approximately 4,300 to 7,000 American troops, including members of the 198th Coast Artillery Regiment from Delaware and the Navy’s Seabees (Construction Battalions), to transform the island into a vital military outpost.

The American presence left a lasting legacy. The Seabees constructed French Polynesia’s first airstrip on Motu Mute (now Bora Bora Airport), roads, a quay, fuel depots, and a seaplane base. These developments not only supported the war effort but also laid the foundation for Bora Bora’s modern tourism industry. Fortunately, the island saw no combat, as the Japanese never attacked, leaving the military installations, including the iconic coastal guns, unused but intact.

The Coastal Defense Guns: Silent Sentinels of WWII

To protect Bora Bora from potential Japanese invasions, the U.S. military installed eight 7-inch/44-caliber naval guns (often referred to as “cannons”) at strategic points around the island—south, east, north, and west. Operated by the 13th Coast Artillery Regiment (later the 276th Coast Artillery Battalion), these massive guns, each weighing around 15 tons and capable of firing shells up to 10 miles, were positioned to guard the lagoon’s entrance and key vantage points. Accompanied by bunkers and anti-aircraft defenses, they ensured the island remained a secure supply hub.

Today, all eight guns remain on the island, though some are more accessible than others. These relics, set against the backdrop of Bora Bora’s lush mountains and turquoise waters, offer a striking contrast between the island’s serene beauty and its wartime past. Visitors can explore these historical treasures, often perched at scenic lookouts with panoramic views of Mount Otemanu, Mount Pahia, and the lagoon.

Where to Find the WWII Guns

Here’s a guide to locating some of Bora Bora’s WWII coastal defense guns:

• • Faanui Village Trail: A short, 2-km hike from Faanui leads to a ridge with two cannons overlooking the Pacific Ocean. The trail offers stunning views and a glimpse into the island’s military history.

• • Fitiiu Point (Haamaire or Tuaihora): Near Anau, two cannons are accessible via a scenic walk, though you may cross private property—always ask permission from locals.

• • Point Pahua and Taihi (Popoti) Lookout: A 15-minute hike from a dirt 4×4 road near Taihi Point leads to two cannons and a former U.S. radar station with unparalleled views of the lagoon and motus. Look for an orange-painted metal post marking the trailhead.

• • Matira Point: The two cannons here are the most challenging to reach, set in thick jungle high on the mountainside. A strenuous climb is required, and a guided tour is recommended due to the terrain and private property concerns.

Tip: Four of the eight cannons are accessible by 4×4 vehicle, making guided tours a convenient option. The remaining two at Matira require significant effort, so they’re best for fit adventurers or those with a guide. Always respect private property and seek permission when necessary.

Exploring the Guns: Tours and Tips

For an immersive experience, join a 4×4 sightseeing tour to visit the cannons and other WWII sites. These tours, offered by operators like Moana Adventure Tours, combine history with adventure, taking you through the island’s rugged interior to viewpoints like Faanui Canon and Amanahune Bay. Knowledgeable guides share stories of Operation Bobcat and its impact, often blending in Polynesian culture and visits to fruit plantations or local craft workshops. Expect a bumpy but exciting ride

Alternatively, hiking enthusiasts can explore independently, but be prepared for steep trails and potential mosquito encounters. Wear sturdy shoes (no flip-flops!) and bring water. Some sites, like the Faanui cannons, are relatively easy to reach, while others, like Matira, are more demanding. Check with your hotel or local operators for guided hikes or directions, and always verify access with landowners.

The Lasting Impact of the American Presence

The American presence during WWII transformed Bora Bora. The infrastructure—roads, the airstrip, and the quay—paved the way for the island’s tourism boom, starting with the opening of Hotel Bora Bora in 1961 and the iconic overwater bungalows in 1970. The cultural exchange was equally significant. With up to 6,000 troops stationed at a time, interactions between GIs and locals led to lasting connections, including over 150 recorded births from relationships between American soldiers and Polynesian women. These stories inspired James Michener’s Tales of the South Pacific, which popularized Bora Bora as a romantic destination.

Today, efforts are underway to preserve this history. The BOBCAT Tourist Center and a new museum at Le Bora Bora by Pearl Resorts aim to showcase the U.S. military’s legacy, while guided tours keep the stories alive.
