Piula Cave Pool: A Freshwater Gem Close to History
The first stop at Piula Cave Pool is a wonderful introduction to Samoa’s natural water features. Sitting beneath a historic church, this freshwater spring pool is just a few metres from the ocean, giving a peaceful vibe with ocean sounds as a backdrop. Swimmers can enjoy about 25 meters of water to explore, with enough natural light filtering in to make the experience less claustrophobic than typical caves.
One reviewer mentions how the submerged legs appear tinged with cyan blue once eyes adjust—a visual effect that’s both surreal and captivating. The natural ledge at the end of the cave offers a perfect spot to relax or take photos. The 40-minute stop includes entry fees, so you can focus purely on the fun.
To Sua Ocean Trench: Samoa’s Most Famous Attraction
Next up is the iconic To Sua Ocean Trench, a must-see for any visitor. The steep descent into this huge volcanic crater is part of the adventure, and once inside, you’ll swim through tidal waters in a 30-meter tunnel to reach a smaller, secondary trench. The experience is both exhilarating and scenic, with lush gardens and dramatic views over the volcanic coast providing plenty of photo opportunities.
The review highlights how the site’s popularity is justified, describing it as “unquestionably the nation’s most renowned destination.” The guide’s local insights help you navigate the steep steps safely, and the tranquil setting offers a perfect break from the more intense cave adventures.
Tafa Tafa Beach: A Relaxing Lunch Spot
After a morning of swimming and sightseeing, the tour offers a well-earned break at Tafa Tafa Beach. Here, you’ll enjoy a simple but tasty focaccia tuna sandwich roll, complemented by seasonal fruit and snacks. The quiet, less crowded environment is excellent for relaxing, and the guide takes time to engage with local chiefs, adding a touch of cultural respect.
Vaiula Cave Pool: A Hidden Lava Tube
The highlight for many, according to reviews, is the short jungle hike to Vaiula Cave Pool. The entrance is discreet, and the journey through the 150-meter lava tube is fascinating. As you descend, you’ll navigate horizontal sections, occasional head-scraping spots, and minor talus slopes that require bending down—an adventure for the physically capable.
Once inside, the water’s clarity amazes visitors, described as “absolutely pure and crystal clear.” Swimming 10-15 meters into the underwater dive spot offers a thrill and a chance to connect with Samoa’s volcanic geology. The free entry makes it a fantastic value, especially for those who love exploring hidden natural features.
Papapapaitai Falls: A Scenic Final Stop
The last sightseeing stop is a roadside view of Papapapaitai Falls, a dramatic 110-meter cascade. Visitors can snap photos and take in the lush scenery, making it an ideal way to conclude the active day. The free stop is brief but impactful, showcasing Samoa’s powerful waterfalls.
Return to Apia
