Cave Pool & Lava Tube Swims of Upolu

Exploring the Cave Pools & Lava Tubes of Upolu: An Authentic Samoa Adventure

If you’re dreaming of a day filled with unique swimming spots, lush jungle hikes, and spectacular volcanic scenery, this Cave Pool & Lava Tube Swims of Upolu tour promises just that. Organized by Samoan Highland Hideaway & Adventures, it offers a chance to experience some of Samoa’s most striking natural features in a compact, well-balanced day.

What we particularly love about this tour is the way it combines adventure and relaxation—you’ll visit multiple swimming holes, each with its own character, and get a taste of local culture along the way. The highlight is swimming in crystal-clear cave pools beneath historic churches and exploring an underground lava tube, all set against the backdrop of Upolu’s dramatic landscapes.

One possible consideration is that the tour involves some moderate physical activity—hiking, steep descents, and some bending in caves—so it’s best suited for active travelers without mobility issues. That said, it’s perfect for those who love discovering hidden spots and enjoy a mix of adventure and stunning scenery. This tour fits well for travelers seeking an off-the-beaten-path experience with a touch of local culture and natural beauty.

An In-Depth Look at the Tour Experience

Your day begins at the Visitor Information Center in Apia, where the group gathers and your guide provides an overview of what’s ahead. The meeting location is easy to find with the provided coordinates, and it sets the stage for a day focused on discovery.

First Stop: Piula Cave Pool

The first highlight is the Piula Cave Pool, a natural spring sitting beneath a historic church. We loved the way this spot combines spiritual history with natural beauty. The water is undeniably refreshing, and swimming 25 meters into the cave is a thrill—especially sitting on the natural ledge at the end. The water’s unique cyan hue in the submerged legs adds a touch of wonder, as one reviewer noted, “a remarkable phenomenon.” Expect about 40 minutes here, enough to enjoy the cool water and take some photos.

The Adventurous Main Attraction: To Sua Ocean Trench

The To Sua Ocean Trench is arguably Samoa’s most famous swimming hole. The steep descent into the trench is part of the fun, and once at the bottom, you’ll be swimming in tidal waters that are both invigorating and beautiful. The gardens surrounding the site add to the sense of being in a tropical paradise. Expect to spend about 1.5 hours here—you might want to allocate extra time if you’re a photographer or simply want to bask in the scenery.

Lunch at Vaiula Beach Fales

After the swim, you’ll stop at the Vaiula Beach Fales, a simple local spot where you can enjoy a focaccia tuna sandwich and other snacks. The relaxed atmosphere here offers a taste of village life, and it’s an excellent chance to interact with the local community. It’s a perfect break before the next adventure—exploring the hidden entrance to Vaiula Cave Pool.

Jungle Hike and Lava Tube Exploration

The highlight for many adventurers is the hike through the jungle to reach the hidden entrance of Vaiula Cave Pool. This part of the trip involves walking approximately 150 meters through a lava tube—a fascinating underground passage formed by ancient volcanic activity. You’ll need a flashlight or headlamp (provided by the tour) to navigate the dark, horizontal sections and minor slopes.

Swimmers will love the crystal-clear water inside the cave, where they can swim 10 to 15 meters to the point where the lava tube dives underwater. The experience of crawling through a volcanic tunnel and emerging into a pristine pool is unlike anything else in Samoa.

Scenic View of Papapapaitai Falls

On the way back to Apia, the tour makes a quick stop at the Papapapaitai Falls, the highest waterfall on Upolu at 110 meters. Although only a brief viewing—about five minutes—it’s a great photo opportunity and a chance to appreciate Samoa’s powerful volcanic landscapes.

Closing the Day

Returning to the Visitor Information Center, you’ll carry with you a sense of having seen a side of Samoa that most travelers miss—wild, beautiful, and full of surprises. The day’s highlights are well-paced, with enough time at each spot to enjoy without feeling rushed.
