Swim in three of Upolu’s cave pools and lava tube destinations on a full-day tour. Enjoy fresh and saltwater swims in Piula Cave Pool, To Sua Ocean Trench, and Vaiula Cave Pool.

Start your day with a swim in the freshwater spring pool sitting beneath a historic church at Piula Cave Pool. Swim 25 metres into the cave and sit on a natural ledge at the end. Experience a remarkable phenomenon that makes your submerged legs appear a tint of cyan blue.

Next, head to the To Sua Ocean Trench. Brave the steep descent into the trench and swim in the tidal waters. Stroll around the lovely gardens and gaze over the beautiful volcanic coast.

Stop at Vaiula Beach Fales for a delicious focaccia tuna sandwich lunch and snacks. Engage with the chief according to village custom before equipping everyone with a headlamp or torch in preparation for the tour of the cave pool.

Hike through the jungle to the hidden entrance of Vaiula Cave Pool (not far from the beach fales lunch spot). The journey through the 150-meter long lava tube is fascinating. After descending into the cave, encounter some nice horizontal sections and a minor talus slope, occasionally requiring one to bend down to avoid scraping one’s head.
Finally, arrive at the pool, where the water is absolutely pure and crystal clear. Swim 10 – 15 metres to where the tube dives underwater.

On the way home, stop to view Upolu’s highest waterfall, Papapapaitai Falls at 110 metres.
