To Sua Ocean Trench
Samoa’s most photographed swim, half an hour from your fale
To Sua is the one place on Upolu that guests ask about before they have even unpacked. A collapsed lava tube, roofed only by sky, with a ladder down to a pool of clear green sea water. It sits in the village of Lotofaga, about fifteen minutes west of our beach along the same coast road — which makes Lalomanu the natural base for seeing it early, before the day trippers arrive from Apia.
What to Expect
Before You Climb Down
The Trench
A collapsed lava tube opening in the ground, roughly 30 metres across and about as deep, with the floor flooded by sea water that pushes in and out through an underground channel. From above you look down onto a small green pool; at the bottom you swim in it.
The Ladder
The only way in and out is a long, steep wooden ladder. It is sturdy and there is a handrail, but it is one person at a time in each direction, and it is a climb rather than a step. If you are unsure on ladders, watch from the clifftop gardens instead — the view is the photograph everyone comes for.
Gardens & Coast
The trench sits inside a landscaped clifftop garden run by the village of Lotofaga. A short path leads out to the blowholes and the tide pools, where the Pacific breaks against black lava rock. Allow an hour for the trench and another for the coast.
Entry & Opening
A village entry fee applies, payable in cash at the gate, and opening hours can shift with the season. Ask at reception before you set off and we will tell you the current rate and hours for the day.
The Best Time to Go
Early morning. The light reaches the bottom of the trench, the water is glassy, and the tour coaches that run from Apia have not arrived yet. By late morning in high season it is busy, and the ladder queue is real.
Worth Knowing
There is no shallow end — the pool is deep throughout, so it suits confident swimmers only. Life jackets are provided on site, and there are changing rooms. Bring reef-safe sunscreen, a towel, water and a dry bag for your phone.
Getting There
Fifteen Minutes West, on the Same Coast Road
Turn west out of Taufua and follow the south coast road through Lalomanu and Vavau towards Lotofaga. The entrance is signposted on your left, with a car park and the village gatehouse where you pay. Ask us to arrange a driver if you would rather not drive — most guests are there and back before the breakfast table is cleared.
On the way you pass the Togitogiga Waterfalls, a freshwater swimming spot in the rainforest that pairs naturally with the trench on the same morning.
Pair It With
A Trench Morning, a Beach Afternoon
Swim To Sua early, stop at the waterfalls on the way back, and be on our beach by lunchtime. Afternoon is for the reef and a long swim; in the evening, sunset dinner at the communal table, and on Wednesdays and Saturdays, Fiafia Night.
To Sua FAQs
How far is To Sua Ocean Trench from Taufua Beach Fales?
About 15 minutes by car, heading west along the coast road towards Lotofaga village. It is a straightforward sealed road the whole way — no four-wheel drive needed, and easy to do before breakfast.
Do you need to book To Sua Ocean Trench in advance?
No. You turn up, pay the village entry fee in cash at the gate, and walk in. There is no online booking and no timed entry, which is another reason to arrive early.
Can you swim in To Sua Ocean Trench?
Yes — the pool is sea-fed and deep, and swimming is the point. You climb down and back up the ladder, so a reasonable level of fitness and confidence on a steep ladder helps. Life jackets are available on site.
Is To Sua suitable for young children?
The gardens and clifftop walk are fine for everyone, but the trench itself is deep water reached by a long ladder. Young children and weak swimmers are better watching from above, with one adult supervising while others swim.
What should we take to To Sua?
Cash for the entry fee, reef-safe sunscreen, a towel, water, water shoes if you have them, and a dry bag. Camera or phone in something waterproof, because the best photos are taken leaning over the rim.
