To Sua Ocean Trench, where Lotofaga’s lawn drops into the sea

On the south coast of Upolu in Samoa, To Sua Ocean Trench near Lotofaga turns a flat grassy plateau into a sudden drop of lava rock and clear sea water, a striking natural basin set a short distance from the shore. The name To Sua is widely translated as “big hole”, a plain description of the way the ground opens into a deep sea-filled trench below lawns and paths.The name To Sua

A sea-filled crater in a lava field

To Sua Ocean Trench sits in a lava field close to the village of Lotofaga on the south coast of Upolu, one of Samoa’s main islands, where past eruptions left dark volcanic rock and blowholes along the shoreline.lava field close to the village of Lotofaga The trench forms a large, steep-sided opening in the ground with sea water at the bottom that is linked to the Pacific Ocean through underwater passages in the surrounding rock, so waves on the coast move the water in the pool and connect the basin to the ocean beyond.linked to the Pacific Ocean

Guides and geological notes describe the trench as around 30 m (about 98 ft) deep, creating a substantial column of water beneath the lawns and paths at the surface.around 30 m deep The rock around the basin is largely volcanic basalt, part of the wider lava landscape that shapes this section of Upolu’s south-eastern coastline.volcanic basalt The result is a sea-filled crater framed by vertical walls, hanging vegetation and the pale strip of lawn at the rim.

Gardens, paths and the descent to the water

Above the trench, local families have developed lawns, paths and sitting areas that give To Sua Ocean Trench the feel of a tended garden perched over raw volcanic rock.paths, lawns and sitting areas From the grassy plateau, the ground falls away into the basin, and visitors stand at the edge looking down at a column of clear salt water that reflects the greenery above.

A wooden ladder fixed to the rock wall provides access from the rim to a small platform close to the surface of the water, a simple structure that has become a recognisable feature of the trench.a 30-meter deep swimming hole From this lower platform, swimmers enter the basin itself, which is enclosed by rock on all sides and shaded in places by plants growing from the walls. Nearby, a second opening connects to the main trench through underwater passages, part of the same collapsed lava structure that created the sea-filled pool.two large holes joined by a lava tube
