Tonga Cave
A large limestone cave above Songsong on Rota, with formations inside.
Updated 3 September 2026
Tonga Cave sits on the slope above Songsong on Rota, a large limestone chamber with stalactites and columns and a wide mouth letting daylight well in, used as a shelter during the war and as a gathering place before and since. The floor is level enough to walk on and the chamber is big enough that its scale is the main impression. It is a short walk up from the village. Rota's limestone is riddled with caves of this kind, most of them far harder to reach than this one.
What's there
- The chamber - a large limestone space with a wide mouth.
- The formations - stalactites and columns through the interior.
- The daylight - the mouth letting light well into the cave.
- The shelter history - the cave's use during the war and since.
When to go
December to June is the drier season. The cave is accessible year round. The walk up is short in any weather.
What to expect
There is no lighting beyond what comes through the mouth. The floor is uneven in places. There is no interpretation on site.
Nearby
Songsong is below, and Wedding Cake Mountain is west.
