At Londa, 6km south of Rantepao, you'll find an extensive (and very popular) burial cave below a massive cliff face; its entrance is guarded by a balcony of tau tau . Inside there's a collection of coffins, many of them rotted away, and bones lying either scattered or heaped in piles. A local myth says that the people buried here are the descendants of Tangdilinoq, chief of the Toraja. Mandatory English-speaking guides with oil lamps accompany all visitors through the cave.
If you’re thin, and don’t suffer from claustrophobia, squeeze through the tunnel that connects the two main caves, passing some interesting stalactites and stalagmites. Rantepao–Makale bemo will drop you off at the turn-off, about 2km from the cave. Visit in the morning for the best photos.
