Fodor's Expert Review Ana Te Pahu

A grove of banana trees marks the entrance to these underground caverns that once served as dwellings. Partly shielded from the blazing sun, a secret garden of tropical plants thrives in the fissure where the caves begin. Below ground is a passage leading to a second cave where the sunlight streams through a huge hole.  Bring a flashlight, and be careful of dripping water if it's rained in the past week.
