A morning at Eden on the River starts with the hush of a Pacific island dawn: the Rentapau River slides past a ribbon of volcanic rock and palms lean over the bank as if to listen. You meet your guide under a simple sign and follow a narrow farm track where the air already smells of damp earth, crushed vanilla leaves and ripe pineapple. The kava fields lie in neat rows—the “Noble” varietals recognized by islanders for their smooth, ceremonial quality—small plants guarded by woven screens to protect their tender stems from sun and wind.
