A perfect cone-shaped volcano that rises to 1770m, Kolombangara looms majestically on the horizon, due east of Ghizo island. It's a two-day hike to the top and back. It rises from a 1km-wide coastal plain through flat-topped ridges and increasingly steep escarpments to the rugged crater rim of Mt Veve. Logging has been a major activity, with Ringgi being the main settlement, on the south coast.
