B1 drive through Plum Valley and Charleston highlights Portland landmarks

A motor tour along Portland’s B1, the Buff Bay to Balcarres Road, tracks north from Cotton Tree—also called Cotton Tree Pen—toward Plum Valley in Portland Parish, offering a compact look at settlements and landmarks on that stretch.

The route runs with the Buff Bay River along the left side as drivers head toward Plum Valley. Entering the valley, Quawos Village sits to the left while Charleston Primary School stands on the right.

The road then reaches Charleston. Within a short distance on the right lies Charleston Cave. Further along on the same side is Charleston Gaspar All. A few metres beyond that point, Plumb Valley Cave can be found on the right.

Taken together, the sequence—river, village, school, town, and cave sites—maps how the B1 links Cotton Tree Pen to Plum Valley and Charleston for anyone tracing Portland’s north coast interior by road.
