Brighton to Portsmouth Road Trip: Hidden Gems & Coastal Charms

The Brighton to Portsmouth drive follows the A27, a 47-mile coastal route that skirts the South Downs National Park.

Today, it's a ribbon of tarmac that reveals England's changing coastline—from the chalk cliffs of the Seven Sisters to the muddy inlets of Chichester Harbour.
