Which way to go
The fastest route
The quickest route follows the A30 east from St Ives, joining at Hayle and continuing through Chiverton Cross before dropping into Truro via the A390. In light traffic this takes around 40 minutes and is by far the most reliable option year-round.
The scenic route
For a more rewarding drive, leave St Ives on the B3311 towards Nancledra and Penzance, then pick up the A394 through Helston and on to Truro via the Fal valley. This coastal-and-countryside loop adds around 20 minutes but passes through some of West Cornwall's prettiest villages.
Caravans and motorhomes
The A30 is the most caravan-friendly route, with wide dual-carriageway sections and easy overtaking from Hayle onward. Avoid the B3311 coastal alternative, which has narrow lanes and sharp bends ill-suited to towing.
