Cornwall is fine. Just go slow and be prepared to back up. If you come to a passing place, slow down and see if anything is coming so you can pull in easily. A lot of the roads are fine but there are definitely some narrow bits.

Driving in Cornwall is often described as a "beautiful challenge" that requires patience and a specific set of skills. While the primary A-roads like the A30 are modern and efficient, once you head toward the coast or remote villages like St Ives or Port Isaac, the roads become notoriously narrow "single-track lanes" flanked by high ancient stone hedges. These lanes often require drivers to reverse into small passing places to allow oncoming traffic to pass, which can be stressful for those used to multi-lane highways. During the peak summer months, congestion is a significant issue, as the infrastructure was never designed for the volume of tourist traffic it receives. Finding parking in historic fishing villages is also a major hurdle, with many requiring you to park in "top of the hill" lots and walk down. However, having a car is essential for reaching the most secluded beaches and hidden gems like Kynance Cove or the Minack Theatre. For 2026 travelers, the advice remains: rent the smallest car possible, master your reverse gear, and allow double the time you think you'll need for any journey.
