To efficiently explore Cornwall's attractions, renting a car is recommended. Car rentals from Newquay Airport, the nearest major airport to Cornwall, start at £20 per day. A fuel budget of £50 should also be considered, given the distances and hilly terrain. Some attractions require walking and/or boat travel.
If you have more time, consider a guided tour of the Cornish countryside to learn about the history and culture of the region in depth. If you have less time, it is recommended to focus on either the northern or the southern coast of Cornwall. Lastly, pack comfortable walking shoes and warm layers as weather can be unpredictable.
