Many coastal car parks in Cornwall prohibit overnight parking or have height barriers. However, the county has a growing network of dedicated motorhome aires, CLs, and Britstops offering legal overnight options. Some pub car parks welcome motorhomers by arrangement. Always check signage and restrictions before settling in for the night.

Service points with fresh water and waste disposal are available at most campsites and several motorhome aires across Cornwall. Public facilities are more limited. The Caravan and Motorhome Club maintains a directory of disposal points. Plan to service your vehicle every 2–3 days, especially if using CLs or aires with basic facilities.

May, June, and September are ideal — warm weather, manageable crowds, and good campsite availability. July and August are busy, particularly during school holidays when coastal roads and campsites fill quickly. Book well ahead for peak season. Early October can still be pleasant, and many campsites stay open until the end of the month.

The A30, A38, and A39 are well-suited to motorhomes of all sizes. However, Cornwall's famous narrow lanes — particularly approaching coastal coves and fishing villages — can be extremely tight for vehicles over 6 metres. Stick to B-roads and above for stress-free touring, and research specific routes before attempting smaller lanes. The north coast B3276 is scenic but narrow in sections.

Cornwall is one of England's pricier motorhome destinations in peak season. Commercial campsites charge £25–50 per night in summer, while CLs offer better value at £10–15. Motorhome aires range from £15–20. Fuel, food, and parking add to costs. A comfortable week-long tour budgeting £50–70 per day (including pitch fees and fuel) is realistic for a couple.

No — motorhomes cannot be taken to the Isles of Scilly. The Scillonian III passenger ferry from Penzance does not carry vehicles larger than bicycles. However, you can park your motorhome at Penzance harbour (check for overnight restrictions) or nearby campsites and take the ferry as a foot passenger for a memorable day trip or overnight stay on the islands.

Padstow town itself has limited motorhome parking, with height barriers in the main car parks. Look for campsites and CLs within a few miles of town — the area around St Merryn and Constantine Bay has several good options. The Camel Trail cycle path connects to Padstow from Wadebridge (approximately 5 miles), making it easy to cycle in from a nearby pitch.
