Scotland's Land Reform Act gives a general right of access, which extends to overnight parking if you're responsible about it. In practice, many popular spots now have restrictions. Be self-contained, don't park where signs prohibit it, and leave no trace. The tolerance drops significantly if people leave rubbish or waste.

Allow at least 5-7 days for the full 516-mile loop. The single-track sections on the west and north coasts slow you down considerably. Trying to rush it in 3 days means you'll spend all your time driving and miss the point of the trip.

Late May through September, peaking in July and August. They're worst near still water, in sheltered glens, and at dawn and dusk. A breeze keeps them away, so coastal and hilltop spots are usually better. Bring Smidge or Avon Skin So Soft and a head net.

You don't need a ferry at all if you cross the Skye Bridge at Kyle of Lochalsh (free, no toll). If you want to take the Mallaig-Armadale ferry, book ahead in summer. CalMac ferries are popular and motorhome spaces are limited.

Every opportunity you get. The rule of thumb is never pass a fuel station with less than half a tank. The A9 corridor has regular stations. On the west coast, Ullapool, Gairloch, and Kyle of Lochalsh are the key stops. Some rural stations are card-only or have limited hours.

The A-roads are fine. Single-track roads on the west coast are manageable in anything up to about 7.5 metres if you're comfortable with passing places. Longer than that and you'll struggle on routes like the Applecross pass (Bealach na Ba) or the road to Durness. Choose your route based on your vehicle length.
