Inverness - try the postcode IV1. The Eastgate Shopping Centre is IV2 3PP which may help.

The Links is a grassy area on the banks of the Cromerty Firth. Lovely views. Cruise ships come into Invergordon and sail right past The Links. A lady from a nearby house came to tell us that it was OK to stay the night.

Glenfinnan Viaduct (of Harry Potter fame). Parking at the visitors centre but quite tight especially for longer vehicles. This is not a large car park and you may find it is difficult to park. Our outfit is just under 6 m and we got in ok. Free parking for National Trust members.
