I know this route well but have only walked parts of it because I preferred to walk the John O'Groats Trail route via Munlochy and Culbokie on the Black Isle. The slow ways route would take c4.5 hours to walk. Most of it is pretty accessible and on tarmac road but, there is a steady climb up from Redcastle and a piece of rough track then up to the A835.. 3) North Kessock coastal walk - North Kessock, pub, toilets and one shop. Only an occasional bus service and hardly any on a Sunday but, a nice view across the Firth and a tarmacked road all the way along to woods at Redcastle then it becomes an uphill trek inland across to the main Inverness-Dingwall road. This is a busy A road and difficult to cross with fast traffic however, there are good tarmac pavements along the road for use by cyclists/ walkers. Not really pleasant walking though as exposed, uphill, often windy and big traffic thumping past you.. Personally, I wouldn't use this route if I wanted to go for a walk because there is a lot of traffic on the A835 and its fairly exposed in some places though, the Black Isle bridge is impressive and there are good views across the Firth and again later, towards the Highlands....
