Round Dingwall Walk
There is a lovely circular walk around Dingwall that is signposted, but for a good guide and what to expect please see - https://www.walkhighlands.co.uk/lochness/macdonald-monument.shtml
If you do not want to walk the entire 3.75 miles, you could walk down Tulloch Street from the High Street, turn right down the canal path at the bridge and walk down the canal path, over the train tracks to Ferry Point. You can then exit Ferry Point via the carpark onto Ferry Road, which will take you back to the High Street. This is an easy walk along flat paths and roads and for avid birdwatchers it is a great time to spot many birds along the canal and at Ferry Point.
