Although Inverness may be the gateway to the Scottish Highlands there is plenty to see and do in the city centre itself.
Inverness is blessed with many great pubs and especially live Scottish folk music. When I visit the city my go to is Hootenannys it has great atmosphere.
My general advice is if you are not hiring a car, then base yourself around the river Ness. I would also plan early for the summer month as Inverness can be popular during high season.
There is no uber in Inverness, if you wish to get a car pick up I have linked a local taxi company below.
