If you only have 24 hours to spend in Inverness, we suggest starting your day by visiting Inverness Castle, which overlooks the River Ness. It's a quick visit, but offers stunning views of the city.
Next, head to the Inverness Museum and Art Gallery. This museum tells the story of the Highlands and has a great collection of artwork. Allow yourself 2-3 hours to fully explore the museum.
For lunch, head to The Mustard Seed, a restaurant located on the banks of the River Ness. The restaurant serves Scottish cuisine in a cozy atmosphere. Allow yourself at least an hour for lunch.
After lunch, take a walk along the River Ness and enjoy the beautiful scenery. A walk along the river will take approximately 1-2 hours, depending on your pace.
In the evening, take a ghost tour of Inverness. The city is rumored to be one of the most haunted in Scotland. Allow yourself 1-2 hours for the ghost tour.
End your day at Hootananny, a popular music venue that features traditional Scottish music. The venue is open until late, so you can enjoy music and drinks for as long as you'd like.
