I don't see any mention of flying into Inverness and then getting to the town. RS mentions by train, bus, or car. Is it apparent when we arrive at the airport where to get a train? Or is it better to get a taxi or some sort of transportation other than train? We will be arriving at the airport at 9:15 PM (21:15) so that may limit our options. Would be grateful for your experienced guidance! We're going in September 2023.
Take a taxi. It is a very small airport.
You will love Inverness.
jdill7, when you get your tour documents, one if them will be detailed instructions in how to get to the hotel via each available means. Very straightforward, very helpful.
At that hour, just take a taxi. It's not that expensive.
There is a taxi rank just outside of the terminal. It's a small airport, follow the crowd as it winds around the outside of the building. Seems to me we paid about 25£ for a trip into Inverness. You should not have any difficulty getting a taxi even at that hour.
As you asked about ALL modes of transport-

The last buses into town are a route #11 at 2127 (arrives 2202) and a route #10A at 2208, arrives 2229. Cost £6
The next and last train is at 2224, arrive 2237, cost £5.40
It won't take long to deplane and get out of the airport- it's a small airport and that Loganair flight should be an ATR42-500 aircraft so a maximum of 48 passengers.
Enjoy your Tunnocks wafer- which is Loganair's in flight catering.
I have flown many times from Inverness and have never seen lots of taxis at the rank outside the airport. I suspect you might do better getting the bus. It's cheaper and the details are given above by isn31c (who is a public transport expert).
Apologies to OP.
DH reminded me that we actually reserved a taxi through this company https://www.inverness-airport-taxi.co.uk. They followed our very delayed flights and there was a driver when we arrived after 22:00. You will be best guided by the forum's local experts.
