Transportation in Dalwhinnie

I would say it's double that, as you have to walk down Station Road before turning North on the old A9.
The bus service is limited to a school bus and one single Scottish Citylink service a day. There is little chance that one of those two or three buses a day will correspond with the infrequent train service. Most Citylinks bypass the village on the new A9, or only observe the station road end stop.
This is a tiny station and tiny village. There is no taxi rank. Any taxi would need to be pre-ordered, probably from outside the village.
So I'm afraid it's taxi or walk. The taxi would be an expensive option. Babysitting the luggage at the station is your best option. But I would advise walking down Station Road and doing the babysitting in the Loch Ericht hotel. The station is a bleak place to wait.

Dalwhinnie is a tiny place, while the distillery is outside the actual village the easiest way to get there is probably just to walk. It's not far.

By the way don't miss the plaque at the station regarding General Montgomery's visit there in 1944. He finalised plans for D day there.

Another piece of information is that the war memorial at the station road end used to be opposite the hotel, because the mother of one of the casualties owned the hotel, and she wanted to open the curtains and talk to her lost son each day, a true and poignant story. It was only finally relocated about 10 years ago.

Thanks for the responses; I should have looked at Google Earth before posting my question! I see that there's not much to Dalwhinnie. While walking is physically manageable for us, toting luggage and a chance of drippy weather could make for a less-than-ideal excursion. I'll check into tour options as well and see what I can find.

It might be worth giving the distillary a call and seeing if they could provide transport for you (at least in one direction). There may be an enhanced chance if your husband, plus the other person in your party who was touring, would consider the more expensive "Expressions Tour and Masterclass Experience" (currently £65pp).
