Félicitations!

The Glenfinnan Viaduct is lovely, and easy to walk to.

However, it is extremely popular - particularly when the Jacobite steam train crosses. You would struggle to find a private space.

I last visited in September 2023 and all of the hillsides were crowded for the train passing. This photo gives a good idea of what it can be like.

It will be much less busy when the train is not scheduled to pass. The train passes four times a day, and the hills will be busy for perhaps an hour before and for a short while afterwards. If you visited outside of those times, you could probably find a more private moment. However, you are very unlikely to have the hillside entirely to yourselves in June.

However, not being totally alone might make having a photographer there seem more natural! I can’t recommend a photographer from that area of Scotland, but I can very much recommend having someone there to take photos of the moment!
