Holy wow, this is sobering. You definitely should carve several hours out of your day to visit the museum and battlefield. Outlander fan or no, this is worth the time.
We took the bus out of Inverness, which made things so much easier. We actually hopped off one stop before the Culloden stop, because we wanted a chance to mosey past the moor. It was only a mile from the second-to-the-last stop to the visitor center, and it was a beautiful, sunny and mild day, so we were in heaven.
I didn't realize before our visit that the battlefield itself is a park, free to anybody who wants to visit and that it's dog-friendly. I love that.
The visitor center (I call it a "museum", in my head) is very well done, and chock-full of information and experiences. They laid the whole thing out so that you're able to get into the heads of both sides of the battle, with the same timeline providing movements across the divide.
It can get a bit loud in there, though, so it's sometimes hard to hear the audio presentations built into a lot of their experiences.
But, they provide way more information than I would've expected, which is a nice bonus. You can walk in the front doors not knowing anything about Culloden, and - if you give the museum the time it deserves - you can walk out an expert on all things political, battle and civilian-related.
The museum itself is quite immense, meandering from one wing to the other, culminating in a theater that provides a wrap-around video of a recreation of the battle. They don't pull any punches in that room, so if you're scared of loud noises, gore, or have very small children, I wouldn't recommend going in.
The star of the area definitely is the battlefield itself, though. (Pause at the double doors to snag a loaner umbrella, if the weather looks iffy. It definitely came in handy on our visit!)
There are several different paths, all detailed in the free maps available at the desk near the doors, and explained on the battlefield itself. We took the less crowded path at first, as everyone and their mother were walking towards the monument in the middle of the field.
Our first path took us towards the Clan Donald stone, which is way far away from the main monument, closer to the road. I think the path typically circles back around the outside of the battlefield, but on the day we visited, they had the path past the Donald stone closed off, so we had to turn around and head back in the other direction.
We decided to go towards the main monument at that point, passing by other clan stones on the way (of course the Clan Fraser stone had a worn path in front of it, with a few fresh flowers scattered around).
My husband and I walked every path we could that afternoon, and are still amazed at the scope of the battlefield itself. For me, reading about it (yes, in "Outlander") and seeing the references in the museum did little to prepare me for how huge the battlefield itself was. They have flags placed across the land, showing where the Jacobites lined up, versus where the British forces lined up. The distance between the two flags is incredible. How battles were fought - on a slushy moor in poor weather, with men in kilts and sandals running at fully armed ranks - is astounding. Definitely something you have to see in person to really absorb.
I am so glad we took the bus out to Culloden, and that we allotted half a day to the experience. You do get your money's worth if you take the time to reflect and review.
We took a ton of pictures, but I don't want to overwhelm the Yelp servers, so I'll only post a few.
