Train vrs. Airline from Munich to London

As much as I like to favor train travel, I think this is too much. It's an 11-12 hour journey with the need to consider the Eurostar check-in window, most of it on high-speed trains that don't offer much in terms of scenery.
It becomes worth doing if you are able to break the journey someplace, like the Middle Rhine valley, Brussels, Lille, Strasbourg, Paris even...

Yeah, no. The scenery, for the most part, isn't all that. Just fly. We've done the train on that route; although not all at once.

I’ve traveled the Stuttgart (DE) to Paris (FR) route and then on another occasion the Eurostar’s London to Paris route. Both were a first and satisfied my desires to experience high speed trains, to experience the once much hailed Eurostar, and to see/whizz by the countryside. I’ve also flown these routes as well as to/from other intercontinental European destinations.

We like to stay on the ground once we hit Europe, so we take trains but break long journeys into 4-5 hour segments. We consider it an opportunity to see new places, and it has worked out well.

If you go by train, you will take the Eurostar across the Channel from Paris, Amsterdam or Brussels. Pick one and then explore the options for an overnight stopover between there and Munich. There are many good ones.

Thanks for all the replies, we are not leaving until fall of 2024 so this gives us time to prepare and plan.

My husband has taken the train from Frankfurt to London twice, but Frankfurt has the high speed links going to Paris and Brussels where I think you change trains. It took about 7 hours and he really enjoyed it. Is it possible to start in Frankfurt instead of in Munich?

Add in the time it takes to get from the airports to the city centers (especially in London) and flying does end up taking a lot more time than it looks like, as well as the costs of getting to and from those airports.

I try to limit myself to four travel hours in a day whenever possible. In this case, it means the train trip is too long when I can make the same trip by air in less time and likely significantly lower cost.

Thanks for all the suggestions, I really appreciate it. Our trip will be centered around Berchtesgaden in southern Bavaria, with a side trip for a couple of days to the Black Forest region. So I'd probably keep Munich in the picture as a connecting hub I guess. After these three stops its on to London to visit friends before coming home.

My Munich to London flight is 2 hours and while I love train travel, there are many opportunities to ride trains in Germany/Austria. Trains can be done but riding a train for 13 hours sounds horrible and I'd spend the extra time in Munich or London as seeing the country from a train can be quite boring after a while. Not to mention the changing of trains.

Please clarify......do you plan to do this in one day?

For fun, I looked at the current schedule. You're looking at an 11 hour trip, give or take a few minutes, and three different trains. (The schedule will probably change by next year.)

That's a LONG day on a train. Personally, I'd split it into two or more days.
