Drottningholm Palace Tickets

Just to be sure there's no confusion: Drottningholm Palace is outside Stockholm, but the Royal Palace and Riddarholmen Church are in the city--potentially walkable from your hotel. There are indeed a bunch of components to the Royal Palace.

Of all the places you named, I've only been to Riddarholmen Church, so you'll need to wait for assistance from one of our Stockholm experts. I'm pretty sure, though, that Rick Steves rates quite a number of Stockholm sights as more appealing than the Royal Palace. Obviously, tastes can vary in such matters.

That helps a lot. I totally missed that since they are all on the same website. I will look at a map and all my notes again. Thank you!

As Acraven noted, these are different sites. I think there are more interesting sites in Stockholm than the Royal Palace or Riddarholmen Church, but it all depends on your interests and the time you have. I think Drottningholm is more interesting than the Royal Palace in Stockholm, mainly because of Drottningholm’s setting on the lake and the lovely grounds.

There are two ways to get to Drottningham:

The Stromma company operates a boat to Drottningholm which leaves from a dock called Klara Mälarstrand. The dock is a short walk from either T-Centralen or the Stockholm City Hall. From Slussen, you could travel by subway or bus to get to the dock. You could also walk there. The boat ride is a very pleasant (in good weather) and scenic journey on Lake Mälaren to Drottningholm and takes about an hour. Information on the boat is here:

You can also take the subway (tunnelbana) to Brommaplan and then a bus to Drottningholm. This is the faster route, but obviously not scenic.

I’ve visited Drottningholm multiple times and what I typically did was take the boat to Drottningholm and the bus/subway back to Stockholm.

In my one day of experience in July 2018, the boat was enjoyable on the way there but a mob scene on the way back and I wished I had known about and taken an alternative method back. I used the Stockholm Card so there was only one option for boat departure that was included. If you have the card, it may save you money, depending on what you see. I am not sure that this year it included Drottningham but I think it includes all of the other things you mentioned.

Yes the advantage of taking the bus/subway back is timing. The boat only departs hourly (and less frequently outside of high season) and if it is crowded you may have to wait for the next boat. The bus runs pretty frequently (every 10 minutes or so), so as soon as you finish up you can just head to the bus stop and get on the next departing bus.

Thank you all so much, this is exactly what I need to know.

We are planning to go to Drottingholm on August 22nd when we are in
Stockholm for several days. I read another post about buying tickets
in advance so I started looking at the website.

Which website?

I would appreciate any comments on what I have posted about the
various ticket possibilities, recommendations and direct experiences
anyone has had with this.

I'm not sure there is much to comment about. There are different options for ticket, choose the one that gives you entry to the things that interest you the most. Of the once mentioned, I think that Drottningholm might be the best place to see in my opinion, but others might have other opinions. It is a bit outside the city though so takes a while to get there. Going there by boat is not a bad place, but using the bus and metro to get back to Stockholm is a good choice as it will allow you to leave when you want and not be tied to the boat's departure time.

I also looked at transportation from Slussen station, which is nearest
to our hotel and it looks like around 45-50 minutes overall between
walking, Train and bus. I saw that another poster mentioned taking a
boat. Can anyone advise on whether one way or the other is preferable
or do one of each to and from?

That very much depends on where you are going.

And would there be a Stromma boat that leaves from the Slussen area?

No, the only boats that leave from Slussen are the ferries to Djurgården.
