This pleasant 50 minute tour works its way from Gamla Stan to South Djurgården, through a seldom-used canal, then back around Djurgården, finishing the round trip just outside the Grand Hotel. Headphones are provided with multi-channel tour narration options in several different languages. There are also special channels for children in both Swedish and English. Know it all about Stockholm? There's a special channel for locals, too.
Boats depart hourly starting at 10:30, supposedly continuing to 19:30 May-August (the day we took it, the last boat was at 18:30. Of course, Sweden was playing in the World Cup that night, which might have had something to do with it...) Hours are shorter off-season; no boats run January-March.
In 2013, the tour costs SEK 165. Children 6-11 years old may ride for half an adult fare. No fare for children 5 and under. There might be a discount with Stockholm Card -- it doesn't hurt to ask.
There are many boat tours that you can take in Stockholm, located on the water as it is. The one that I liked the best though was the one that you can take on a reproduction Viking longboat. This boat, as well as many others, is located on the pier across from the Royal Palace. See the operators for prices and sailing times.
Boat rides are a wonderful opportunity to see the beauty of Stockholm central area, as well as the many islands of the archipelago that spreads outside Stockholm.
I personally think that the Ferries that connect central Stockholm to the islands in the archipelago are the best choice for a boat ride in Stockholm.
For a good perspective of the Old Town, from the sea, a good choice is the ferry connecting Skansen to the main Stockholm. And it's included on the daily or 3 day ticket for the public transportation.
There are also a large number of sightseeing tours, but in this case you should look well before you choose one (see tourist traps).
A good way to see the city is by taking one of the boat tours on offer. The tours vary throughout the year but there is always at least one tour you can take.
As I was in Stockholm in January I took the Stockholm Winter Tour. The tour took about 1hr. and 15mins and took me out of Stockholm Harbour and towards the archipelago. The tour takes a different course on the way back and passes the Vasa Museum and Nordiska Museum.
The tour gives great views of Stockholm and it's archipelago and has a live English or Swedish speaking guide. The winter tour costs SEK 170 for the tour or SEK 230 for the tour + lunch.
We took a boat to Djurgarden.. it was very nice to travel by boat and watch the city from boat.. You can also take boat tours to some other places..
Djurgarden is a nice place to rest and have apicnic.. if you are lucky with the weather..
A great way to see the city is by river.
The tour passes narrow canals, around the Old Town, many famous buildings and between the city islands in Lake Mälaren
This is a must in Stockholm. The city is built on the water. In order to see it properly you have to travel by water.
